+   We don't sort when inserting.  Also, we sort and eliminate

-/* Prologue analysis.  */
-
-/* When we analyze a prologue, we're really doing 'abstract
-   interpretation' or 'pseudo-evaluation': running the function's code
-   in simulation, but using conservative approximations of the values
-   it would have when it actually runs.  For example, if our function
-   starts with the instruction:
-
-      ahi r1, 42     # add halfword immediate 42 to r1
-
-   we don't know exactly what value will be in r1 after executing this
-   instruction, but we do know it'll be 42 greater than its original
-   value.
-
-   If we then see an instruction like:
-
-      ahi r1, 22     # add halfword immediate 22 to r1
-
-   we still don't know what r1's value is, but again, we can say it is
-   now 64 greater than its original value.
-
-   If the next instruction were:
-
-      lr r2, r1      # set r2 to r1's value
-
-   then we can say that r2's value is now the original value of r1
-   plus 64.  And so on.
-
-   Of course, this can only go so far before it gets unreasonable.  If
-   we wanted to be able to say anything about the value of r1 after
-   the instruction:
-
-      xr r1, r3      # exclusive-or r1 and r3, place result in r1
-
-   then things would get pretty complex.  But remember, we're just
-   doing a conservative approximation; if exclusive-or instructions
-   aren't relevant to prologues, we can just say r1's value is now
-   'unknown'.  We can ignore things that are too complex, if that loss
-   of information is acceptable for our application.
-
-   Once you've reached an instruction that you don't know how to
-   simulate, you stop.  Now you examine the state of the registers and
-   stack slots you've kept track of.  For example:
-
-   - To see how large your stack frame is, just check the value of sp;
-     if it's the original value of sp minus a constant, then that
-     constant is the stack frame's size.  If the sp's value has been
-     marked as 'unknown', then that means the prologue has done
-     something too complex for us to track, and we don't know the
-     frame size.
-
-   - To see whether we've saved the SP in the current frame's back
-     chain slot, we just check whether the current value of the back
-     chain stack slot is the original value of the sp.
-
-   Sure, this takes some work.  But prologue analyzers aren't
-   quick-and-simple pattern patching to recognize a few fixed prologue
-   forms any more; they're big, hairy functions.  Along with inferior
-   function calls, prologue analysis accounts for a substantial
-   portion of the time needed to stabilize a GDB port.  So I think
-   it's worthwhile to look for an approach that will be easier to
-   understand and maintain.  In the approach used here:
-
-   - It's easier to see that the analyzer is correct: you just see
-     whether the analyzer properly (albiet conservatively) simulates
-     the effect of each instruction.
-
-   - It's easier to extend the analyzer: you can add support for new
-     instructions, and know that you haven't broken anything that
-     wasn't already broken before.
-
-   - It's orthogonal: to gather new information, you don't need to
-     complicate the code for each instruction.  As long as your domain
-     of conservative values is already detailed enough to tell you
-     what you need, then all the existing instruction simulations are
-     already gathering the right data for you.
-
-   A 'struct prologue_value' is a conservative approximation of the
-   real value the register or stack slot will have.  */

+Return a stream @var{fp} for a pipe connected to the standard input of

+You must have passed @code{PEX_USE_PIPES} to the @code{pex_init} call
+that returned @var{obj}.
+
+You must close @var{fp} using @code{fclose} yourself when you have
+finished writing data to the pipeline.
+
+The file descriptor underlying @var{fp} is marked not to be inherited
+by child processes.
+
+On systems that do not support pipes, this function returns
+@code{NULL}, and sets @code{errno} to @code{EINVAL}.  If you would
+like to write code that is portable to all systems the @code{pex}
+functions support, consider using @code{pex_input_file} instead.
+
+There are two opportunities for deadlock using
+@code{pex_input_pipe}:
+
+@itemize @bullet
+@item
+Most systems' pipes can buffer only a fixed amount of data; a process
+that writes to a full pipe blocks.  Thus, if you write to @file{fp}
+before starting the first process, you run the risk of blocking when
+there is no child process yet to read the data and allow you to
+continue.  @code{pex_input_pipe} makes no promises about the
+size of the pipe's buffer, so if you need to write any data at all
+before starting the first process in the pipeline, consider using
+@code{pex_input_file} instead.
+
+@item
+Using @code{pex_input_pipe} and @code{pex_read_output} together
+may also cause deadlock.  If the output pipe fills up, so that each
+program in the pipeline is waiting for the next to read more data, and
+you fill the input pipe by writing more data to @var{fp}, then there
+is no way to make progress: the only process that could read data from
+the output pipe is you, but you are blocked on the input pipe.

+
+Return a stream for a temporary file to pass to the first program in
+the pipeline as input.
+
+The name of the input file is chosen according to the same rules
+@code{pex_run} uses to choose output file names, based on
+@var{in_name}, @var{obj} and the @code{PEX_SUFFIX} bit in @var{flags}.
+
+Don't call @code{fclose} on the returned stream; the first call to
+@code{pex_run} closes it automatically.
+
+If @var{flags} includes @code{PEX_BINARY_OUTPUT}, open the stream in
+binary mode; otherwise, open it in the default mode.  Including
+@code{PEX_BINARY_OUTPUT} in @var{flags} has no effect on Unix.

+
+Return a stream @var{fp} for a pipe connected to the standard input of
+the first program in the pipeline; @var{fp} is opened for writing.
+You must have passed @code{PEX_USE_PIPES} to the @code{pex_init} call
+that returned @var{obj}.
+
+You must close @var{fp} using @code{fclose} yourself when you have
+finished writing data to the pipeline.
+
+The file descriptor underlying @var{fp} is marked not to be inherited
+by child processes.
+
+On systems that do not support pipes, this function returns
+@code{NULL}, and sets @code{errno} to @code{EINVAL}.  If you would
+like to write code that is portable to all systems the @code{pex}
+functions support, consider using @code{pex_input_file} instead.
+
+There are two opportunities for deadlock using
+@code{pex_input_pipe}:
+
+@itemize @bullet
+@item
+Most systems' pipes can buffer only a fixed amount of data; a process
+that writes to a full pipe blocks.  Thus, if you write to @file{fp}
+before starting the first process, you run the risk of blocking when
+there is no child process yet to read the data and allow you to
+continue.  @code{pex_input_pipe} makes no promises about the
+size of the pipe's buffer, so if you need to write any data at all
+before starting the first process in the pipeline, consider using
+@code{pex_input_file} instead.
+
+@item
+Using @code{pex_input_pipe} and @code{pex_read_output} together
+may also cause deadlock.  If the output pipe fills up, so that each
+program in the pipeline is waiting for the next to read more data, and
+you fill the input pipe by writing more data to @var{fp}, then there
+is no way to make progress: the only process that could read data from
+the output pipe is you, but you are blocked on the input pipe.

+This is a terse description of the new features added to readline-5.1 since
+the release of readline-5.0.
+
+1.  New Features in Readline
+
+a.  The key sequence sent by the keypad `delete' key is now automatically   
+    bound to delete-char.
+
+b.  A negative argument to menu-complete now cycles backward through the
+    completion list.
+
+c.  A new bindable readline variable:  bind-tty-special-chars.  If non-zero,
+    readline will bind the terminal special characters to their readline
+    equivalents when it's called (on by default).
+
+d.  New bindable command: vi-rubout.  Saves deleted text for possible  
+    reinsertion, as with any vi-mode `text modification' command; `X' is bound
+    to this in vi command mode.
+
+e.  If the rl_completion_query_items is set to a value < 0, readline never
+    asks the user whether or not to view the possible completions.
+
+f.  New application-callable auxiliary function, rl_variable_value, returns
+    a string corresponding to a readline variable's value.
+
+g.  When parsing inputrc files and variable binding commands, the parser
+    strips trailing whitespace from values assigned to boolean variables
+    before checking them.
+
+h.  A new external application-controllable variable that allows the LINES
+    and COLUMNS environment variables to set the window size regardless of
+    what the kernel returns.

+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{free} in the sense of freedom: to
+assure everyone the effective freedom to copy and redistribute it,
+with or without modifying it, either commercially or noncommercially.
+Secondarily, this License preserves for the author and publisher a way
+to get credit for their work, while not being considered responsible
+for modifications made by others.
+
+This License is a kind of ``copyleft'', which means that derivative
+works of the document must themselves be free in the same sense.  It
+complements the GNU General Public License, which is a copyleft
+license designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free
+program should come with manuals providing the same freedoms that the
+software does.  But this License is not limited to software manuals;
+it can be used for any textual work, regardless of subject matter or
+whether it is published as a printed book.  We recommend this License
+principally for works whose purpose is instruction or reference.
+
+@item
+APPLICABILITY AND DEFINITIONS
+
+This License applies to any manual or other work, in any medium, that
+contains a notice placed by the copyright holder saying it can be
+distributed under the terms of this License.  Such a notice grants a
+world-wide, royalty-free license, unlimited in duration, to use that
+work under the conditions stated herein.  The ``Document'', below,
+refers to any such manual or work.  Any member of the public is a
+licensee, and is addressed as ``you''.  You accept the license if you
+copy, modify or distribute the work in a way requiring permission
+under copyright law.
+
+A ``Modified Version'' of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+A ``Secondary Section'' is a named appendix or a front-matter section
+of the Document that deals exclusively with the relationship of the
+publishers or authors of the Document to the Document's overall
+subject (or to related matters) and contains nothing that could fall
+directly within that overall subject.  (Thus, if the Document is in
+part a textbook of mathematics, a Secondary Section may not explain
+any mathematics.)  The relationship could be a matter of historical
+connection with the subject or with related matters, or of legal,
+commercial, philosophical, ethical or political position regarding
+them.
+
+The ``Invariant Sections'' are certain Secondary Sections whose titles
+are designated, as being those of Invariant Sections, in the notice
+that says that the Document is released under this License.  If a
+section does not fit the above definition of Secondary then it is not
+allowed to be designated as Invariant.  The Document may contain zero
+Invariant Sections.  If the Document does not identify any Invariant
+Sections then there are none.
+
+The ``Cover Texts'' are certain short passages of text that are listed,
+as Front-Cover Texts or Back-Cover Texts, in the notice that says that
+the Document is released under this License.  A Front-Cover Text may
+be at most 5 words, and a Back-Cover Text may be at most 25 words.
+
+A ``Transparent'' copy of the Document means a machine-readable copy,
+represented in a format whose specification is available to the
+general public, that is suitable for revising the document
+straightforwardly with generic text editors or (for images composed of
+pixels) generic paint programs or (for drawings) some widely available
+drawing editor, and that is suitable for input to text formatters or
+for automatic translation to a variety of formats suitable for input
+to text formatters.  A copy made in an otherwise Transparent file
+format whose markup, or absence of markup, has been arranged to thwart
+or discourage subsequent modification by readers is not Transparent.
+An image format is not Transparent if used for any substantial amount
+of text.  A copy that is not ``Transparent'' is called ``Opaque''.
+
+Examples of suitable formats for Transparent copies include plain
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification.  Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}.  Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{PDF} produced by some word processors for
+output purposes only.
+
+The ``Title Page'' means, for a printed book, the title page itself,
+plus such following pages as are needed to hold, legibly, the material
+this License requires to appear in the title page.  For works in
+formats which do not have any title page as such, ``Title Page'' means
+the text near the most prominent appearance of the work's title,
+preceding the beginning of the body of the text.
+
+A section ``Entitled XYZ'' means a named subunit of the Document whose
+title either is precisely XYZ or contains XYZ in parentheses following
+text that translates XYZ in another language.  (Here XYZ stands for a
+specific section name mentioned below, such as ``Acknowledgements'',
+``Dedications'', ``Endorsements'', or ``History''.)  To ``Preserve the Title''
+of such a section when you modify the Document means that it remains a
+section ``Entitled XYZ'' according to this definition.
+
+The Document may include Warranty Disclaimers next to the notice which
+states that this License applies to the Document.  These Warranty
+Disclaimers are considered to be included by reference in this
+License, but only as regards disclaiming warranties: any other
+implication that these Warranty Disclaimers may have is void and has
+no effect on the meaning of this License.
+
+@item
+VERBATIM COPYING
+
+You may copy and distribute the Document in any medium, either
+commercially or noncommercially, provided that this License, the
+copyright notices, and the license notice saying this License applies
+to the Document are reproduced in all copies, and that you add no other
+conditions whatsoever to those of this License.  You may not use
+technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute.  However, you may accept
+compensation in exchange for copies.  If you distribute a large enough
+number of copies you must also follow the conditions in section 3.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+@item
+COPYING IN QUANTITY
+
+If you publish printed copies (or copies in media that commonly have
+printed covers) of the Document, numbering more than 100, and the
+Document's license notice requires Cover Texts, you must enclose the
+copies in covers that carry, clearly and legibly, all these Cover
+Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
+the back cover.  Both covers must also clearly and legibly identify
+you as the publisher of these copies.  The front cover must present
+the full title with all words of the title equally prominent and
+visible.  You may add other material on the covers in addition.
+Copying with changes limited to the covers, as long as they preserve
+the title of the Document and satisfy these conditions, can be treated
+as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute Opaque copies of the Document numbering
+more than 100, you must either include a machine-readable Transparent
+copy along with each Opaque copy, or state in or with each Opaque copy
+a computer-network location from which the general network-using
+public has access to download using public-standard network protocols
+a complete Transparent copy of the Document, free of added material.
+If you use the latter option, you must take reasonably prudent steps,
+when you begin distribution of Opaque copies in quantity, to ensure
+that this Transparent copy will remain thus accessible at the stated
+location until at least one year after the last time you distribute an
+Opaque copy (directly or through your agents or retailers) of that
+edition to the public.
+
+It is requested, but not required, that you contact the authors of the
+Document well before redistributing any large number of copies, to give
+them a chance to provide you with an updated version of the Document.
+
+@item
+MODIFICATIONS
+
+You may copy and distribute a Modified Version of the Document under
+the conditions of sections 2 and 3 above, provided that you release
+the Modified Version under precisely this License, with the Modified
+Version filling the role of the Document, thus licensing distribution
+and modification of the Modified Version to whoever possesses a copy
+of it.  In addition, you must do these things in the Modified Version:
+
+@enumerate A
+@item
+Use in the Title Page (and on the covers, if any) a title distinct
+from that of the Document, and from those of previous versions
+(which should, if there were any, be listed in the History section
+of the Document).  You may use the same title as a previous version
+if the original publisher of that version gives permission.
+
+@item
+List on the Title Page, as authors, one or more persons or entities
+responsible for authorship of the modifications in the Modified
+Version, together with at least five of the principal authors of the
+Document (all of its principal authors, if it has fewer than five),
+unless they release you from this requirement.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+Include, immediately after the copyright notices, a license notice
+giving the public permission to use the Modified Version under the
+terms of this License, in the form shown in the Addendum below.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+Preserve the section Entitled ``History'', Preserve its Title, and add

+there is no section Entitled ``History'' in the Document, create one
+stating the title, year, authors, and publisher of the Document as
+given on its Title Page, then add an item describing the Modified
+Version as stated in the previous sentence.
+
+@item
+Preserve the network location, if any, given in the Document for
+public access to a Transparent copy of the Document, and likewise
+the network locations given in the Document for previous versions
+it was based on.  These may be placed in the ``History'' section.
+You may omit a network location for a work that was published at

+Preserve all the Invariant Sections of the Document,
+unaltered in their text and in their titles.  Section numbers
+or the equivalent are not considered part of the section titles.
+
+@item
+Delete any section Entitled ``Endorsements''.  Such a section
+may not be included in the Modified Version.

+@end enumerate
+
+If the Modified Version includes new front-matter sections or
+appendices that qualify as Secondary Sections and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant.  To do this, add their titles to the
+list of Invariant Sections in the Modified Version's license notice.
+These titles must be distinct from any other section titles.
+
+You may add a section Entitled ``Endorsements'', provided it contains
+nothing but endorsements of your Modified Version by various
+parties---for example, statements of peer review or that the text has
+been approved by an organization as the authoritative definition of a
+standard.
+
+You may add a passage of up to five words as a Front-Cover Text, and a
+passage of up to 25 words as a Back-Cover Text, to the end of the list
+of Cover Texts in the Modified Version.  Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or
+through arrangements made by) any one entity.  If the Document already
+includes a cover text for the same cover, previously added by you or
+by arrangement made by the same entity you are acting on behalf of,
+you may not add another; but you may replace the old one, on explicit
+permission from the previous publisher that added the old one.
+
+The author(s) and publisher(s) of the Document do not by this License
+give permission to use their names for publicity for or to assert or
+imply endorsement of any Modified Version.
+
+@item
+COMBINING DOCUMENTS
+
+You may combine the Document with other documents released under this
+License, under the terms defined in section 4 above for modified
+versions, provided that you include in the combination all of the
+Invariant Sections of all of the original documents, unmodified, and
+list them all as Invariant Sections of your combined work in its
+license notice, and that you preserve all their Warranty Disclaimers.
+
+The combined work need only contain one copy of this License, and
+multiple identical Invariant Sections may be replaced with a single
+copy.  If there are multiple Invariant Sections with the same name but
+different contents, make the title of each such section unique by
+adding at the end of it, in parentheses, the name of the original
+author or publisher of that section if known, or else a unique number.
+Make the same adjustment to the section titles in the list of
+Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections Entitled ``History''
+in the various original documents, forming one section Entitled
+``History''; likewise combine any sections Entitled ``Acknowledgements'',
+and any sections Entitled ``Dedications''.  You must delete all
+sections Entitled ``Endorsements.''
+
+@item
+COLLECTIONS OF DOCUMENTS
+
+You may make a collection consisting of the Document and other documents
+released under this License, and replace the individual copies of this
+License in the various documents with a single copy that is included in
+the collection, provided that you follow the rules of this License for
+verbatim copying of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and distribute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+@item
+AGGREGATION WITH INDEPENDENT WORKS
+
+A compilation of the Document or its derivatives with other separate
+and independent documents or works, in or on a volume of a storage or
+distribution medium, is called an ``aggregate'' if the copyright
+resulting from the compilation is not used to limit the legal rights
+of the compilation's users beyond what the individual works permit.
+When the Document is included an aggregate, this License does not
+apply to the other works in the aggregate which are not themselves
+derivative works of the Document.
+
+If the Cover Text requirement of section 3 is applicable to these
+copies of the Document, then if the Document is less than one half of
+the entire aggregate, the Document's Cover Texts may be placed on
+covers that bracket the Document within the aggregate, or the
+electronic equivalent of covers if the Document is in electronic form.
+Otherwise they must appear on printed covers that bracket the whole
+aggregate.
+
+@item
+TRANSLATION
+
+Translation is considered a kind of modification, so you may
+distribute translations of the Document under the terms of section 4.
+Replacing Invariant Sections with translations requires special
+permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections.  You may include a
+translation of this License, and all the license notices in the
+Document, and any Warranty Disclaimers, provided that you also include
+the original English version of this License and the original versions
+of those notices and disclaimers.  In case of a disagreement between
+the translation and the original version of this License or a notice
+or disclaimer, the original version will prevail.
+
+If a section in the Document is Entitled ``Acknowledgements'',
+``Dedications'', or ``History'', the requirement (section 4) to Preserve
+its Title (section 1) will typically require changing the actual
+title.
+
+@item
+TERMINATION
+
+You may not copy, modify, sublicense, or distribute the Document except
+as expressly provided for under this License.  Any other attempt to
+copy, modify, sublicense or distribute the Document is void, and will
+automatically terminate your rights under this License.  However,
+parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such
+parties remain in full compliance.

+It should be considered a technical guide.
+For information on the interactive use of @sc{gnu} History, @pxref{Using
+History Interactively}.

+@node Introduction to History
+@section Introduction to History
+
+Many programs read input from the user a line at a time.  The @sc{gnu}
+History library is able to keep track of those lines, associate arbitrary
+data with each line, and utilize information from previous lines in
+composing new ones. 
+
+The programmer using the History library has available functions
+for remembering lines on a history list, associating arbitrary data
+with a line, removing lines from the list, searching through the list
+for a line containing an arbitrary text string, and referencing any line
+in the list directly.  In addition, a history @dfn{expansion} function
+is available which provides for a consistent user interface across
+different programs.
+
+The user using programs written with the History library has the
+benefit of a consistent user interface with a set of well-known
+commands for manipulating the text of previous lines and using that text
+in new commands.  The basic history manipulation commands are similar to
+the history substitution provided by @code{csh}.
+
+If the programmer desires, he can use the Readline library, which
+includes some history manipulation by default, and has the added
+advantage of command line editing.
+
+Before declaring any functions using any functionality the History
+library provides in other code, an application writer should include
+the file @code{<readline/history.h>} in any file that uses the
+History library's features.  It supplies extern declarations for all
+of the library's public functions and variables, and declares all of
+the public data structures.
+
+@node History Storage
+@section History Storage
+
+The history list is an array of history entries.  A history entry is
+declared as follows:
+
+@example
+typedef void *histdata_t;
+
+typedef struct _hist_entry @{
+  char *line;
+  char *timestamp;
+  histdata_t data;
+@} HIST_ENTRY;
+@end example
+
+The history list itself might therefore be declared as
+
+@example
+HIST_ENTRY **the_history_list;
+@end example
+
+The state of the History library is encapsulated into a single structure:
+
+@example
+/*
+ * A structure used to pass around the current state of the history.
+ */
+typedef struct _hist_state @{
+  HIST_ENTRY **entries; /* Pointer to the entries themselves. */
+  int offset;           /* The location pointer within this array. */
+  int length;           /* Number of elements within this array. */
+  int size;             /* Number of slots allocated to this array. */
+  int flags;
+@} HISTORY_STATE;
+@end example
+
+If the flags member includes @code{HS_STIFLED}, the history has been
+stifled.
+
+@node History Functions
+@section History Functions
+
+This section describes the calling sequence for the various functions
+exported by the @sc{gnu} History library.
+
+@menu
+* Initializing History and State Management::	Functions to call when you
+						want to use history in a
+						program.

+
+@node Initializing History and State Management
+@subsection Initializing History and State Management
+
+This section describes functions used to initialize and manage
+the state of the History library when you want to use the history
+functions in your program.
+
+@deftypefun void using_history (void)
+Begin a session in which the history functions might be used.  This
+initializes the interactive variables.
+@end deftypefun
+
+@deftypefun {HISTORY_STATE *} history_get_history_state (void)
+Return a structure describing the current state of the input history.
+@end deftypefun
+
+@deftypefun void history_set_history_state (HISTORY_STATE *state)
+Set the state of the history list according to @var{state}.
+@end deftypefun
+
+@node History List Management
+@subsection History List Management
+
+These functions manage individual entries on the history list, or set
+parameters managing the list itself.
+
+@deftypefun void add_history (const char *string)
+Place @var{string} at the end of the history list.  The associated data
+field (if any) is set to @code{NULL}.
+@end deftypefun
+
+@deftypefun void add_history_time (const char *string)
+Change the time stamp associated with the most recent history entry to
+@var{string}.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} remove_history (int which)
+Remove history entry at offset @var{which} from the history.  The
+removed element is returned so you can free the line, data,
+and containing structure.
+@end deftypefun
+
+@deftypefun {histdata_t} free_history_entry (HIST_ENTRY *histent)
+Free the history entry @var{histent} and any history library private
+data associated with it.  Returns the application-specific data
+so the caller can dispose of it.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} replace_history_entry (int which, const char *line, histdata_t data)
+Make the history entry at offset @var{which} have @var{line} and @var{data}.
+This returns the old entry so the caller can dispose of any
+application-specific data.  In the case
+of an invalid @var{which}, a @code{NULL} pointer is returned.
+@end deftypefun
+
+@deftypefun void clear_history (void)
+Clear the history list by deleting all the entries.
+@end deftypefun
+
+@deftypefun void stifle_history (int max)
+Stifle the history list, remembering only the last @var{max} entries.
+@end deftypefun
+
+@deftypefun int unstifle_history (void)
+Stop stifling the history.  This returns the previously-set
+maximum number of history entries (as set by @code{stifle_history()}).
+The value is positive if the history was
+stifled, negative if it wasn't.
+@end deftypefun
+
+@deftypefun int history_is_stifled (void)
+Returns non-zero if the history is stifled, zero if it is not.
+@end deftypefun
+
+@node Information About the History List
+@subsection Information About the History List
+
+These functions return information about the entire history list or
+individual list entries.
+
+@deftypefun {HIST_ENTRY **} history_list (void)
+Return a @code{NULL} terminated array of @code{HIST_ENTRY *} which is the
+current input history.  Element 0 of this list is the beginning of time.
+If there is no history, return @code{NULL}.
+@end deftypefun
+
+@deftypefun int where_history (void)
+Returns the offset of the current history element.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} current_history (void)
+Return the history entry at the current position, as determined by
+@code{where_history()}.  If there is no entry there, return a @code{NULL}
+pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} history_get (int offset)
+Return the history entry at position @var{offset}, starting from
+@code{history_base} (@pxref{History Variables}).
+If there is no entry there, or if @var{offset}
+is greater than the history length, return a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun time_t history_get_time (HIST_ENTRY *entry)
+Return the time stamp associated with the history entry @var{entry}.
+@end deftypefun
+
+@deftypefun int history_total_bytes (void)
+Return the number of bytes that the primary history entries are using.
+This function returns the sum of the lengths of all the lines in the
+history.
+@end deftypefun
+
+@node Moving Around the History List
+@subsection Moving Around the History List
+
+These functions allow the current index into the history list to be
+set or changed.
+
+@deftypefun int history_set_pos (int pos)
+Set the current history offset to @var{pos}, an absolute index
+into the list.
+Returns 1 on success, 0 if @var{pos} is less than zero or greater
+than the number of history entries.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} previous_history (void)
+Back up the current history offset to the previous history entry, and
+return a pointer to that entry.  If there is no previous entry, return
+a @code{NULL} pointer.
+@end deftypefun
+
+@deftypefun {HIST_ENTRY *} next_history (void)
+Move the current history offset forward to the next history entry, and
+return the a pointer to that entry.  If there is no next entry, return
+a @code{NULL} pointer.
+@end deftypefun
+
+@node Searching the History List
+@subsection Searching the History List
+@cindex History Searching
+
+These functions allow searching of the history list for entries containing
+a specific string.  Searching may be performed both forward and backward
+from the current history position.  The search may be @dfn{anchored},
+meaning that the string must match at the beginning of the history entry.
+@cindex anchored search
+
+@deftypefun int history_search (const char *string, int direction)
+Search the history for @var{string}, starting at the current history offset.
+If @var{direction} is less than 0, then the search is through
+previous entries, otherwise through subsequent entries.
+If @var{string} is found, then
+the current history index is set to that history entry, and the value
+returned is the offset in the line of the entry where
+@var{string} was found.  Otherwise, nothing is changed, and a -1 is
+returned.
+@end deftypefun
+
+@deftypefun int history_search_prefix (const char *string, int direction)
+Search the history for @var{string}, starting at the current history
+offset.  The search is anchored: matching lines must begin with
+@var{string}.  If @var{direction} is less than 0, then the search is
+through previous entries, otherwise through subsequent entries.
+If @var{string} is found, then the
+current history index is set to that entry, and the return value is 0. 
+Otherwise, nothing is changed, and a -1 is returned. 
+@end deftypefun
+
+@deftypefun int history_search_pos (const char *string, int direction, int pos)
+Search for @var{string} in the history list, starting at @var{pos}, an
+absolute index into the list.  If @var{direction} is negative, the search
+proceeds backward from @var{pos}, otherwise forward.  Returns the absolute
+index of the history element where @var{string} was found, or -1 otherwise.
+@end deftypefun
+
+@node Managing the History File
+@subsection Managing the History File
+
+The History library can read the history from and write it to a file.
+This section documents the functions for managing a history file.
+
+@deftypefun int read_history (const char *filename)
+Add the contents of @var{filename} to the history list, a line at a time.
+If @var{filename} is @code{NULL}, then read from @file{~/.history}.
+Returns 0 if successful, or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int read_history_range (const char *filename, int from, int to)
+Read a range of lines from @var{filename}, adding them to the history list.
+Start reading at line @var{from} and end at @var{to}.
+If @var{from} is zero, start at the beginning.  If @var{to} is less than
+@var{from}, then read until the end of the file.  If @var{filename} is
+@code{NULL}, then read from @file{~/.history}.  Returns 0 if successful,
+or @code{errno} if not.
+@end deftypefun
+
+@deftypefun int write_history (const char *filename)
+Write the current history to @var{filename}, overwriting @var{filename}
+if necessary.
+If @var{filename} is @code{NULL}, then write the history list to
+@file{~/.history}.
+Returns 0 on success, or @code{errno} on a read or write error.
+@end deftypefun
+
+@deftypefun int append_history (int nelements, const char *filename)
+Append the last @var{nelements} of the history list to @var{filename}.
+If @var{filename} is @code{NULL}, then append to @file{~/.history}.
+Returns 0 on success, or @code{errno} on a read or write error.
+@end deftypefun
+
+@deftypefun int history_truncate_file (const char *filename, int nlines)
+Truncate the history file @var{filename}, leaving only the last
+@var{nlines} lines.
+If @var{filename} is @code{NULL}, then @file{~/.history} is truncated.
+Returns 0 on success, or @code{errno} on failure.
+@end deftypefun
+
+@node History Expansion
+@subsection History Expansion
+
+These functions implement history expansion.
+
+@deftypefun int history_expand (char *string, char **output)
+Expand @var{string}, placing the result into @var{output}, a pointer
+to a string (@pxref{History Interaction}).  Returns:

+@node History Variables
+@section History Variables
+
+This section describes the externally-visible variables exported by

+
+@deftypevar int history_base
+The logical offset of the first entry in the history list.
+@end deftypevar
+
+@deftypevar int history_length
+The number of entries currently stored in the history list.
+@end deftypevar
+
+@deftypevar int history_max_entries
+The maximum number of history entries.  This must be changed using
+@code{stifle_history()}.
+@end deftypevar
+
+@deftypevar int history_write_timestamps
+If non-zero, timestamps are written to the history file, so they can be
+preserved between sessions.  The default value is 0, meaning that
+timestamps are not saved.
+@end deftypevar
+
+@deftypevar char history_expansion_char
+The character that introduces a history event.  The default is @samp{!}.
+Setting this to 0 inhibits history expansion.
+@end deftypevar
+
+@deftypevar char history_subst_char
+The character that invokes word substitution if found at the start of
+a line.  The default is @samp{^}.
+@end deftypevar
+
+@deftypevar char history_comment_char
+During tokenization, if this character is seen as the first character
+of a word, then it and all subsequent characters up to a newline are
+ignored, suppressing history expansion for the remainder of the line.
+This is disabled by default.
+@end deftypevar
+
+@deftypevar {char *} history_word_delimiters
+The characters that separate tokens for @code{history_tokenize()}.
+The default value is @code{" \t\n()<>;&|"}.
+@end deftypevar
+
+@deftypevar {char *} history_search_delimiter_chars
+The list of additional characters which can delimit a history search
+string, in addition to space, TAB, @samp{:} and @samp{?} in the case of
+a substring search.  The default is empty.
+@end deftypevar
+
+@deftypevar {char *} history_no_expand_chars
+The list of characters which inhibit history expansion if found immediately
+following @var{history_expansion_char}.  The default is space, tab, newline,
+carriage return, and @samp{=}.
+@end deftypevar
+
+@deftypevar int history_quotes_inhibit_expansion
+If non-zero, single-quoted words are not scanned for the history expansion
+character.  The default value is 0.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} history_inhibit_expansion_function
+This should be set to the address of a function that takes two arguments:
+a @code{char *} (@var{string})
+and an @code{int} index into that string (@var{i}).
+It should return a non-zero value if the history expansion starting at
+@var{string[i]} should not be performed; zero if the expansion should
+be done.
+It is intended for use by applications like Bash that use the history
+expansion character for additional purposes.
+By default, this variable is set to @code{NULL}.

+@cindex command history
+@cindex history list
+
+When the @option{-o history} option to the @code{set} builtin
+is enabled (@pxref{The Set Builtin}),
+the shell provides access to the @dfn{command history},
+the list of commands previously typed.
+The value of the @env{HISTSIZE} shell variable is used as the
+number of commands to save in a history list.
+The text of the last @env{$HISTSIZE}
+commands (default 500) is saved.
+The shell stores each command in the history list prior to
+parameter and variable expansion
+but after history expansion is performed, subject to the
+values of the shell variables
+@env{HISTIGNORE} and @env{HISTCONTROL}.
+
+When the shell starts up, the history is initialized from the
+file named by the @env{HISTFILE} variable (default @file{~/.bash_history}).
+The file named by the value of @env{HISTFILE} is truncated, if
+necessary, to contain no more than the number of lines specified by
+the value of the @env{HISTFILESIZE} variable.
+When an interactive shell exits, the last
+@env{$HISTSIZE} lines are copied from the history list to the file
+named by @env{$HISTFILE}.
+If the @code{histappend} shell option is set (@pxref{Bash Builtins}),
+the lines are appended to the history file,
+otherwise the history file is overwritten.
+If @env{HISTFILE}
+is unset, or if the history file is unwritable, the history is
+not saved.  After saving the history, the history file is truncated
+to contain no more than @env{$HISTFILESIZE}
+lines.  If @env{HISTFILESIZE} is not set, no truncation is performed.
+
+If the @env{HISTTIMEFORMAT} is set, the time stamp information
+associated with each history entry is written to the history file.
+
+The builtin command @code{fc} may be used to list or edit and re-execute
+a portion of the history list.
+The @code{history} builtin may be used to display or modify the history
+list and manipulate the history file.
+When using command-line editing, search commands
+are available in each editing mode that provide access to the
+history list (@pxref{Commands For History}).
+
+The shell allows control over which commands are saved on the history
+list.  The @env{HISTCONTROL} and @env{HISTIGNORE}
+variables may be set to cause the shell to save only a subset of the
+commands entered.
+The @code{cmdhist}
+shell option, if enabled, causes the shell to attempt to save each
+line of a multi-line command in the same history entry, adding
+semicolons where necessary to preserve syntactic correctness.
+The @code{lithist}
+shell option causes the shell to save the command with embedded newlines
+instead of semicolons.
+The @code{shopt} builtin is used to set these options.
+@xref{Bash Builtins}, for a description of @code{shopt}.
+
+@node Bash History Builtins
+@section Bash History Builtins
+@cindex history builtins
+
+Bash provides two builtin commands which manipulate the
+history list and history file.
+
+@table @code
+
+@item fc
+@btindex fc
+@example
+@code{fc [-e @var{ename}] [-nlr] [@var{first}] [@var{last}]}
+@code{fc -s [@var{pat}=@var{rep}] [@var{command}]}
+@end example
+
+Fix Command.  In the first form, a range of commands from @var{first} to
+@var{last} is selected from the history list.  Both @var{first} and
+@var{last} may be specified as a string (to locate the most recent
+command beginning with that string) or as a number (an index into the
+history list, where a negative number is used as an offset from the
+current command number).  If @var{last} is not specified it is set to
+@var{first}.  If @var{first} is not specified it is set to the previous
+command for editing and @minus{}16 for listing.  If the @option{-l} flag is
+given, the commands are listed on standard output.  The @option{-n} flag
+suppresses the command numbers when listing.  The @option{-r} flag
+reverses the order of the listing.  Otherwise, the editor given by
+@var{ename} is invoked on a file containing those commands.  If
+@var{ename} is not given, the value of the following variable expansion
+is used: @code{$@{FCEDIT:-$@{EDITOR:-vi@}@}}.  This says to use the
+value of the @env{FCEDIT} variable if set, or the value of the
+@env{EDITOR} variable if that is set, or @code{vi} if neither is set.
+When editing is complete, the edited commands are echoed and executed.
+
+In the second form, @var{command} is re-executed after each instance
+of @var{pat} in the selected command is replaced by @var{rep}.
+
+A useful alias to use with the @code{fc} command is @code{r='fc -s'}, so
+that typing @samp{r cc} runs the last command beginning with @code{cc}
+and typing @samp{r} re-executes the last command (@pxref{Aliases}).
+
+@item history
+@btindex history
+@example
+history [@var{n}]
+history -c
+history -d @var{offset}
+history [-anrw] [@var{filename}]
+history -ps @var{arg}
+@end example
+
+With no options, display the history list with line numbers.
+Lines prefixed with a @samp{*} have been modified.
+An argument of @var{n} lists only the last @var{n} lines.
+If the shell variable @env{HISTTIMEFORMAT} is set and not null,
+it is used as a format string for @var{strftime} to display
+the time stamp associated with each displayed history entry.
+No intervening blank is printed between the formatted time stamp
+and the history line.
+
+Options, if supplied, have the following meanings:
+
+@table @code
+@item -c
+Clear the history list.  This may be combined
+with the other options to replace the history list completely.
+
+@item -d @var{offset}
+Delete the history entry at position @var{offset}.
+@var{offset} should be specified as it appears when the history is
+displayed.
+
+@item -a
+Append the new
+history lines (history lines entered since the beginning of the
+current Bash session) to the history file.
+
+@item -n
+Append the history lines not already read from the history file
+to the current history list.  These are lines appended to the history
+file since the beginning of the current Bash session.
+
+@item -r
+Read the current history file and append its contents to
+the history list.
+
+@item -w
+Write out the current history to the history file.
+
+@item -p
+Perform history substitution on the @var{arg}s and display the result
+on the standard output, without storing the results in the history list.
+
+@item -s
+The @var{arg}s are added to the end of
+the history list as a single entry.
+
+@end table
+
+When any of the @option{-w}, @option{-r}, @option{-a}, or @option{-n} options is
+used, if @var{filename}
+is given, then it is used as the history file.  If not, then
+the value of the @env{HISTFILE} variable is used.
+
+@end table
+@end ifset
+
+@node History Interaction
+@section History Expansion
+@cindex history expansion
+
+The History library provides a history expansion feature that is similar
+to the history expansion provided by @code{csh}.  This section
+describes the syntax used to manipulate the history information.
+
+History expansions introduce words from the history list into
+the input stream, making it easy to repeat commands, insert the
+arguments to a previous command into the current input line, or
+fix errors in previous commands quickly.
+
+History expansion takes place in two parts.  The first is to determine
+which line from the history list should be used during substitution.
+The second is to select portions of that line for inclusion into the
+current one.  The line selected from the history is called the
+@dfn{event}, and the portions of that line that are acted upon are
+called @dfn{words}.  Various @dfn{modifiers} are available to manipulate
+the selected words.  The line is broken into words in the same fashion
+that Bash does, so that several words
+surrounded by quotes are considered one word.
+History expansions are introduced by the appearance of the
+history expansion character, which is @samp{!} by default.
+@ifset BashFeatures
+Only @samp{\} and @samp{'} may be used to escape the history expansion
+character.
+@end ifset
+
+@ifset BashFeatures
+Several shell options settable with the @code{shopt}
+builtin (@pxref{Bash Builtins}) may be used to tailor
+the behavior of history expansion.  If the
+@code{histverify} shell option is enabled, and Readline
+is being used, history substitutions are not immediately passed to
+the shell parser.
+Instead, the expanded line is reloaded into the Readline
+editing buffer for further modification.
+If Readline is being used, and the @code{histreedit}
+shell option is enabled, a failed history expansion will be
+reloaded into the Readline editing buffer for correction.
+The @option{-p} option to the @code{history} builtin command
+may be used to see what a history expansion will do before using it.
+The @option{-s} option to the @code{history} builtin may be used to
+add commands to the end of the history list without actually executing
+them, so that they are available for subsequent recall.
+This is most useful in conjunction with Readline.
+
+The shell allows control of the various characters used by the
+history expansion mechanism with the @code{histchars} variable.

+@cindex event designators
+
+An event designator is a reference to a command line entry in the
+history list.
+@cindex history events
+
+@table @asis
+
+@item @code{!}
+@ifset BashFeatures
+Start a history substitution, except when followed by a space, tab,

+@end ifset
+@ifclear BashFeatures
+Start a history substitution, except when followed by a space, tab,
+the end of the line, or @samp{=}.
+@end ifclear
+
+@item @code{!@var{n}}
+Refer to command line @var{n}.
+
+@item @code{!-@var{n}}
+Refer to the command @var{n} lines back.
+
+@item @code{!!}
+Refer to the previous command.  This is a synonym for @samp{!-1}.
+
+@item @code{!@var{string}}
+Refer to the most recent command starting with @var{string}.
+
+@item @code{!?@var{string}[?]}
+Refer to the most recent command containing @var{string}.  The trailing
+@samp{?} may be omitted if the @var{string} is followed immediately by
+a newline.
+
+@item @code{^@var{string1}^@var{string2}^}
+Quick Substitution.  Repeat the last command, replacing @var{string1}
+with @var{string2}.  Equivalent to
+@code{!!:s/@var{string1}/@var{string2}/}.
+
+@item @code{!#}
+The entire command line typed so far.
+
+@end table
+
+@node Word Designators
+@subsection Word Designators
+
+Word designators are used to select desired words from the event.
+A @samp{:} separates the event specification from the word designator.  It
+may be omitted if the word designator begins with a @samp{^}, @samp{$},
+@samp{*}, @samp{-}, or @samp{%}.  Words are numbered from the beginning
+of the line, with the first word being denoted by 0 (zero).  Words are
+inserted into the current line separated by single spaces.
+
+@need 0.75
+For example,
+
+@table @code
+@item !!
+designates the preceding command.  When you type this, the preceding
+command is repeated in toto.
+
+@item !!:$
+designates the last argument of the preceding command.  This may be
+shortened to @code{!$}.
+
+@item !fi:2
+designates the second argument of the most recent command starting with
+the letters @code{fi}.
+@end table
+
+@need 0.75
+Here are the word designators:
+ 
+@table @code
+
+@item 0 (zero)
+The @code{0}th word.  For many applications, this is the command word.
+
+@item @var{n}
+The @var{n}th word.
+
+@item ^
+The first argument; that is, word 1.
+
+@item $
+The last argument.
+
+@item %
+The word matched by the most recent @samp{?@var{string}?} search.
+
+@item @var{x}-@var{y}
+A range of words; @samp{-@var{y}} abbreviates @samp{0-@var{y}}.
+
+@item *
+All of the words, except the @code{0}th.  This is a synonym for @samp{1-$}.
+It is not an error to use @samp{*} if there is just one word in the event;
+the empty string is returned in that case.
+
+@item @var{x}*
+Abbreviates @samp{@var{x}-$}
+
+@item @var{x}-
+Abbreviates @samp{@var{x}-$} like @samp{@var{x}*}, but omits the last word.
+
+@end table
+
+If a word designator is supplied without an event specification, the
+previous command is used as the event.
+
+@node Modifiers
+@subsection Modifiers
+
+After the optional word designator, you can add a sequence of one or more
+of the following modifiers, each preceded by a @samp{:}.
+
+@table @code
+
+@item h
+Remove a trailing pathname component, leaving only the head.
+
+@item t
+Remove all leading  pathname  components, leaving the tail.
+
+@item r
+Remove a trailing suffix of the form @samp{.@var{suffix}}, leaving
+the basename.
+
+@item e
+Remove all but the trailing suffix.
+
+@item p
+Print the new command but do not execute it.
+
+@ifset BashFeatures
+@item q
+Quote the substituted words, escaping further substitutions.
+
+@item x
+Quote the substituted words as with @samp{q},
+but break into words at spaces, tabs, and newlines.
+@end ifset
+
+@item s/@var{old}/@var{new}/
+Substitute @var{new} for the first occurrence of @var{old} in the
+event line.  Any delimiter may be used in place of @samp{/}.
+The delimiter may be quoted in @var{old} and @var{new}
+with a single backslash.  If @samp{&} appears in @var{new},
+it is replaced by @var{old}.  A single backslash will quote
+the @samp{&}.  The final delimiter is optional if it is the last
+character on the input line.
+
+@item &
+Repeat the previous substitution.
+
+@item g
+@itemx a
+Cause changes to be applied over the entire event line.  Used in
+conjunction with @samp{s}, as in @code{gs/@var{old}/@var{new}/},
+or with @samp{&}.
+
+@item G
+Apply the following @samp{s} modifier once to each word in the event.

+@chapter Programming with GNU Readline
+
+This chapter describes the interface between the @sc{gnu} Readline Library and
+other programs.  If you are a programmer, and you wish to include the
+features found in @sc{gnu} Readline
+such as completion, line editing, and interactive history manipulation
+in your own programs, this section is for you.

+* Custom Functions::	Adding your own functions to Readline.

+					functions.
+* Readline Convenience Functions::	Functions which Readline supplies to

+@end menu
+
+@node Basic Behavior
+@section Basic Behavior
+
+Many programs provide a command line interface, such as @code{mail},
+@code{ftp}, and @code{sh}.  For such programs, the default behaviour of
+Readline is sufficient.  This section describes how to use Readline in
+the simplest way possible, perhaps to replace calls in your code to
+@code{gets()} or @code{fgets()}.
+
+@findex readline
+@cindex readline, function
+
+The function @code{readline()} prints a prompt @var{prompt}
+and then reads and returns a single line of text from the user.
+If @var{prompt} is @code{NULL} or the empty string, no prompt is displayed.
+The line @code{readline} returns is allocated with @code{malloc()};
+the caller should @code{free()} the line when it has finished with it.
+The declaration for @code{readline} in ANSI C is
+
+@example
+@code{char *readline (const char *@var{prompt});}
+@end example
+
+@noindent
+So, one might say
+@example
+@code{char *line = readline ("Enter a line: ");}
+@end example
+@noindent
+in order to read a line of text from the user.
+The line returned has the final newline removed, so only the
+text remains.
+
+If @code{readline} encounters an @code{EOF} while reading the line, and the
+line is empty at that point, then @code{(char *)NULL} is returned.
+Otherwise, the line is ended just as if a newline had been typed.
+
+If you want the user to be able to get at the line later, (with
+@key{C-p} for example), you must call @code{add_history()} to save the
+line away in a @dfn{history} list of such lines.
+
+@example
+@code{add_history (line)};
+@end example
+
+@noindent
+For full details on the GNU History Library, see the associated manual.
+
+It is preferable to avoid saving empty lines on the history list, since
+users rarely have a burning need to reuse a blank line.  Here is
+a function which usefully replaces the standard @code{gets()} library
+function, and has the advantage of no static buffer to overflow:
+
+@example
+/* A static variable for holding the line. */
+static char *line_read = (char *)NULL;
+
+/* Read a string, and return a pointer to it.
+   Returns NULL on EOF. */
+char *
+rl_gets ()
+@{
+  /* If the buffer has already been allocated,
+     return the memory to the free pool. */
+  if (line_read)
+    @{
+      free (line_read);
+      line_read = (char *)NULL;
+    @}
+
+  /* Get a line from the user. */
+  line_read = readline ("");
+
+  /* If the line has any text in it,
+     save it on the history. */
+  if (line_read && *line_read)
+    add_history (line_read);
+
+  return (line_read);
+@}
+@end example
+
+This function gives the user the default behaviour of @key{TAB}
+completion: completion on file names.  If you do not want Readline to
+complete on filenames, you can change the binding of the @key{TAB} key
+with @code{rl_bind_key()}.
+
+@example
+@code{int rl_bind_key (int @var{key}, rl_command_func_t *@var{function});}
+@end example
+
+@code{rl_bind_key()} takes two arguments: @var{key} is the character that
+you want to bind, and @var{function} is the address of the function to
+call when @var{key} is pressed.  Binding @key{TAB} to @code{rl_insert()}
+makes @key{TAB} insert itself.
+@code{rl_bind_key()} returns non-zero if @var{key} is not a valid
+ASCII character code (between 0 and 255).
+
+Thus, to disable the default @key{TAB} behavior, the following suffices:
+@example
+@code{rl_bind_key ('\t', rl_insert);}
+@end example
+
+This code should be executed once at the start of your program; you
+might write a function called @code{initialize_readline()} which
+performs this and other desired initializations, such as installing
+custom completers (@pxref{Custom Completers}).
+
+@node Custom Functions
+@section Custom Functions
+
+Readline provides many functions for manipulating the text of
+the line, but it isn't possible to anticipate the needs of all
+programs.  This section describes the various functions and variables
+defined within the Readline library which allow a user program to add
+customized functionality to Readline.
+
+Before declaring any functions that customize Readline's behavior, or
+using any functionality Readline provides in other code, an
+application writer should include the file @code{<readline/readline.h>}
+in any file that uses Readline's features.  Since some of the definitions
+in @code{readline.h} use the @code{stdio} library, the file
+@code{<stdio.h>} should be included before @code{readline.h}.
+
+@code{readline.h} defines a C preprocessor variable that should
+be treated as an integer, @code{RL_READLINE_VERSION}, which may
+be used to conditionally compile application code depending on
+the installed Readline version.  The value is a hexadecimal
+encoding of the major and minor version numbers of the library,
+of the form 0x@var{MMmm}.  @var{MM} is the two-digit major
+version number; @var{mm} is the two-digit minor version number. 
+For Readline 4.2, for example, the value of
+@code{RL_READLINE_VERSION} would be @code{0x0402}. 
+
+@menu
+* Readline Typedefs::	C declarations to make code readable.
+* Function Writing::	Variables and calling conventions.
+@end menu
+
+@node Readline Typedefs
+@subsection Readline Typedefs
+
+For readabilty, we declare a number of new object types, all pointers
+to functions.
+
+The reason for declaring these new types is to make it easier to write
+code describing pointers to C functions with appropriately prototyped
+arguments and return values.
+
+For instance, say we want to declare a variable @var{func} as a pointer
+to a function which takes two @code{int} arguments and returns an
+@code{int} (this is the type of all of the Readline bindable functions).
+Instead of the classic C declaration
+
+@code{int (*func)();}
+
+@noindent
+or the ANSI-C style declaration
+
+@code{int (*func)(int, int);}
+
+@noindent
+we may write
+
+@code{rl_command_func_t *func;}
+
+The full list of function pointer types available is
+
+@table @code
+@item typedef int rl_command_func_t (int, int);
+
+@item typedef char *rl_compentry_func_t (const char *, int);
+
+@item typedef char **rl_completion_func_t (const char *, int, int);
+
+@item typedef char *rl_quote_func_t (char *, int, char *);
+
+@item typedef char *rl_dequote_func_t (char *, int);
+
+@item typedef int rl_compignore_func_t (char **);
+
+@item typedef void rl_compdisp_func_t (char **, int, int);
+
+@item typedef int rl_hook_func_t (void);
+
+@item typedef int rl_getc_func_t (FILE *);
+
+@item typedef int rl_linebuf_func_t (char *, int);
+
+@item typedef int rl_intfunc_t (int);
+@item #define rl_ivoidfunc_t rl_hook_func_t
+@item typedef int rl_icpfunc_t (char *);
+@item typedef int rl_icppfunc_t (char **);
+
+@item typedef void rl_voidfunc_t (void);

+
+@node Function Writing
+@subsection Writing a New Function
+
+In order to write new functions for Readline, you need to know the
+calling conventions for keyboard-invoked functions, and the names of the
+variables that describe the current state of the line read so far.
+
+The calling sequence for a command @code{foo} looks like
+
+@example
+@code{int foo (int count, int key)}
+@end example
+
+@noindent
+where @var{count} is the numeric argument (or 1 if defaulted) and
+@var{key} is the key that invoked this function.
+
+It is completely up to the function as to what should be done with the
+numeric argument.  Some functions use it as a repeat count, some
+as a flag, and others to choose alternate behavior (refreshing the current
+line as opposed to refreshing the screen, for example).  Some choose to
+ignore it.  In general, if a
+function uses the numeric argument as a repeat count, it should be able
+to do something useful with both negative and positive arguments.
+At the very least, it should be aware that it can be passed a
+negative argument.
+
+A command function should return 0 if its action completes successfully,
+and a non-zero value if some error occurs.
+This is the convention obeyed by all of the builtin Readline bindable
+command functions.
+
+@node Readline Variables
+@section Readline Variables
+
+These variables are available to function writers.
+
+@deftypevar {char *} rl_line_buffer
+This is the line gathered so far.  You are welcome to modify the
+contents of the line, but see @ref{Allowing Undoing}.  The
+function @code{rl_extend_line_buffer} is available to increase
+the memory allocated to @code{rl_line_buffer}.
+@end deftypevar
+
+@deftypevar int rl_point
+The offset of the current cursor position in @code{rl_line_buffer}
+(the @emph{point}).
+@end deftypevar
+
+@deftypevar int rl_end
+The number of characters present in @code{rl_line_buffer}.  When
+@code{rl_point} is at the end of the line, @code{rl_point} and
+@code{rl_end} are equal.
+@end deftypevar
+
+@deftypevar int rl_mark
+The @var{mark} (saved position) in the current line.  If set, the mark
+and point define a @emph{region}.
+@end deftypevar
+
+@deftypevar int rl_done
+Setting this to a non-zero value causes Readline to return the current
+line immediately.
+@end deftypevar
+
+@deftypevar int rl_num_chars_to_read
+Setting this to a positive value before calling @code{readline()} causes
+Readline to return after accepting that many characters, rather
+than reading up to a character bound to @code{accept-line}.
+@end deftypevar
+
+@deftypevar int rl_pending_input
+Setting this to a value makes it the next keystroke read.  This is a
+way to stuff a single character into the input stream.
+@end deftypevar
+
+@deftypevar int rl_dispatching
+Set to a non-zero value if a function is being called from a key binding;
+zero otherwise.  Application functions can test this to discover whether
+they were called directly or by Readline's dispatching mechanism.
+@end deftypevar
+
+@deftypevar int rl_erase_empty_line
+Setting this to a non-zero value causes Readline to completely erase
+the current line, including any prompt, any time a newline is typed as
+the only character on an otherwise-empty line.  The cursor is moved to
+the beginning of the newly-blank line.
+@end deftypevar
+
+@deftypevar {char *} rl_prompt
+The prompt Readline uses.  This is set from the argument to
+@code{readline()}, and should not be assigned to directly.
+The @code{rl_set_prompt()} function (@pxref{Redisplay}) may
+be used to modify the prompt string after calling @code{readline()}.
+@end deftypevar
+
+@deftypevar int rl_already_prompted
+If an application wishes to display the prompt itself, rather than have
+Readline do it the first time @code{readline()} is called, it should set
+this variable to a non-zero value after displaying the prompt.
+The prompt must also be passed as the argument to @code{readline()} so
+the redisplay functions can update the display properly.
+The calling application is responsible for managing the value; Readline
+never sets it.
+@end deftypevar
+
+@deftypevar {const char *} rl_library_version
+The version number of this revision of the library.
+@end deftypevar
+
+@deftypevar int rl_readline_version
+An integer encoding the current version of the library.  The encoding is
+of the form 0x@var{MMmm}, where @var{MM} is the two-digit major version
+number, and @var{mm} is the two-digit minor version number.
+For example, for Readline-4.2, @code{rl_readline_version} would have the
+value 0x0402.
+@end deftypevar
+
+@deftypevar {int} rl_gnu_readline_p
+Always set to 1, denoting that this is @sc{gnu} readline rather than some
+emulation.
+@end deftypevar
+
+@deftypevar {const char *} rl_terminal_name
+The terminal type, used for initialization.  If not set by the application,
+Readline sets this to the value of the @env{TERM} environment variable
+the first time it is called.
+@end deftypevar
+
+@deftypevar {const char *} rl_readline_name
+This variable is set to a unique name by each application using Readline.
+The value allows conditional parsing of the inputrc file
+(@pxref{Conditional Init Constructs}).
+@end deftypevar
+
+@deftypevar {FILE *} rl_instream
+The stdio stream from which Readline reads input.
+If @code{NULL}, Readline defaults to @var{stdin}.
+@end deftypevar
+
+@deftypevar {FILE *} rl_outstream
+The stdio stream to which Readline performs output.
+If @code{NULL}, Readline defaults to @var{stdout}.
+@end deftypevar
+
+@deftypevar int rl_prefer_env_winsize
+If non-zero, Readline gives values found in the @env{LINES} and
+@env{COLUMNS} environment variables greater precedence than values fetched
+from the kernel when computing the screen dimensions.
+@end deftypevar
+
+@deftypevar {rl_command_func_t *} rl_last_func
+The address of the last command function Readline executed.  May be used to
+test whether or not a function is being executed twice in succession, for
+example.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_startup_hook
+If non-zero, this is the address of a function to call just
+before @code{readline} prints the first prompt.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_pre_input_hook
+If non-zero, this is the address of a function to call after
+the first prompt has been printed and just before @code{readline}
+starts reading input characters.
+@end deftypevar
+
+@deftypevar {rl_hook_func_t *} rl_event_hook
+If non-zero, this is the address of a function to call periodically
+when Readline is waiting for terminal input.
+By default, this will be called at most ten times a second if there
+is no keyboard input.
+@end deftypevar
+
+@deftypevar {rl_getc_func_t *} rl_getc_function
+If non-zero, Readline will call indirectly through this pointer
+to get a character from the input stream.  By default, it is set to
+@code{rl_getc}, the default Readline character input function
+(@pxref{Character Input}).
+@end deftypevar
+
+@deftypevar {rl_voidfunc_t *} rl_redisplay_function
+If non-zero, Readline will call indirectly through this pointer
+to update the display with the current contents of the editing buffer.
+By default, it is set to @code{rl_redisplay}, the default Readline
+redisplay function (@pxref{Redisplay}).
+@end deftypevar
+
+@deftypevar {rl_vintfunc_t *} rl_prep_term_function
+If non-zero, Readline will call indirectly through this pointer
+to initialize the terminal.  The function takes a single argument, an
+@code{int} flag that says whether or not to use eight-bit characters.
+By default, this is set to @code{rl_prep_terminal}
+(@pxref{Terminal Management}).
+@end deftypevar
+
+@deftypevar {rl_voidfunc_t *} rl_deprep_term_function
+If non-zero, Readline will call indirectly through this pointer
+to reset the terminal.  This function should undo the effects of
+@code{rl_prep_term_function}.
+By default, this is set to @code{rl_deprep_terminal}
+(@pxref{Terminal Management}).
+@end deftypevar
+
+@deftypevar {Keymap} rl_executing_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+currently executing readline function was found.
+@end deftypevar 
+
+@deftypevar {Keymap} rl_binding_keymap
+This variable is set to the keymap (@pxref{Keymaps}) in which the
+last key binding occurred.
+@end deftypevar 
+
+@deftypevar {char *} rl_executing_macro
+This variable is set to the text of any currently-executing macro.
+@end deftypevar
+
+@deftypevar {int} rl_readline_state
+A variable with bit values that encapsulate the current Readline state.
+A bit is set with the @code{RL_SETSTATE} macro, and unset with the
+@code{RL_UNSETSTATE} macro.  Use the @code{RL_ISSTATE} macro to test
+whether a particular state bit is set.  Current state bits include:
+
+@table @code
+@item RL_STATE_NONE
+Readline has not yet been called, nor has it begun to intialize.
+@item RL_STATE_INITIALIZING
+Readline is initializing its internal data structures.
+@item RL_STATE_INITIALIZED
+Readline has completed its initialization.
+@item RL_STATE_TERMPREPPED
+Readline has modified the terminal modes to do its own input and redisplay.
+@item RL_STATE_READCMD

+@item RL_STATE_METANEXT
+Readline is reading more input after reading the meta-prefix character.
+@item RL_STATE_DISPATCHING
+Readline is dispatching to a command.
+@item RL_STATE_MOREINPUT

+@item RL_STATE_UNDOING
+Readline is performing an undo.
+@item RL_STATE_DONE
+Readline has read a key sequence bound to @code{accept-line}
+and is about to return the line to the caller.
+@end table
+
+@end deftypevar

+
+@node Function Naming
+@subsection Naming a Function
+
+The user can dynamically change the bindings of keys while using
+Readline.  This is done by representing the function with a descriptive
+name.  The user is able to type the descriptive name when referring to
+the function.  Thus, in an init file, one might find
+
+@example
+Meta-Rubout:	backward-kill-word
+@end example
+
+This binds the keystroke @key{Meta-Rubout} to the function
+@emph{descriptively} named @code{backward-kill-word}.  You, as the
+programmer, should bind the functions you write to descriptive names as
+well.  Readline provides a function for doing that:
+
+@deftypefun int rl_add_defun (const char *name, rl_command_func_t *function, int key)
+Add @var{name} to the list of named functions.  Make @var{function} be
+the function that gets called.  If @var{key} is not -1, then bind it to
+@var{function} using @code{rl_bind_key()}.
+@end deftypefun
+
+Using this function alone is sufficient for most applications.
+It is the recommended way to add a few functions to the default
+functions that Readline has built in.
+If you need to do something other than adding a function to Readline,
+you may need to use the underlying functions described below.
+
+@node Keymaps
+@subsection Selecting a Keymap
+
+Key bindings take place on a @dfn{keymap}.  The keymap is the
+association between the keys that the user types and the functions that
+get run.  You can make your own keymaps, copy existing keymaps, and tell
+Readline which keymap to use.
+
+@deftypefun Keymap rl_make_bare_keymap (void)
+Returns a new, empty keymap.  The space for the keymap is allocated with
+@code{malloc()}; the caller should free it by calling
+@code{rl_discard_keymap()} when done.
+@end deftypefun
+
+@deftypefun Keymap rl_copy_keymap (Keymap map)
+Return a new keymap which is a copy of @var{map}.
+@end deftypefun
+
+@deftypefun Keymap rl_make_keymap (void)
+Return a new keymap with the printing characters bound to rl_insert,
+the lowercase Meta characters bound to run their equivalents, and
+the Meta digits bound to produce numeric arguments.
+@end deftypefun
+
+@deftypefun void rl_discard_keymap (Keymap keymap)
+Free the storage associated with @var{keymap}.
+@end deftypefun
+
+Readline has several internal keymaps.  These functions allow you to
+change which keymap is active.
+
+@deftypefun Keymap rl_get_keymap (void)
+Returns the currently active keymap.
+@end deftypefun
+
+@deftypefun void rl_set_keymap (Keymap keymap)
+Makes @var{keymap} the currently active keymap.
+@end deftypefun
+
+@deftypefun Keymap rl_get_keymap_by_name (const char *name)
+Return the keymap matching @var{name}.  @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun {char *} rl_get_keymap_name (Keymap keymap)
+Return the name matching @var{keymap}.  @var{name} is one which would
+be supplied in a @code{set keymap} inputrc line (@pxref{Readline Init File}).
+@end deftypefun
+
+@node Binding Keys
+@subsection Binding Keys
+
+Key sequences are associate with functions through the keymap.
+Readline has several internal keymaps: @code{emacs_standard_keymap},
+@code{emacs_meta_keymap}, @code{emacs_ctlx_keymap},
+@code{vi_movement_keymap}, and @code{vi_insertion_keymap}.
+@code{emacs_standard_keymap} is the default, and the examples in
+this manual assume that.
+
+Since @code{readline()} installs a set of default key bindings the first
+time it is called, there is always the danger that a custom binding
+installed before the first call to @code{readline()} will be overridden.
+An alternate mechanism is to install custom key bindings in an
+initialization function assigned to the @code{rl_startup_hook} variable
+(@pxref{Readline Variables}).
+
+These functions manage key bindings.
+
+@deftypefun int rl_bind_key (int key, rl_command_func_t *function)
+Binds @var{key} to @var{function} in the currently active keymap.
+Returns non-zero in the case of an invalid @var{key}.

+@deftypefun int rl_bind_key_if_unbound (int key, rl_command_func_t *function)
+Binds @var{key} to @var{function} if it is not already bound in the
+currently active keymap.
+Returns non-zero in the case of an invalid @var{key} or if @var{key} is
+already bound.
+@end deftypefun
+
+@deftypefun int rl_bind_key_if_unbound_in_map (int key, rl_command_func_t *function, Keymap map)
+Binds @var{key} to @var{function} if it is not already bound in @var{map}.
+Returns non-zero in the case of an invalid @var{key} or if @var{key} is
+already bound.
+@end deftypefun
+
+@deftypefun int rl_unbind_key (int key)
+Bind @var{key} to the null function in the currently active keymap.
+Returns non-zero in case of error.
+@end deftypefun
+
+@deftypefun int rl_unbind_key_in_map (int key, Keymap map)
+Bind @var{key} to the null function in @var{map}.
+Returns non-zero in case of error.
+@end deftypefun
+
+@deftypefun int rl_unbind_function_in_map (rl_command_func_t *function, Keymap map)
+Unbind all keys that execute @var{function} in @var{map}.
+@end deftypefun
+
+@deftypefun int rl_unbind_command_in_map (const char *command, Keymap map)
+Unbind all keys that are bound to @var{command} in @var{map}.
+@end deftypefun
+
+@deftypefun int rl_bind_keyseq (const char *keyseq, rl_command_func_t *function)
+Bind the key sequence represented by the string @var{keyseq} to the function
+@var{function}, beginning in the current keymap.
+This makes new keymaps as necessary.
+The return value is non-zero if @var{keyseq} is invalid.
+@end deftypefun
+
+@deftypefun int rl_bind_keyseq_in_map (const char *keyseq, rl_command_func_t *function, Keymap map)
+Bind the key sequence represented by the string @var{keyseq} to the function
+@var{function}.  This makes new keymaps as necessary.
+Initial bindings are performed in @var{map}.
+The return value is non-zero if @var{keyseq} is invalid.
+@end deftypefun
+
+@deftypefun int rl_set_key (const char *keyseq, rl_command_func_t *function, Keymap map)

+@end deftypefun
+
+@deftypefun int rl_bind_keyseq_if_unbound_in_map (const char *keyseq, rl_command_func_t *function, Keymap map)

+@end deftypefun
+
+@deftypefun int rl_generic_bind (int type, const char *keyseq, char *data, Keymap map)
+Bind the key sequence represented by the string @var{keyseq} to the arbitrary
+pointer @var{data}.  @var{type} says what kind of data is pointed to by
+@var{data}; this can be a function (@code{ISFUNC}), a macro
+(@code{ISMACR}), or a keymap (@code{ISKMAP}).  This makes new keymaps as
+necessary.  The initial keymap in which to do bindings is @var{map}.
+@end deftypefun
+
+@deftypefun int rl_parse_and_bind (char *line)
+Parse @var{line} as if it had been read from the @code{inputrc} file and
+perform any key bindings and variable assignments found
+(@pxref{Readline Init File}).
+@end deftypefun
+
+@deftypefun int rl_read_init_file (const char *filename)

+@node Associating Function Names and Bindings
+@subsection Associating Function Names and Bindings
+
+These functions allow you to find out what keys invoke named functions
+and the functions invoked by a particular key sequence.  You may also

+
+@deftypefun {rl_command_func_t *} rl_function_of_keyseq (const char *keyseq, Keymap map, int *type)
+Return the function invoked by @var{keyseq} in keymap @var{map}.
+If @var{map} is @code{NULL}, the current keymap is used.  If @var{type} is
+not @code{NULL}, the type of the object is returned in the @code{int} variable

+@end deftypefun
+
+@deftypefun {char **} rl_invoking_keyseqs (rl_command_func_t *function)

+@end deftypefun
+
+@deftypefun {char **} rl_invoking_keyseqs_in_map (rl_command_func_t *function, Keymap map)
+Return an array of strings representing the key sequences used to

+@end deftypefun
+
+@deftypefun void rl_function_dumper (int readable)
+Print the readline function names and the key sequences currently
+bound to them to @code{rl_outstream}.  If @var{readable} is non-zero,

+Print the names of all bindable Readline functions to @code{rl_outstream}.
+@end deftypefun
+
+@deftypefun {const char **} rl_funmap_names (void)
+Return a NULL terminated array of known function names.  The array is

+@end deftypefun
+
+@deftypefun int rl_add_funmap_entry (const char *name, rl_command_func_t *function)
+Add @var{name} to the list of bindable Readline command names, and make
+@var{function} the function to be called when @var{name} is invoked.
+@end deftypefun
+
+@node Allowing Undoing
+@subsection Allowing Undoing
+
+Supporting the undo command is a painless thing, and makes your
+functions much more useful.  It is certainly easy to try
+something if you know you can undo it.
+
+If your function simply inserts text once, or deletes text once, and
+uses @code{rl_insert_text()} or @code{rl_delete_text()} to do it, then
+undoing is already done for you automatically.
+
+If you do multiple insertions or multiple deletions, or any combination
+of these operations, you should group them together into one operation.
+This is done with @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+The types of events that can be undone are:
+
+@smallexample
+enum undo_code @{ UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END @}; 
+@end smallexample
+
+Notice that @code{UNDO_DELETE} means to insert some text, and
+@code{UNDO_INSERT} means to delete some text.  That is, the undo code
+tells what to undo, not how to undo it.  @code{UNDO_BEGIN} and
+@code{UNDO_END} are tags added by @code{rl_begin_undo_group()} and
+@code{rl_end_undo_group()}.
+
+@deftypefun int rl_begin_undo_group (void)
+Begins saving undo information in a group construct.  The undo
+information usually comes from calls to @code{rl_insert_text()} and
+@code{rl_delete_text()}, but could be the result of calls to
+@code{rl_add_undo()}.
+@end deftypefun
+
+@deftypefun int rl_end_undo_group (void)
+Closes the current undo group started with @code{rl_begin_undo_group
+()}.  There should be one call to @code{rl_end_undo_group()}
+for each call to @code{rl_begin_undo_group()}.
+@end deftypefun
+
+@deftypefun void rl_add_undo (enum undo_code what, int start, int end, char *text)
+Remember how to undo an event (according to @var{what}).  The affected
+text runs from @var{start} to @var{end}, and encompasses @var{text}.
+@end deftypefun
+
+@deftypefun void rl_free_undo_list (void)
+Free the existing undo list.
+@end deftypefun
+
+@deftypefun int rl_do_undo (void)
+Undo the first thing on the undo list.  Returns @code{0} if there was
+nothing to undo, non-zero if something was undone.
+@end deftypefun
+
+Finally, if you neither insert nor delete text, but directly modify the
+existing text (e.g., change its case), call @code{rl_modifying()}
+once, just before you modify the text.  You must supply the indices of
+the text range that you are going to modify.
+
+@deftypefun int rl_modifying (int start, int end)
+Tell Readline to save the text between @var{start} and @var{end} as a
+single undo unit.  It is assumed that you will subsequently modify
+that text.
+@end deftypefun
+
+@node Redisplay
+@subsection Redisplay
+
+@deftypefun void rl_redisplay (void)
+Change what's displayed on the screen to reflect the current contents
+of @code{rl_line_buffer}.
+@end deftypefun

+Force the line to be updated and redisplayed, whether or not
+Readline thinks the screen display is correct.
+@end deftypefun
+
+@deftypefun int rl_on_new_line (void)
+Tell the update functions that we have moved onto a new (empty) line,
+usually after ouputting a newline.
+@end deftypefun
+
+@deftypefun int rl_on_new_line_with_prompt (void)
+Tell the update functions that we have moved onto a new line, with
+@var{rl_prompt} already displayed.
+This could be used by applications that want to output the prompt string
+themselves, but still need Readline to know the prompt string length for
+redisplay.
+It should be used after setting @var{rl_already_prompted}.

+
+@deftypefun int rl_reset_line_state (void)
+Reset the display state to a clean state and redisplay the current line
+starting on a new line.

+
+@deftypefun int rl_crlf (void)
+Move the cursor to the start of the next screen line.
+@end deftypefun
+
+@deftypefun int rl_show_char (int c)
+Display character @var{c} on @code{rl_outstream}.
+If Readline has not been set to display meta characters directly, this
+will convert meta characters to a meta-prefixed key sequence.
+This is intended for use by applications which wish to do their own
+redisplay.
+@end deftypefun
+
+@deftypefun int rl_message (const char *, @dots{})
+The arguments are a format string as would be supplied to @code{printf},
+possibly containing conversion specifications such as @samp{%d}, and
+any additional arguments necessary to satisfy the conversion specifications.
+The resulting string is displayed in the @dfn{echo area}.  The echo area
+is also used to display numeric arguments and search strings.
+You should call @code{rl_save_prompt} to save the prompt information
+before calling this function.
+@end deftypefun
+
+@deftypefun int rl_clear_message (void)
+Clear the message in the echo area.  If the prompt was saved with a call to

+call @code{rl_restore_prompt} before calling this function.
+@end deftypefun

+@end deftypefun
+
+@deftypefun void rl_restore_prompt (void)
+Restore the local Readline prompt display state saved by the most
+recent call to @code{rl_save_prompt}.
+if @code{rl_save_prompt} was called to save the prompt before a call
+to @code{rl_message}, this function should be called before the
+corresponding call to @code{rl_clear_message}.
+@end deftypefun
+
+@deftypefun int rl_expand_prompt (char *prompt)
+Expand any special character sequences in @var{prompt} and set up the

+This function is called by @code{readline()}.  It may also be called to
+expand the primary prompt if the @code{rl_on_new_line_with_prompt()}
+function or @code{rl_already_prompted} variable is used.
+It returns the number of visible characters on the last line of the
+(possibly multi-line) prompt.
+Applications may indicate that the prompt contains characters that take
+up no physical screen space when displayed by bracketing a sequence of
+such characters with the special markers @code{RL_PROMPT_START_IGNORE}
+and @code{RL_PROMPT_END_IGNORE} (declared in @file{readline.h}.  This may
+be used to embed terminal-specific escape sequences in prompts.
+@end deftypefun
+
+@deftypefun int rl_set_prompt (const char *prompt)
+Make Readline use @var{prompt} for subsequent redisplay.  This calls

+@node Alternate Interface
+@subsection Alternate Interface
+
+An alternate interface is available to plain @code{readline()}.  Some
+applications need to interleave keyboard I/O with file, device, or
+window system I/O, typically by using a main loop to @code{select()}
+on various file descriptors.  To accomodate this need, readline can
+also be invoked as a `callback' function from an event loop.  There
+are functions available to make this easy.
+
+@deftypefun void rl_callback_handler_install (const char *prompt, rl_vcpfunc_t *lhandler)
+Set up the terminal for readline I/O and display the initial
+expanded value of @var{prompt}.  Save the value of @var{lhandler} to
+use as a function to call when a complete line of input has been entered.
+The function takes the text of the line as an argument.
+@end deftypefun
+
+@deftypefun void rl_callback_read_char (void)
+Whenever an application determines that keyboard input is available, it
+should call @code{rl_callback_read_char()}, which will read the next
+character from the current input source.
+If that character completes the line, @code{rl_callback_read_char} will
+invoke the @var{lhandler} function saved by @code{rl_callback_handler_install}
+to process the line.
+Before calling the @var{lhandler} function, the terminal settings are
+reset to the values they had before calling
+@code{rl_callback_handler_install}.
+If the @var{lhandler} function returns,
+the terminal settings are modified for Readline's use again.
+@code{EOF} is  indicated by calling @var{lhandler} with a
+@code{NULL} line.
+@end deftypefun
+
+@deftypefun void rl_callback_handler_remove (void)
+Restore the terminal to its initial state and remove the line handler.
+This may be called from within a callback as well as independently.
+If the @var{lhandler} installed by @code{rl_callback_handler_install}
+does not exit the program, either this function or the function referred
+to by the value of @code{rl_deprep_term_function} should be called before

+@node Readline Signal Handling
+@section Readline Signal Handling
+
+Signals are asynchronous events sent to a process by the Unix kernel,
+sometimes on behalf of another process.  They are intended to indicate
+exceptional events, like a user pressing the interrupt key on his terminal,
+or a network connection being broken.  There is a class of signals that can
+be sent to the process currently reading input from the keyboard.  Since
+Readline changes the terminal attributes when it is called, it needs to
+perform special processing when such a signal is received in order to
+restore the terminal to a sane state, or provide application writers with
+functions to do so manually. 
+
+Readline contains an internal signal handler that is installed for a
+number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM},
+@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}).
+When one of these signals is received, the signal handler
+will reset the terminal attributes to those that were in effect before
+@code{readline()} was called, reset the signal handling to what it was
+before @code{readline()} was called, and resend the signal to the calling
+application.
+If and when the calling application's signal handler returns, Readline
+will reinitialize the terminal and continue to accept input.
+When a @code{SIGINT} is received, the Readline signal handler performs
+some additional work, which will cause any partially-entered line to be
+aborted (see the description of @code{rl_free_line_state()} below).
+
+There is an additional Readline signal handler, for @code{SIGWINCH}, which
+the kernel sends to a process whenever the terminal's size changes (for
+example, if a user resizes an @code{xterm}).  The Readline @code{SIGWINCH}
+handler updates Readline's internal screen size information, and then calls
+any @code{SIGWINCH} signal handler the calling application has installed. 
+Readline calls the application's @code{SIGWINCH} signal handler without
+resetting the terminal to its original state.  If the application's signal
+handler does more than update its idea of the terminal size and return (for
+example, a @code{longjmp} back to a main processing loop), it @emph{must}
+call @code{rl_cleanup_after_signal()} (described below), to restore the
+terminal state. 
+
+Readline provides two variables that allow application writers to
+control whether or not it will catch certain signals and act on them
+when they are received.  It is important that applications change the
+values of these variables only when calling @code{readline()}, not in
+a signal handler, so Readline's internal signal state is not corrupted.
+
+@deftypevar int rl_catch_signals
+If this variable is non-zero, Readline will install signal handlers for
+@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGALRM},
+@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}.
+
+The default value of @code{rl_catch_signals} is 1.
+@end deftypevar
+
+@deftypevar int rl_catch_sigwinch
+If this variable is non-zero, Readline will install a signal handler for
+@code{SIGWINCH}.
+
+The default value of @code{rl_catch_sigwinch} is 1.
+@end deftypevar
+
+If an application does not wish to have Readline catch any signals, or
+to handle signals other than those Readline catches (@code{SIGHUP},
+for example), 
+Readline provides convenience functions to do the necessary terminal
+and internal state cleanup upon receipt of a signal.
+
+@deftypefun void rl_cleanup_after_signal (void)
+This function will reset the state of the terminal to what it was before
+@code{readline()} was called, and remove the Readline signal handlers for
+all signals, depending on the values of @code{rl_catch_signals} and
+@code{rl_catch_sigwinch}.
+@end deftypefun
+
+@deftypefun void rl_free_line_state (void)
+This will free any partial state associated with the current input line
+(undo information, any partial history entry, any partially-entered
+keyboard macro, and any partially-entered numeric argument).  This
+should be called before @code{rl_cleanup_after_signal()}.  The
+Readline signal handler for @code{SIGINT} calls this to abort the
+current input line.
+@end deftypefun
+
+@deftypefun void rl_reset_after_signal (void)
+This will reinitialize the terminal and reinstall any Readline signal
+handlers, depending on the values of @code{rl_catch_signals} and
+@code{rl_catch_sigwinch}.
+@end deftypefun
+
+If an application does not wish Readline to catch @code{SIGWINCH}, it may
+call @code{rl_resize_terminal()} or @code{rl_set_screen_size()} to force
+Readline to update its idea of the terminal size when a @code{SIGWINCH}
+is received.
+
+@deftypefun void rl_resize_terminal (void)
+Update Readline's internal screen size by reading values from the kernel.
+@end deftypefun
+
+@deftypefun void rl_set_screen_size (int rows, int cols)
+Set Readline's idea of the terminal size to @var{rows} rows and
+@var{cols} columns.  If either @var{rows} or @var{columns} is less than
+or equal to 0, Readline's idea of that terminal dimension is unchanged.
+@end deftypefun
+
+If an application does not want to install a @code{SIGWINCH} handler, but
+is still interested in the screen dimensions, Readline's idea of the screen
+size may be queried.
+
+@deftypefun void rl_get_screen_size (int *rows, int *cols)
+Return Readline's idea of the terminal's size in the
+variables pointed to by the arguments.
+@end deftypefun
+
+@deftypefun void rl_reset_screen_size (void)
+Cause Readline to reobtain the screen size and recalculate its dimensions.

+@node How Completing Works
+@subsection How Completing Works
+
+In order to complete some text, the full list of possible completions
+must be available.  That is, it is not possible to accurately
+expand a partial word without knowing all of the possible words
+which make sense in that context.  The Readline library provides
+the user interface to completion, and two of the most common
+completion functions:  filename and username.  For completing other types
+of text, you must write your own completion function.  This section
+describes exactly what such functions must do, and provides an example.
+
+There are three major functions used to perform completion:
+
+@enumerate
+@item
+The user-interface function @code{rl_complete()}.  This function is
+called with the same arguments as other bindable Readline functions:
+@var{count} and @var{invoking_key}.
+It isolates the word to be completed and calls
+@code{rl_completion_matches()} to generate a list of possible completions.
+It then either lists the possible completions, inserts the possible
+completions, or actually performs the
+completion, depending on which behavior is desired.
+
+@item
+The internal function @code{rl_completion_matches()} uses an
+application-supplied @dfn{generator} function to generate the list of
+possible matches, and then returns the array of these matches.
+The caller should place the address of its generator function in
+@code{rl_completion_entry_function}.
+
+@item
+The generator function is called repeatedly from
+@code{rl_completion_matches()}, returning a string each time.  The
+arguments to the generator function are @var{text} and @var{state}.
+@var{text} is the partial word to be completed.  @var{state} is zero the
+first time the function is called, allowing the generator to perform
+any necessary initialization, and a positive non-zero integer for
+each subsequent call.  The generator function returns
+@code{(char *)NULL} to inform @code{rl_completion_matches()} that there are
+no more possibilities left.  Usually the generator function computes the
+list of possible completions when @var{state} is zero, and returns them
+one at a time on subsequent calls.  Each string the generator function
+returns as a match must be allocated with @code{malloc()}; Readline
+frees the strings when it has finished with them.
+Such a generator function is referred to as an
+@dfn{application-specific completion function}.
+
+@end enumerate
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()}).  The default is to do filename completion.
+@end deftypefun
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+This is a pointer to the generator function for
+@code{rl_completion_matches()}.
+If the value of @code{rl_completion_entry_function} is
+@code{NULL} then the default filename generator
+function, @code{rl_filename_completion_function()}, is used.
+An @dfn{application-specific completion function} is a function whose
+address is assigned to @code{rl_completion_entry_function} and whose
+return values are used to  generate possible completions.
+@end deftypevar
+
+@node Completion Functions
+@subsection Completion Functions
+
+Here is the complete list of callable completion functions present in
+Readline.
+
+@deftypefun int rl_complete_internal (int what_to_do)
+Complete the word at or before point.  @var{what_to_do} says what to do
+with the completion.  A value of @samp{?} means list the possible
+completions.  @samp{TAB} means do standard completion.  @samp{*} means
+insert all of the possible completions.  @samp{!} means to display
+all of the possible completions, if there is more than one, as well as
+performing partial completion.  @samp{@@} is similar to @samp{!}, but
+possible completions are not listed if the possible completions share
+a common prefix.
+@end deftypefun
+
+@deftypefun int rl_complete (int ignore, int invoking_key)
+Complete the word at or before point.  You have supplied the function
+that does the initial simple matching selection algorithm (see
+@code{rl_completion_matches()} and @code{rl_completion_entry_function}).
+The default is to do filename
+completion.  This calls @code{rl_complete_internal()} with an
+argument depending on @var{invoking_key}.
+@end deftypefun
+
+@deftypefun int rl_possible_completions (int count, int invoking_key)
+List the possible completions.  See description of @code{rl_complete
+()}.  This calls @code{rl_complete_internal()} with an argument of
+@samp{?}.
+@end deftypefun
+
+@deftypefun int rl_insert_completions (int count, int invoking_key)
+Insert the list of possible completions into the line, deleting the
+partially-completed word.  See description of @code{rl_complete()}.
+This calls @code{rl_complete_internal()} with an argument of @samp{*}.
+@end deftypefun
+
+@deftypefun int rl_completion_mode (rl_command_func_t *cfunc)
+Returns the apppriate value to pass to @code{rl_complete_internal()}
+depending on whether @var{cfunc} was called twice in succession and
+the values of the @code{show-all-if-ambiguous} and
+@code{show-all-if-unmodified} variables.
+Application-specific completion functions may use this function to present
+the same interface as @code{rl_complete()}.
+@end deftypefun
+
+@deftypefun {char **} rl_completion_matches (const char *text, rl_compentry_func_t *entry_func)
+Returns an array of strings which is a list of completions for
+@var{text}.  If there are no completions, returns @code{NULL}.
+The first entry in the returned array is the substitution for @var{text}.
+The remaining entries are the possible completions.  The array is
+terminated with a @code{NULL} pointer.
+
+@var{entry_func} is a function of two args, and returns a
+@code{char *}.  The first argument is @var{text}.  The second is a
+state argument; it is zero on the first call, and non-zero on subsequent
+calls.  @var{entry_func} returns a @code{NULL}  pointer to the caller
+when there are no more matches.
+@end deftypefun
+
+@deftypefun {char *} rl_filename_completion_function (const char *text, int state)
+A generator function for filename completion in the general case.
+@var{text} is a partial filename.
+The Bash source is a useful reference for writing application-specific
+completion functions (the Bash completion functions call this and other
+Readline functions).
+@end deftypefun
+
+@deftypefun {char *} rl_username_completion_function (const char *text, int state)
+A completion generator for usernames.  @var{text} contains a partial
+username preceded by a random character (usually @samp{~}).  As with all
+completion generators, @var{state} is zero on the first call and non-zero
+for subsequent calls.
+@end deftypefun
+
+@node Completion Variables
+@subsection Completion Variables
+
+@deftypevar {rl_compentry_func_t *} rl_completion_entry_function
+A pointer to the generator function for @code{rl_completion_matches()}.
+@code{NULL} means to use @code{rl_filename_completion_function()},
+the default filename completer.
+@end deftypevar
+
+@deftypevar {rl_completion_func_t *} rl_attempted_completion_function
+A pointer to an alternative function to create matches.
+The function is called with @var{text}, @var{start}, and @var{end}.
+@var{start} and @var{end} are indices in @code{rl_line_buffer} defining
+the boundaries of @var{text}, which is a character string.
+If this function exists and returns @code{NULL}, or if this variable is
+set to @code{NULL}, then @code{rl_complete()} will call the value of
+@code{rl_completion_entry_function} to generate matches, otherwise the
+array of strings returned will be used.
+If this function sets the @code{rl_attempted_completion_over}
+variable to a non-zero value, Readline will not perform its default
+completion even if this function returns no matches.
+@end deftypevar
+
+@deftypevar {rl_quote_func_t *} rl_filename_quoting_function
+A pointer to a function that will quote a filename in an
+application-specific fashion.  This is called if filename completion is being
+attempted and one of the characters in @code{rl_filename_quote_characters}
+appears in a completed filename.  The function is called with
+@var{text}, @var{match_type}, and @var{quote_pointer}.  The @var{text}
+is the filename to be quoted.  The @var{match_type} is either
+@code{SINGLE_MATCH}, if there is only one completion match, or
+@code{MULT_MATCH}.  Some functions use this to decide whether or not to
+insert a closing quote character.  The @var{quote_pointer} is a pointer
+to any opening quote character the user typed.  Some functions choose
+to reset this character.
+@end deftypevar
+
+@deftypevar {rl_dequote_func_t *} rl_filename_dequoting_function
+A pointer to a function that will remove application-specific quoting
+characters from a filename before completion is attempted, so those
+characters do not interfere with matching the text against names in
+the filesystem.  It is called with @var{text}, the text of the word
+to be dequoted, and @var{quote_char}, which is the quoting character 
+that delimits the filename (usually @samp{'} or @samp{"}).  If
+@var{quote_char} is zero, the filename was not in an embedded string.
+@end deftypevar
+
+@deftypevar {rl_linebuf_func_t *} rl_char_is_quoted_p
+A pointer to a function to call that determines whether or not a specific
+character in the line buffer is quoted, according to whatever quoting
+mechanism the program calling Readline uses.  The function is called with
+two arguments: @var{text}, the text of the line, and @var{index}, the
+index of the character in the line.  It is used to decide whether a
+character found in @code{rl_completer_word_break_characters} should be
+used to break words for the completer.
+@end deftypevar
+
+@deftypevar {rl_compignore_func_t *} rl_ignore_some_completions_function
+This function, if defined, is called by the completer when real filename
+completion is done, after all the matching names have been generated.
+It is passed a @code{NULL} terminated array of matches.
+The first element (@code{matches[0]}) is the
+maximal substring common to all matches. This function can
+re-arrange the list of matches as required, but each element deleted
+from the array must be freed.
+@end deftypevar
+
+@deftypevar {rl_icppfunc_t *} rl_directory_completion_hook
+This function, if defined, is allowed to modify the directory portion
+of filenames Readline completes.  It is called with the address of a
+string (the current directory name) as an argument, and may modify that string.
+If the string is replaced with a new string, the old value should be freed.
+Any modified directory name should have a trailing slash.
+The modified value will be displayed as part of the completion, replacing
+the directory portion of the pathname the user typed.
+It returns an integer that should be non-zero if the function modifies
+its directory argument.
+It could be used to expand symbolic links or shell variables in pathnames.
+@end deftypevar
+
+@deftypevar {rl_compdisp_func_t *} rl_completion_display_matches_hook
+If non-zero, then this is the address of a function to call when
+completing a word would normally display the list of possible matches.
+This function is called in lieu of Readline displaying the list.
+It takes three arguments:
+(@code{char **}@var{matches}, @code{int} @var{num_matches}, @code{int} @var{max_length})
+where @var{matches} is the array of matching strings,
+@var{num_matches} is the number of strings in that array, and
+@var{max_length} is the length of the longest string in that array.
+Readline provides a convenience function, @code{rl_display_match_list},
+that takes care of doing the display to Readline's output stream.  That
+function may be called from this hook.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_word_break_characters
+The basic list of characters that signal a break between words for the
+completer routine.  The default value of this variable is the characters
+which break words for completion in Bash:
+@code{" \t\n\"\\'`@@$><=;|&@{("}.
+@end deftypevar
+
+@deftypevar {const char *} rl_basic_quote_characters
+A list of quote characters which can cause a word break.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_word_break_characters
+The list of characters that signal a break between words for
+@code{rl_complete_internal()}.  The default list is the value of
+@code{rl_basic_word_break_characters}.
+@end deftypevar
+
+@deftypevar {rl_cpvfunc_t *} rl_completion_word_break_hook
+If non-zero, this is the address of a function to call when Readline is
+deciding where to separate words for word completion.  It should return
+a character string like @code{rl_completer_word_break_characters} to be
+used to perform the current completion.  The function may choose to set
+@code{rl_completer_word_break_characters} itself.  If the function
+returns @code{NULL}, @code{rl_completer_word_break_characters} is used.
+@end deftypevar
+
+@deftypevar {const char *} rl_completer_quote_characters
+A list of characters which can be used to quote a substring of the line.
+Completion occurs on the entire substring, and within the substring
+@code{rl_completer_word_break_characters} are treated as any other character,
+unless they also appear within this list.
+@end deftypevar
+
+@deftypevar {const char *} rl_filename_quote_characters
+A list of characters that cause a filename to be quoted by the completer
+when they appear in a completed filename.  The default is the null string.
+@end deftypevar
+
+@deftypevar {const char *} rl_special_prefixes
+The list of characters that are word break characters, but should be
+left in @var{text} when it is passed to the completion function.
+Programs can use this to help determine what kind of completing to do.
+For instance, Bash sets this variable to "$@@" so that it can complete
+shell variables and hostnames.
+@end deftypevar
+
+@deftypevar int rl_completion_query_items
+Up to this many items will be displayed in response to a
+possible-completions call.  After that, readline asks the user if she is sure
+she wants to see them all.  The default value is 100.  A negative value 
+indicates that Readline should never ask the user.
+@end deftypevar
+
+@deftypevar {int} rl_completion_append_character
+When a single completion alternative matches at the end of the command
+line, this character is appended to the inserted completion text.  The
+default is a space character (@samp{ }).  Setting this to the null
+character (@samp{\0}) prevents anything being appended automatically.
+This can be changed in application-specific completion functions to
+provide the ``most sensible word separator character'' according to
+an application-specific command line syntax specification.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_append
+If non-zero, @var{rl_completion_append_character} is not appended to
+matches at the end of the command line, as described above.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_quote_character
+When Readline is completing quoted text, as delimited by one of the
+characters in @var{rl_completer_quote_characters}, it sets this variable
+to the quoting character found.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_suppress_quote
+If non-zero, Readline does not append a matching quote character when
+performing completion on a quoted string.
+It is set to 0 before any application-specific completion function
+is called, and may only be changed within such a function.
+@end deftypevar
+
+@deftypevar int rl_completion_found_quote
+When Readline is completing quoted text, it sets this variable
+to a non-zero value if the word being completed contains or is delimited
+by any quoting characters, including backslashes.
+This is set before any application-specific completion function is called.
+@end deftypevar
+
+@deftypevar int rl_completion_mark_symlink_dirs
+If non-zero, a slash will be appended to completed filenames that are
+symbolic links to directory names, subject to the value of the
+user-settable @var{mark-directories} variable.
+This variable exists so that application-specific completion functions
+can override the user's global preference (set via the
+@var{mark-symlinked-directories} Readline variable) if appropriate.
+This variable is set to the user's preference before any
+application-specific completion function is called, so unless that
+function modifies the value, the user's preferences are honored.
+@end deftypevar
+
+@deftypevar int rl_ignore_completion_duplicates
+If non-zero, then duplicates in the matches are removed.
+The default is 1.
+@end deftypevar
+
+@deftypevar int rl_filename_completion_desired
+Non-zero means that the results of the matches are to be treated as
+filenames.  This is @emph{always} zero when completion is attempted,
+and can only be changed
+within an application-specific completion function.  If it is set to a
+non-zero value by such a function, directory names have a slash appended
+and Readline attempts to quote completed filenames if they contain any
+characters in @code{rl_filename_quote_characters} and
+@code{rl_filename_quoting_desired} is set to a non-zero value.
+@end deftypevar
+
+@deftypevar int rl_filename_quoting_desired
+Non-zero means that the results of the matches are to be quoted using
+double quotes (or an application-specific quoting mechanism) if the
+completed filename contains any characters in
+@code{rl_filename_quote_chars}.  This is @emph{always} non-zero
+when completion is attempted, and can only be changed within an
+application-specific completion function.
+The quoting is effected via a call to the function pointed to
+by @code{rl_filename_quoting_function}.
+@end deftypevar
+
+@deftypevar int rl_attempted_completion_over
+If an application-specific completion function assigned to
+@code{rl_attempted_completion_function} sets this variable to a non-zero
+value, Readline will not perform its default filename completion even
+if the application's completion function returns no matches.
+It should be set only by an application's completion function.
+@end deftypevar
+
+@deftypevar int rl_completion_type
+Set to a character describing the type of completion Readline is currently
+attempting; see the description of @code{rl_complete_internal()}
+(@pxref{Completion Functions}) for the list of characters.
+This is set to the appropriate value before any application-specific
+completion function is called, allowing such functions to present
+the same interface as @code{rl_complete()}.
+@end deftypevar
+
+@deftypevar int rl_inhibit_completion
+If this variable is non-zero, completion is inhibited.  The completion
+character will be inserted as any other bound to @code{self-insert}.
+@end deftypevar

+
+@node Introduction and Notation
+@section Introduction to Line Editing
+
+The following paragraphs describe the notation used to represent
+keystrokes.
+
+The text @kbd{C-k} is read as `Control-K' and describes the character
+produced when the @key{k} key is pressed while the Control key
+is depressed.
+
+The text @kbd{M-k} is read as `Meta-K' and describes the character
+produced when the Meta key (if you have one) is depressed, and the @key{k}
+key is pressed.
+The Meta key is labeled @key{ALT} on many keyboards.
+On keyboards with two keys labeled @key{ALT} (usually to either side of
+the space bar), the @key{ALT} on the left side is generally set to
+work as a Meta key.
+The @key{ALT} key on the right may also be configured to work as a
+Meta key or may be configured as some other modifier, such as a
+Compose key for typing accented characters.
+
+If you do not have a Meta or @key{ALT} key, or another key working as
+a Meta key, the identical keystroke can be generated by typing @key{ESC}
+@emph{first}, and then typing @key{k}.
+Either process is known as @dfn{metafying} the @key{k} key.
+
+The text @kbd{M-C-k} is read as `Meta-Control-k' and describes the
+character produced by @dfn{metafying} @kbd{C-k}.
+
+In addition, several keys have their own names.  Specifically,
+@key{DEL}, @key{ESC}, @key{LFD}, @key{SPC}, @key{RET}, and @key{TAB} all
+stand for themselves when seen in this text, or in an init file
+(@pxref{Readline Init File}).
+If your keyboard lacks a @key{LFD} key, typing @key{C-j} will
+produce the desired character.
+The @key{RET} key may be labeled @key{Return} or @key{Enter} on
+some keyboards.
+
+@node Readline Interaction
+@section Readline Interaction
+@cindex interaction, readline
+
+Often during an interactive session you type in a long line of text,
+only to notice that the first word on the line is misspelled.  The
+Readline library gives you a set of commands for manipulating the text
+as you type it in, allowing you to just fix your typo, and not forcing
+you to retype the majority of the line.  Using these editing commands,
+you move the cursor to the place that needs correction, and delete or
+insert the text of the corrections.  Then, when you are satisfied with
+the line, you simply press @key{RET}.  You do not have to be at the
+end of the line to press @key{RET}; the entire line is accepted
+regardless of the location of the cursor within the line.

+
+@node Readline Bare Essentials
+@subsection Readline Bare Essentials
+@cindex notation, readline
+@cindex command editing
+@cindex editing command lines
+
+In order to enter characters into the line, simply type them.  The typed
+character appears where the cursor was, and then the cursor moves one
+space to the right.  If you mistype a character, you can use your
+erase character to back up and delete the mistyped character.
+
+Sometimes you may mistype a character, and
+not notice the error until you have typed several other characters.  In
+that case, you can type @kbd{C-b} to move the cursor to the left, and then
+correct your mistake.  Afterwards, you can move the cursor to the right
+with @kbd{C-f}.
+
+When you add text in the middle of a line, you will notice that characters
+to the right of the cursor are `pushed over' to make room for the text
+that you have inserted.  Likewise, when you delete text behind the cursor,
+characters to the right of the cursor are `pulled back' to fill in the
+blank space created by the removal of the text.  A list of the bare
+essentials for editing the text of an input line follows.
+
+@table @asis
+@item @kbd{C-b}
+Move back one character.
+@item @kbd{C-f}
+Move forward one character.
+@item @key{DEL} or @key{Backspace}
+Delete the character to the left of the cursor.
+@item @kbd{C-d}
+Delete the character underneath the cursor.
+@item @w{Printing characters}
+Insert the character into the line at the cursor.
+@item @kbd{C-_} or @kbd{C-x C-u}
+Undo the last editing command.  You can undo all the way back to an
+empty line.
+@end table

+(Depending on your configuration, the @key{Backspace} key be set to
+delete the character to the left of the cursor and the @key{DEL} key set
+to delete the character underneath the cursor, like @kbd{C-d}, rather
+than the character to the left of the cursor.)
+
+@node Readline Movement Commands
+@subsection Readline Movement Commands
+
+
+The above table describes the most basic keystrokes that you need
+in order to do editing of the input line.  For your convenience, many
+other commands have been added in addition to @kbd{C-b}, @kbd{C-f},
+@kbd{C-d}, and @key{DEL}.  Here are some commands for moving more rapidly
+about the line.
+
+@table @kbd
+@item C-a
+Move to the start of the line.
+@item C-e
+Move to the end of the line.
+@item M-f
+Move forward a word, where a word is composed of letters and digits.
+@item M-b
+Move backward a word.
+@item C-l
+Clear the screen, reprinting the current line at the top.
+@end table
+
+Notice how @kbd{C-f} moves forward a character, while @kbd{M-f} moves
+forward a word.  It is a loose convention that control keystrokes
+operate on characters while meta keystrokes operate on words.
+
+@node Readline Killing Commands
+@subsection Readline Killing Commands
+
+@cindex killing text
+@cindex yanking text
+
+@dfn{Killing} text means to delete the text from the line, but to save
+it away for later use, usually by @dfn{yanking} (re-inserting)
+it back into the line.
+(`Cut' and `paste' are more recent jargon for `kill' and `yank'.)
+
+If the description for a command says that it `kills' text, then you can
+be sure that you can get the text back in a different (or the same)
+place later.
+
+When you use a kill command, the text is saved in a @dfn{kill-ring}.
+Any number of consecutive kills save all of the killed text together, so
+that when you yank it back, you get it all.  The kill
+ring is not line specific; the text that you killed on a previously
+typed line is available to be yanked back later, when you are typing
+another line.
+@cindex kill ring
+
+Here is the list of commands for killing text.
+
+@table @kbd
+@item C-k
+Kill the text from the current cursor position to the end of the line.
+
+@item M-d
+Kill from the cursor to the end of the current word, or, if between
+words, to the end of the next word.
+Word boundaries are the same as those used by @kbd{M-f}.
+
+@item M-@key{DEL}
+Kill from the cursor the start of the current word, or, if between
+words, to the start of the previous word.
+Word boundaries are the same as those used by @kbd{M-b}.
+
+@item C-w
+Kill from the cursor to the previous whitespace.  This is different than
+@kbd{M-@key{DEL}} because the word boundaries differ.
+
+@end table
+
+Here is how to @dfn{yank} the text back into the line.  Yanking
+means to copy the most-recently-killed text from the kill buffer.
+
+@table @kbd
+@item C-y
+Yank the most recently killed text back into the buffer at the cursor.
+
+@item M-y
+Rotate the kill-ring, and yank the new top.  You can only do this if
+the prior command is @kbd{C-y} or @kbd{M-y}.
+@end table
+
+@node Readline Arguments
+@subsection Readline Arguments
+
+You can pass numeric arguments to Readline commands.  Sometimes the
+argument acts as a repeat count, other times it is the @i{sign} of the
+argument that is significant.  If you pass a negative argument to a
+command which normally acts in a forward direction, that command will
+act in a backward direction.  For example, to kill text back to the
+start of the line, you might type @samp{M-- C-k}.
+
+The general way to pass numeric arguments to a command is to type meta
+digits before the command.  If the first `digit' typed is a minus
+sign (@samp{-}), then the sign of the argument will be negative.  Once
+you have typed one meta digit to get the argument started, you can type
+the remainder of the digits, and then the command.  For example, to give
+the @kbd{C-d} command an argument of 10, you could type @samp{M-1 0 C-d},
+which will delete the next ten characters on the input line.
+
+@node Searching
+@subsection Searching for Commands in the History
+
+Readline provides commands for searching through the command history
+@ifset BashFeatures
+(@pxref{Bash History Facilities})
+@end ifset
+for lines containing a specified string.
+There are two search modes:  @dfn{incremental} and @dfn{non-incremental}.
+
+Incremental searches begin before the user has finished typing the
+search string.
+As each character of the search string is typed, Readline displays
+the next entry from the history matching the string typed so far.
+An incremental search requires only as many characters as needed to
+find the desired history entry.
+To search backward in the history for a particular string, type
+@kbd{C-r}.  Typing @kbd{C-s} searches forward through the history.
+The characters present in the value of the @code{isearch-terminators} variable
+are used to terminate an incremental search.
+If that variable has not been assigned a value, the @key{ESC} and
+@kbd{C-J} characters will terminate an incremental search.
+@kbd{C-g} will abort an incremental search and restore the original line.
+When the search is terminated, the history entry containing the
+search string becomes the current line.
+
+To find other matching entries in the history list, type @kbd{C-r} or
+@kbd{C-s} as appropriate.
+This will search backward or forward in the history for the next
+entry matching the search string typed so far.
+Any other key sequence bound to a Readline command will terminate
+the search and execute that command.
+For instance, a @key{RET} will terminate the search and accept
+the line, thereby executing the command from the history list.
+A movement command will terminate the search, make the last line found
+the current line, and begin editing.
+
+Readline remembers the last incremental search string.  If two
+@kbd{C-r}s are typed without any intervening characters defining a new
+search string, any remembered search string is used.
+
+Non-incremental searches read the entire search string before starting
+to search for matching history lines.  The search string may be
+typed by the user or be part of the contents of the current line.
+
+@node Readline Init File
+@section Readline Init File
+@cindex initialization file, readline
+
+Although the Readline library comes with a set of Emacs-like
+keybindings installed by default, it is possible to use a different set
+of keybindings.
+Any user can customize programs that use Readline by putting
+commands in an @dfn{inputrc} file, conventionally in his home directory.
+The name of this
+@ifset BashFeatures
+file is taken from the value of the shell variable @env{INPUTRC}.  If
+@end ifset
+@ifclear BashFeatures
+file is taken from the value of the environment variable @env{INPUTRC}.  If
+@end ifclear
+that variable is unset, the default is @file{~/.inputrc}.
+
+When a program which uses the Readline library starts up, the
+init file is read, and the key bindings are set.
+
+In addition, the @code{C-x C-r} command re-reads this init file, thus
+incorporating any changes that you might have made to it.
+
+@menu
+* Readline Init File Syntax::	Syntax for the commands in the inputrc file.
+

+@end menu
+
+@node Readline Init File Syntax
+@subsection Readline Init File Syntax
+
+There are only a few basic constructs allowed in the
+Readline init file.  Blank lines are ignored.
+Lines beginning with a @samp{#} are comments.
+Lines beginning with a @samp{$} indicate conditional
+constructs (@pxref{Conditional Init Constructs}).  Other lines
+denote variable settings and key bindings.
+
+@table @asis
+@item Variable Settings
+You can modify the run-time behavior of Readline by
+altering the values of variables in Readline
+using the @code{set} command within the init file.
+The syntax is simple:
+
+@example
+set @var{variable} @var{value}
+@end example
+
+@noindent
+Here, for example, is how to
+change from the default Emacs-like key binding to use
+@code{vi} line editing commands:
+
+@example
+set editing-mode vi
+@end example
+
+Variable names and values, where appropriate, are recognized without regard
+to case.  Unrecognized variable names are ignored.
+
+Boolean variables (those that can be set to on or off) are set to on if
+the value is null or empty, @var{on} (case-insensitive), or 1.  Any other
+value results in the variable being set to off.
+
+@ifset BashFeatures
+The @w{@code{bind -V}} command lists the current Readline variable names
+and values.  @xref{Bash Builtins}.
+@end ifset
+
+A great deal of run-time behavior is changeable with the following
+variables.
+
+@cindex variables, readline
+@table @code
+
+@item bell-style
+@vindex bell-style
+Controls what happens when Readline wants to ring the terminal bell.
+If set to @samp{none}, Readline never rings the bell.  If set to
+@samp{visible}, Readline uses a visible bell if one is available.
+If set to @samp{audible} (the default), Readline attempts to ring
+the terminal's bell.
+
+@item bind-tty-special-chars
+@vindex bind-tty-special-chars
+If set to @samp{on}, Readline attempts to bind the control characters  
+treated specially by the kernel's terminal driver to their Readline
+equivalents.
+
+@item comment-begin
+@vindex comment-begin
+The string to insert at the beginning of the line when the
+@code{insert-comment} command is executed.  The default value
+is @code{"#"}.
+
+@item completion-ignore-case
+If set to @samp{on}, Readline performs filename matching and completion
+in a case-insensitive fashion.
+The default value is @samp{off}.
+
+@item completion-query-items
+@vindex completion-query-items
+The number of possible completions that determines when the user is
+asked whether the list of possibilities should be displayed.
+If the number of possible completions is greater than this value,
+Readline will ask the user whether or not he wishes to view
+them; otherwise, they are simply listed.
+This variable must be set to an integer value greater than or equal to 0.
+A negative value means Readline should never ask.
+The default limit is @code{100}.
+
+@item convert-meta
+@vindex convert-meta
+If set to @samp{on}, Readline will convert characters with the
+eighth bit set to an @sc{ascii} key sequence by stripping the eighth
+bit and prefixing an @key{ESC} character, converting them to a
+meta-prefixed key sequence.  The default value is @samp{on}.
+
+@item disable-completion
+@vindex disable-completion
+If set to @samp{On}, Readline will inhibit word completion.
+Completion  characters will be inserted into the line as if they had
+been mapped to @code{self-insert}.  The default is @samp{off}.
+
+@item editing-mode
+@vindex editing-mode
+The @code{editing-mode} variable controls which default set of
+key bindings is used.  By default, Readline starts up in Emacs editing
+mode, where the keystrokes are most similar to Emacs.  This variable can be
+set to either @samp{emacs} or @samp{vi}.
+
+@item enable-keypad
+@vindex enable-keypad
+When set to @samp{on}, Readline will try to enable the application
+keypad when it is called.  Some systems need this to enable the
+arrow keys.  The default is @samp{off}.
+
+@item expand-tilde
+@vindex expand-tilde
+If set to @samp{on}, tilde expansion is performed when Readline
+attempts word completion.  The default is @samp{off}.
+
+@item history-preserve-point
+@vindex history-preserve-point
+If set to @samp{on}, the history code attempts to place point at the
+same location on each history line retrieved with @code{previous-history}
+or @code{next-history}.  The default is @samp{off}.
+
+@item horizontal-scroll-mode
+@vindex horizontal-scroll-mode
+This variable can be set to either @samp{on} or @samp{off}.  Setting it
+to @samp{on} means that the text of the lines being edited will scroll
+horizontally on a single screen line when they are longer than the width
+of the screen, instead of wrapping onto a new screen line.  By default,
+this variable is set to @samp{off}.
+
+@item input-meta
+@vindex input-meta
+@vindex meta-flag
+If set to @samp{on}, Readline will enable eight-bit input (it
+will not clear the eighth bit in the characters it reads),
+regardless of what the terminal claims it can support.  The
+default value is @samp{off}.  The name @code{meta-flag} is a
+synonym for this variable.
+
+@item isearch-terminators
+@vindex isearch-terminators
+The string of characters that should terminate an incremental search without
+subsequently executing the character as a command (@pxref{Searching}).
+If this variable has not been given a value, the characters @key{ESC} and
+@kbd{C-J} will terminate an incremental search.
+
+@item keymap
+@vindex keymap
+Sets Readline's idea of the current keymap for key binding commands.
+Acceptable @code{keymap} names are
+@code{emacs},
+@code{emacs-standard},
+@code{emacs-meta},
+@code{emacs-ctlx},
+@code{vi},
+@code{vi-move},
+@code{vi-command}, and
+@code{vi-insert}.
+@code{vi} is equivalent to @code{vi-command}; @code{emacs} is
+equivalent to @code{emacs-standard}.  The default value is @code{emacs}.
+The value of the @code{editing-mode} variable also affects the
+default keymap.
+
+@item mark-directories
+If set to @samp{on}, completed directory names have a slash
+appended.  The default is @samp{on}.
+
+@item mark-modified-lines
+@vindex mark-modified-lines
+This variable, when set to @samp{on}, causes Readline to display an
+asterisk (@samp{*}) at the start of history lines which have been modified.
+This variable is @samp{off} by default.
+
+@item mark-symlinked-directories
+@vindex mark-symlinked-directories
+If set to @samp{on}, completed names which are symbolic links
+to directories have a slash appended (subject to the value of
+@code{mark-directories}).
+The default is @samp{off}.
+
+@item match-hidden-files
+@vindex match-hidden-files
+This variable, when set to @samp{on}, causes Readline to match files whose
+names begin with a @samp{.} (hidden files) when performing filename
+completion, unless the leading @samp{.} is
+supplied by the user in the filename to be completed.
+This variable is @samp{on} by default.
+
+@item output-meta
+@vindex output-meta
+If set to @samp{on}, Readline will display characters with the
+eighth bit set directly rather than as a meta-prefixed escape
+sequence.  The default is @samp{off}.
+
+@item page-completions
+@vindex page-completions
+If set to @samp{on}, Readline uses an internal @code{more}-like pager
+to display a screenful of possible completions at a time.
+This variable is @samp{on} by default.
+
+@item print-completions-horizontally
+If set to @samp{on}, Readline will display completions with matches
+sorted horizontally in alphabetical order, rather than down the screen.
+The default is @samp{off}.
+
+@item show-all-if-ambiguous
+@vindex show-all-if-ambiguous
+This alters the default behavior of the completion functions.  If
+set to @samp{on}, 
+words which have more than one possible completion cause the
+matches to be listed immediately instead of ringing the bell.
+The default value is @samp{off}.
+
+@item show-all-if-unmodified
+@vindex show-all-if-unmodified
+This alters the default behavior of the completion functions in
+a fashion similar to @var{show-all-if-ambiguous}.
+If set to @samp{on}, 
+words which have more than one possible completion without any
+possible partial completion (the possible completions don't share
+a common prefix) cause the matches to be listed immediately instead
+of ringing the bell.
+The default value is @samp{off}.
+
+@item visible-stats
+@vindex visible-stats
+If set to @samp{on}, a character denoting a file's type
+is appended to the filename when listing possible
+completions.  The default is @samp{off}.
+
+@end table
+
+@item Key Bindings
+The syntax for controlling key bindings in the init file is
+simple.  First you need to find the name of the command that you
+want to change.  The following sections contain tables of the command
+name, the default keybinding, if any, and a short description of what
+the command does.
+
+Once you know the name of the command, simply place on a line
+in the init file the name of the key
+you wish to bind the command to, a colon, and then the name of the
+command.  The name of the key
+can be expressed in different ways, depending on what you find most
+comfortable.
+
+In addition to command names, readline allows keys to be bound
+to a string that is inserted when the key is pressed (a @var{macro}).
+
+@ifset BashFeatures
+The @w{@code{bind -p}} command displays Readline function names and
+bindings in a format that can put directly into an initialization file.
+@xref{Bash Builtins}.
+@end ifset
+
+@table @asis
+@item @w{@var{keyname}: @var{function-name} or @var{macro}}
+@var{keyname} is the name of a key spelled out in English.  For example:
+@example
+Control-u: universal-argument
+Meta-Rubout: backward-kill-word
+Control-o: "> output"
+@end example
+
+In the above example, @kbd{C-u} is bound to the function
+@code{universal-argument},
+@kbd{M-DEL} is bound to the function @code{backward-kill-word}, and
+@kbd{C-o} is bound to run the macro
+expressed on the right hand side (that is, to insert the text
+@samp{> output} into the line).
+
+A number of symbolic character names are recognized while
+processing this key binding syntax:
+@var{DEL},
+@var{ESC},
+@var{ESCAPE},
+@var{LFD},
+@var{NEWLINE},
+@var{RET},
+@var{RETURN},
+@var{RUBOUT},
+@var{SPACE},
+@var{SPC},
+and
+@var{TAB}.
+
+@item @w{"@var{keyseq}": @var{function-name} or @var{macro}}
+@var{keyseq} differs from @var{keyname} above in that strings
+denoting an entire key sequence can be specified, by placing
+the key sequence in double quotes.  Some @sc{gnu} Emacs style key
+escapes can be used, as in the following example, but the
+special character names are not recognized.
+
+@example
+"\C-u": universal-argument
+"\C-x\C-r": re-read-init-file
+"\e[11~": "Function Key 1"
+@end example
+
+In the above example, @kbd{C-u} is again bound to the function
+@code{universal-argument} (just as it was in the first example),
+@samp{@kbd{C-x} @kbd{C-r}} is bound to the function @code{re-read-init-file},
+and @samp{@key{ESC} @key{[} @key{1} @key{1} @key{~}} is bound to insert
+the text @samp{Function Key 1}.
+
+@end table
+
+The following @sc{gnu} Emacs style escape sequences are available when
+specifying key sequences:
+
+@table @code
+@item @kbd{\C-}
+control prefix
+@item @kbd{\M-}
+meta prefix
+@item @kbd{\e}
+an escape character
+@item @kbd{\\}
+backslash
+@item @kbd{\"}
+@key{"}, a double quotation mark
+@item @kbd{\'}
+@key{'}, a single quote or apostrophe
+@end table
+
+In addition to the @sc{gnu} Emacs style escape sequences, a second
+set of backslash escapes is available:
+
+@table @code
+@item \a
+alert (bell)
+@item \b
+backspace
+@item \d
+delete
+@item \f
+form feed
+@item \n
+newline
+@item \r
+carriage return
+@item \t
+horizontal tab
+@item \v
+vertical tab
+@item \@var{nnn}
+the eight-bit character whose value is the octal value @var{nnn}
+(one to three digits)
+@item \x@var{HH}
+the eight-bit character whose value is the hexadecimal value @var{HH}
+(one or two hex digits)
+@end table
+
+When entering the text of a macro, single or double quotes must
+be used to indicate a macro definition.
+Unquoted text is assumed to be a function name.
+In the macro body, the backslash escapes described above are expanded.
+Backslash will quote any other character in the macro text,
+including @samp{"} and @samp{'}.
+For example, the following binding will make @samp{@kbd{C-x} \}
+insert a single @samp{\} into the line:
+@example
+"\C-x\\": "\\"
+@end example
+
+@end table
+
+@node Conditional Init Constructs
+@subsection Conditional Init Constructs
+
+Readline implements a facility similar in spirit to the conditional
+compilation features of the C preprocessor which allows key
+bindings and variable settings to be performed as the result
+of tests.  There are four parser directives used.
+
+@table @code
+@item $if
+The @code{$if} construct allows bindings to be made based on the
+editing mode, the terminal being used, or the application using
+Readline.  The text of the test extends to the end of the line;
+no characters are required to isolate it.
+
+@table @code
+@item mode
+The @code{mode=} form of the @code{$if} directive is used to test
+whether Readline is in @code{emacs} or @code{vi} mode.
+This may be used in conjunction
+with the @samp{set keymap} command, for instance, to set bindings in
+the @code{emacs-standard} and @code{emacs-ctlx} keymaps only if
+Readline is starting out in @code{emacs} mode.
+
+@item term
+The @code{term=} form may be used to include terminal-specific
+key bindings, perhaps to bind the key sequences output by the
+terminal's function keys.  The word on the right side of the
+@samp{=} is tested against both the full name of the terminal and
+the portion of the terminal name before the first @samp{-}.  This
+allows @code{sun} to match both @code{sun} and @code{sun-cmd},
+for instance.
+
+@item application
+The @var{application} construct is used to include
+application-specific settings.  Each program using the Readline
+library sets the @var{application name}, and you can test for
+a particular value. 
+This could be used to bind key sequences to functions useful for
+a specific program.  For instance, the following command adds a
+key sequence that quotes the current or previous word in Bash:
+@example
+$if Bash
+# Quote the current or previous word
+"\C-xq": "\eb\"\ef\""
+$endif
+@end example
+@end table
+
+@item $endif
+This command, as seen in the previous example, terminates an
+@code{$if} command.
+
+@item $else
+Commands in this branch of the @code{$if} directive are executed if
+the test fails.
+
+@item $include
+This directive takes a single filename as an argument and reads commands
+and bindings from that file.
+For example, the following directive reads from @file{/etc/inputrc}:
+@example
+$include /etc/inputrc
+@end example
+@end table
+
+@node Sample Init File
+@subsection Sample Init File

+Here is an example of an @var{inputrc} file.  This illustrates key
+binding, variable assignment, and conditional syntax.

+@node Commands For History
+@subsection Commands For Manipulating The History
+
+@ftable @code
+@item accept-line (Newline or Return)
+@ifset BashFeatures
+Accept the line regardless of where the cursor is.
+If this line is
+non-empty, add it to the history list according to the setting of
+the @env{HISTCONTROL} and @env{HISTIGNORE} variables.
+If this line is a modified history line, then restore the history line
+to its original state.
+@end ifset
+@ifclear BashFeatures
+Accept the line regardless of where the cursor is.
+If this line is
+non-empty, it may be added to the history list for future recall with
+@code{add_history()}.
+If this line is a modified history line, the history line is restored
+to its original state.
+@end ifclear
+
+@item previous-history (C-p)

+Move to the end of the input history, i.e., the line currently
+being entered.
+
+@item reverse-search-history (C-r)
+Search backward starting at the current line and moving `up' through
+the history as necessary.  This is an incremental search.
+
+@item forward-search-history (C-s)
+Search forward starting at the current line and moving `down' through
+the the history as necessary.  This is an incremental search.
+
+@item non-incremental-reverse-search-history (M-p)

+for a string supplied by the user.
+
+@item non-incremental-forward-search-history (M-n)
+Search forward starting at the current line and moving `down'
+through the the history as necessary using a non-incremental search
+for a string supplied by the user.
+
+@item history-search-forward ()
+Search forward through the history for the string of characters
+between the start of the current line and the point.
+This is a non-incremental search.
+By default, this command is unbound.
+
+@item history-search-backward ()
+Search backward through the history for the string of characters
+between the start of the current line and the point.  This
+is a non-incremental search.  By default, this command is unbound.
+
+@item yank-nth-arg (M-C-y)
+Insert the first argument to the previous command (usually
+the second word on the previous line) at point.
+With an argument @var{n},
+insert the @var{n}th word from the previous command (the words
+in the previous command begin with word 0).  A negative argument
+inserts the @var{n}th word from the end of the previous command.
+Once the argument @var{n} is computed, the argument is extracted
+as if the @samp{!@var{n}} history expansion had been specified.
+
+@item yank-last-arg (M-. or M-_)
+Insert last argument to the previous command (the last word of the
+previous history entry).  With an
+argument, behave exactly like @code{yank-nth-arg}.
+Successive calls to @code{yank-last-arg} move back through the history
+list, inserting the last argument of each line in turn.
+The history expansion facilities are used to extract the last argument,

+
+@node Commands For Text
+@subsection Commands For Changing Text
+
+@ftable @code
+@item delete-char (C-d)
+Delete the character at point.  If point is at the
+beginning of the line, there are no characters in the line, and
+the last character typed was not bound to @code{delete-char}, then
+return @sc{eof}.
+
+@item backward-delete-char (Rubout)
+Delete the character behind the cursor.  A numeric argument means
+to kill the characters instead of deleting them.
+
+@item forward-backward-delete-char ()
+Delete the character under the cursor, unless the cursor is at the
+end of the line, in which case the character behind the cursor is
+deleted.  By default, this is not bound to a key.
+
+@item quoted-insert (C-q or C-v)
+Add the next character typed to the line verbatim.  This is
+how to insert key sequences like @kbd{C-q}, for example.
+
+@ifclear BashFeatures
+@item tab-insert (M-@key{TAB})
+Insert a tab character.
+@end ifclear
+
+@item self-insert (a, b, A, 1, !, @dots{})
+Insert yourself.
+
+@item transpose-chars (C-t)
+Drag the character before the cursor forward over
+the character at the cursor, moving the
+cursor forward as well.  If the insertion point
+is at the end of the line, then this
+transposes the last two characters of the line.
+Negative arguments have no effect.
+
+@item transpose-words (M-t)
+Drag the word before point past the word after point,
+moving point past that word as well.
+If the insertion point is at the end of the line, this transposes
+the last two words on the line.
+
+@item upcase-word (M-u)
+Uppercase the current (or following) word.  With a negative argument,
+uppercase the previous word, but do not move the cursor.
+
+@item downcase-word (M-l)
+Lowercase the current (or following) word.  With a negative argument,
+lowercase the previous word, but do not move the cursor.
+
+@item capitalize-word (M-c)
+Capitalize the current (or following) word.  With a negative argument,
+capitalize the previous word, but do not move the cursor.
+
+@item overwrite-mode ()
+Toggle overwrite mode.  With an explicit positive numeric argument,
+switches to overwrite mode.  With an explicit non-positive numeric
+argument, switches to insert mode.  This command affects only
+@code{emacs} mode; @code{vi} mode does overwrite differently.
+Each call to @code{readline()} starts in insert mode.
+
+In overwrite mode, characters bound to @code{self-insert} replace
+the text at point rather than pushing the text to the right.
+Characters bound to @code{backward-delete-char} replace the character
+before point with a space.
+
+By default, this command is unbound.

+@node Commands For Killing
+@subsection Killing And Yanking
+
+@ftable @code
+
+@item kill-line (C-k)

+Kill all characters on the current line, no matter where point is.
+By default, this is unbound.
+
+@item kill-word (M-d)
+Kill from point to the end of the current word, or if between
+words, to the end of the next word.
+Word boundaries are the same as @code{forward-word}.
+
+@item backward-kill-word (M-@key{DEL})
+Kill the word behind point.
+Word boundaries are the same as @code{backward-word}.
+
+@item unix-word-rubout (C-w)
+Kill the word behind point, using white space as a word boundary.
+The killed text is saved on the kill-ring.
+
+@item unix-filename-rubout ()
+Kill the word behind point, using white space and the slash character
+as the word boundaries.
+The killed text is saved on the kill-ring.
+
+@item delete-horizontal-space ()
+Delete all spaces and tabs around point.  By default, this is unbound.
+
+@item kill-region ()
+Kill the text in the current region.
+By default, this command is unbound.
+
+@item copy-region-as-kill ()
+Copy the text in the region to the kill buffer, so it can be yanked
+right away.  By default, this command is unbound.
+
+@item copy-backward-word ()
+Copy the word before point to the kill buffer.
+The word boundaries are the same as @code{backward-word}.
+By default, this command is unbound.
+
+@item copy-forward-word ()
+Copy the word following point to the kill buffer.
+The word boundaries are the same as @code{forward-word}.
+By default, this command is unbound.
+
+@item yank (C-y)
+Yank the top of the kill ring into the buffer at point.
+
+@item yank-pop (M-y)
+Rotate the kill-ring, and yank the new top.  You can only do this if
+the prior command is @code{yank} or @code{yank-pop}.

+
+@node Numeric Arguments
+@subsection Specifying Numeric Arguments
+@ftable @code
+
+@item digit-argument (@kbd{M-0}, @kbd{M-1}, @dots{} @kbd{M--})
+Add this digit to the argument already accumulating, or start a new
+argument.  @kbd{M--} starts a negative argument.
+
+@item universal-argument ()
+This is another way to specify an argument.
+If this command is followed by one or more digits, optionally with a
+leading minus sign, those digits define the argument.
+If the command is followed by digits, executing @code{universal-argument}
+again ends the numeric argument, but is otherwise ignored.
+As a special case, if this command is immediately followed by a
+character that is neither a digit or minus sign, the argument count
+for the next command is multiplied by four.
+The argument count is initially one, so executing this function the
+first time makes the argument count four, a second time makes the
+argument count sixteen, and so on.
+By default, this is not bound to a key.

+@node Commands For Completion
+@subsection Letting Readline Type For You
+
+@ftable @code
+@item complete (@key{TAB})
+Attempt to perform completion on the text before point.
+The actual completion performed is application-specific.
+@ifset BashFeatures
+Bash attempts completion treating the text as a variable (if the
+text begins with @samp{$}), username (if the text begins with
+@samp{~}), hostname (if the text begins with @samp{@@}), or
+command (including aliases and functions) in turn.  If none

+
+@item menu-complete ()
+Similar to @code{complete}, but replaces the word to be completed
+with a single match from the list of possible completions.
+Repeated execution of @code{menu-complete} steps through the list
+of possible completions, inserting each match in turn.
+At the end of the list of completions, the bell is rung
+(subject to the setting of @code{bell-style})
+and the original text is restored.
+An argument of @var{n} moves @var{n} positions forward in the list
+of matches; a negative argument may be used to move backward

+This command is intended to be bound to @key{TAB}, but is unbound
+by default.
+
+@item delete-char-or-list ()
+Deletes the character under the cursor if not at the beginning or
+end of the line (like @code{delete-char}).

+List the possible completions of the text before point,
+treating it as a hostname.
+
+@item complete-command (M-!)
+Attempt completion on the text before point, treating
+it as a command name.  Command completion attempts to
+match the text against aliases, reserved words, shell
+functions, shell builtins, and finally executable filenames,
+in that order.
+
+@item possible-command-completions (C-x !)
+List the possible completions of the text before point,
+treating it as a command name.
+
+@item dynamic-complete-history (M-@key{TAB})

+@node Programmable Completion
+@section Programmable Completion
+@cindex programmable completion
+
+When word completion is attempted for an argument to a command for
+which a completion specification (a @var{compspec}) has been defined
+using the @code{complete} builtin (@pxref{Programmable Completion Builtins}),
+the programmable completion facilities are invoked. 
+
+First, the command name is identified.
+If a compspec has been defined for that command, the
+compspec is used to generate the list of possible completions for the word.
+If the command word is a full pathname, a compspec for the full
+pathname is searched for first.
+If no compspec is found for the full pathname, an attempt is made to
+find a compspec for the portion following the final slash.
+
+Once a compspec has been found, it is used to generate the list of
+matching words.
+If a compspec is not found, the default Bash completion
+described above (@pxref{Commands For Completion}) is performed.
+
+First, the actions specified by the compspec are used.
+Only matches which are prefixed by the word being completed are
+returned.
+When the @option{-f} or @option{-d} option is used for filename or
+directory name completion, the shell variable @env{FIGNORE} is
+used to filter the matches.
+@xref{Bash Variables}, for a description of @env{FIGNORE}.
+
+Any completions specified by a filename expansion pattern to the
+@option{-G} option are generated next.
+The words generated by the pattern need not match the word being completed.
+The @env{GLOBIGNORE} shell variable is not used to filter the matches,
+but the @env{FIGNORE} shell variable is used.
+
+Next, the string specified as the argument to the @option{-W} option
+is considered.
+The string is first split using the characters in the @env{IFS}
+special variable as delimiters.
+Shell quoting is honored.
+Each word is then expanded using
+brace expansion, tilde expansion, parameter and variable expansion,
+command substitution, and arithmetic expansion,
+as described above (@pxref{Shell Expansions}).
+The results are split using the rules described above
+(@pxref{Word Splitting}).
+The results of the expansion are prefix-matched against the word being
+completed, and the matching words become the possible completions.
+
+After these matches have been generated, any shell function or command
+specified with the @option{-F} and @option{-C} options is invoked.
+When the command or function is invoked, the @env{COMP_LINE} and
+@env{COMP_POINT} variables are assigned values as described above
+(@pxref{Bash Variables}).
+If a shell function is being invoked, the @env{COMP_WORDS} and
+@env{COMP_CWORD} variables are also set.
+When the function or command is invoked, the first argument is the
+name of the command whose arguments are being completed, the
+second argument is the word being completed, and the third argument
+is the word preceding the word being completed on the current command line.
+No filtering of the generated completions against the word being completed
+is performed; the function or command has complete freedom in generating
+the matches.
+
+Any function specified with @option{-F} is invoked first.
+The function may use any of the shell facilities, including the
+@code{compgen} builtin described below
+(@pxref{Programmable Completion Builtins}), to generate the matches.
+It must put the possible completions in the @env{COMPREPLY} array
+variable.
+
+Next, any command specified with the @option{-C} option is invoked
+in an environment equivalent to command substitution.
+It should print a list of completions, one per line, to
+the standard output.
+Backslash may be used to escape a newline, if necessary.
+
+After all of the possible completions are generated, any filter
+specified with the @option{-X} option is applied to the list.
+The filter is a pattern as used for pathname expansion; a @samp{&}
+in the pattern is replaced with the text of the word being completed.
+A literal @samp{&} may be escaped with a backslash; the backslash
+is removed before attempting a match.
+Any completion that matches the pattern will be removed from the list.
+A leading @samp{!} negates the pattern; in this case any completion
+not matching the pattern will be removed.
+
+Finally, any prefix and suffix specified with the @option{-P} and @option{-S}
+options are added to each member of the completion list, and the result is
+returned to the Readline completion code as the list of possible
+completions.
+
+If the previously-applied actions do not generate any matches, and the
+@option{-o dirnames} option was supplied to @code{complete} when the
+compspec was defined, directory name completion is attempted. 
+
+If the @option{-o plusdirs} option was supplied to @code{complete} when
+the compspec was defined, directory name completion is attempted and any
+matches are added to the results of the other actions.
+
+By default, if a compspec is found, whatever it generates is returned to
+the completion code as the full set of possible completions.
+The default Bash completions are not attempted, and the Readline default
+of filename completion is disabled.
+If the @option{-o bashdefault} option was supplied to @code{complete} when
+the compspec was defined, the default Bash completions are attempted
+if the compspec generates no matches.
+If the @option{-o default} option was supplied to @code{complete} when the
+compspec was defined, Readline's default completion will be performed
+if the compspec (and, if attempted, the default Bash completions)
+generate no matches.
+
+When a compspec indicates that directory name completion is desired,
+the programmable completion functions force Readline to append a slash
+to completed names which are symbolic links to directories, subject to
+the value of the @var{mark-directories} Readline variable, regardless
+of the setting of the @var{mark-symlinked-directories} Readline variable.
+
+@node Programmable Completion Builtins
+@section Programmable Completion Builtins
+@cindex completion builtins
+
+Two builtin commands are available to manipulate the programmable completion
+facilities.
+
+@table @code
+@item compgen
+@btindex compgen
+@example
+@code{compgen [@var{option}] [@var{word}]}
+@end example
+
+Generate possible completion matches for @var{word} according to
+the @var{option}s, which may be any option accepted by the
+@code{complete}
+builtin with the exception of @option{-p} and @option{-r}, and write
+the matches to the standard output.
+When using the @option{-F} or @option{-C} options, the various shell variables
+set by the programmable completion facilities, while available, will not
+have useful values.
+
+The matches will be generated in the same way as if the programmable
+completion code had generated them directly from a completion specification
+with the same flags.
+If @var{word} is specified, only those completions matching @var{word}
+will be displayed.
+
+The return value is true unless an invalid option is supplied, or no
+matches were generated.
+
+@item complete
+@btindex complete
+@example
+@code{complete [-abcdefgjksuv] [-o @var{comp-option}] [-A @var{action}] [-G @var{globpat}] [-W @var{wordlist}]
+[-P @var{prefix}] [-S @var{suffix}] [-X @var{filterpat}] [-F @var{function}]
+[-C @var{command}] @var{name} [@var{name} @dots{}]}
+@code{complete -pr [@var{name} @dots{}]}
+@end example
+
+Specify how arguments to each @var{name} should be completed.
+If the @option{-p} option is supplied, or if no options are supplied, existing
+completion specifications are printed in a way that allows them to be
+reused as input.
+The @option{-r} option removes a completion specification for
+each @var{name}, or, if no @var{name}s are supplied, all
+completion specifications.
+
+The process of applying these completion specifications when word completion
+is attempted is described above (@pxref{Programmable Completion}).
+
+Other options, if specified, have the following meanings.
+The arguments to the @option{-G}, @option{-W}, and @option{-X} options
+(and, if necessary, the @option{-P} and @option{-S} options)
+should be quoted to protect them from expansion before the
+@code{complete} builtin is invoked.
+
+
+@table @code
+@item -o @var{comp-option}
+The @var{comp-option} controls several aspects of the compspec's behavior
+beyond the simple generation of completions.
+@var{comp-option} may be one of: 
+
+@table @code
+
+@item bashdefault
+Perform the rest of the default Bash completions if the compspec
+generates no matches.
+
+@item default
+Use Readline's default filename completion if the compspec generates
+no matches.
+
+@item dirnames
+Perform directory name completion if the compspec generates no matches.
+
+@item filenames
+Tell Readline that the compspec generates filenames, so it can perform any
+filename-specific processing (like adding a slash to directory names or
+suppressing trailing spaces).  This option is intended to be used with
+shell functions specified with @option{-F}.
+
+@item nospace
+Tell Readline not to append a space (the default) to words completed at
+the end of the line.
+
+@item plusdirs
+After any matches defined by the compspec are generated, 
+directory name completion is attempted and any
+matches are added to the results of the other actions.
+
+@end table
+
+@item -A @var{action}
+The @var{action} may be one of the following to generate a list of possible
+completions:
+
+@table @code
+@item alias
+Alias names.  May also be specified as @option{-a}.
+
+@item arrayvar
+Array variable names.
+
+@item binding
+Readline key binding names (@pxref{Bindable Readline Commands}).
+
+@item builtin
+Names of shell builtin commands.  May also be specified as @option{-b}.
+
+@item command
+Command names.  May also be specified as @option{-c}.
+
+@item directory
+Directory names.  May also be specified as @option{-d}.
+
+@item disabled
+Names of disabled shell builtins.
+
+@item enabled
+Names of enabled shell builtins.
+
+@item export
+Names of exported shell variables.  May also be specified as @option{-e}.
+
+@item file
+File names.  May also be specified as @option{-f}.
+
+@item function
+Names of shell functions.
+
+@item group
+Group names.  May also be specified as @option{-g}.
+
+@item helptopic
+Help topics as accepted by the @code{help} builtin (@pxref{Bash Builtins}).
+
+@item hostname
+Hostnames, as taken from the file specified by the
+@env{HOSTFILE} shell variable (@pxref{Bash Variables}).
+
+@item job
+Job names, if job control is active.  May also be specified as @option{-j}.
+
+@item keyword
+Shell reserved words.  May also be specified as @option{-k}.
+
+@item running
+Names of running jobs, if job control is active.
+
+@item service
+Service names.  May also be specified as @option{-s}.
+
+@item setopt
+Valid arguments for the @option{-o} option to the @code{set} builtin
+(@pxref{The Set Builtin}).
+
+@item shopt
+Shell option names as accepted by the @code{shopt} builtin
+(@pxref{Bash Builtins}).
+
+@item signal
+Signal names.
+
+@item stopped
+Names of stopped jobs, if job control is active.
+
+@item user
+User names.  May also be specified as @option{-u}.
+
+@item variable
+Names of all shell variables.  May also be specified as @option{-v}.
+@end table
+
+@item -G @var{globpat}
+The filename expansion pattern @var{globpat} is expanded to generate
+the possible completions.
+
+@item -W @var{wordlist}
+The @var{wordlist} is split using the characters in the
+@env{IFS} special variable as delimiters, and each resultant word
+is expanded.
+The possible completions are the members of the resultant list which
+match the word being completed.
+
+@item -C @var{command}
+@var{command} is executed in a subshell environment, and its output is
+used as the possible completions.
+
+@item -F @var{function}
+The shell function @var{function} is executed in the current shell
+environment.
+When it finishes, the possible completions are retrieved from the value
+of the @env{COMPREPLY} array variable.
+
+@item -X @var{filterpat}
+@var{filterpat} is a pattern as used for filename expansion.
+It is applied to the list of possible completions generated by the
+preceding options and arguments, and each completion matching
+@var{filterpat} is removed from the list.
+A leading @samp{!} in @var{filterpat} negates the pattern; in this
+case, any completion not matching @var{filterpat} is removed.
+
+@item -P @var{prefix}
+@var{prefix} is added at the beginning of each possible completion
+after all other options have been applied.
+
+@item -S @var{suffix}
+@var{suffix} is appended to each possible completion
+after all other options have been applied.
+@end table
+
+The return value is true unless an invalid option is supplied, an option
+other than @option{-p} or @option{-r} is supplied without a @var{name}
+argument, an attempt is made to remove a completion specification for
+a @var{name} for which no specification exists, or
+an error occurs adding a completion specification.

+Subject: fgets(stdin) --> readline() redirector
+To: chet@po.cwru.edu
+
+Hi Chet,
+
+Here is something you may find useful enough to include in the readline
+distribution.  It is a shared library that redirects calls to fgets(stdin)
+to readline() via LD_PRELOAD, and it supports a custom prompt and list of
+command names.  Many people have asked me for this file, so I thought I'd
+pass it your way in hope of just including it with readline to begin with.
+
+Best Regards,
+
+-Harold
+*/

+*******************************************************************************
+  
+  FILE NAME:    fgets.c                  TARGET:   libfgets.so
+  AUTHOR:       Harold Levy              VERSION:  1.0
+                hlevy@synopsys.com
+  
+  ABSTRACT:  Customize fgets() behavior via LD_PRELOAD in the following ways:
+  
+    -- If fgets(stdin) is called, redirect to GNU readline() to obtain
+       command-line editing, file-name completion, history, etc.
+  
+    -- A list of commands for command-name completion can be configured by
+       setting the environment-variable FGETS_COMMAND_FILE to a file containing
+       the list of commands to be used.
+  
+    -- Command-line editing with readline() works best when the prompt string
+       is known; you can set this with the FGETS_PROMPT environment variable.
+  
+    -- There special strings that libfgets will interpret as internal commands:
+  
+           _fgets_reset_    reset the command list
+  
+           _fgets_dump_     dump status
+  
+           _fgets_debug_    toggle debug messages
+
+  HOW TO BUILD:  Here are examples of how to build libfgets.so on various
+  platforms; you will have to add -I and -L flags to configure access to
+  the readline header and library files.
+
+  (32-bit builds with gcc)
+  AIX:   gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline -ltermcap
+  HP-UX: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldld -lreadline
+  Linux: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lreadline
+  SunOS: gcc -fPIC fgets.c -shared -o libfgets.so -lc -ldl -lgen -lreadline
+
+  (64-bit builds without gcc)
+  SunOS: SUNWspro/bin/cc -D_LARGEFILE64_SOURCE=1 -xtarget=ultra -xarch=v9 \
+           -KPIC fgets.c -Bdynamic -lc -ldl -lgen -ltermcap -lreadline
+  
+  HOW TO USE:  Different operating systems have different levels of support
+  for the LD_PRELOAD concept.  The generic method for 32-bit platforms is to
+  put libtermcap.so, libfgets.so, and libreadline.so (with absolute paths)
+  in the LD_PRELOAD environment variable, and to put their parent directories
+  in the LD_LIBRARY_PATH environment variable.  Unfortunately there is no
+  generic method for 64-bit platforms; e.g. for 64-bit SunOS, you would have
+  to build both 32-bit and 64-bit libfgets and libreadline libraries, and
+  use the LD_FLAGS_32 and LD_FLAGS_64 environment variables with preload and
+  library_path configurations (a mix of 32-bit and 64-bit calls are made under
+  64-bit SunOS).
+  
+  EXAMPLE WRAPPER:  Here is an example shell script wrapper around the
+  program "foo" that uses fgets() for command-line input:
+
+      #!/bin/csh
+      #### replace this with the libtermcap.so directory:
+      set dir1 = "/usr/lib"
+      #### replace this with the libfgets.so directory:
+      set dir2 = "/usr/fgets"
+      #### replace this with the libreadline.so directory:
+      set dir3 = "/usr/local/lib"
+      set lib1 = "${dir1}/libtermcap.so"
+      set lib2 = "${dir2}/libfgets.so"
+      set lib3 = "${dir3}/libreadline.so"
+      if ( "${?LD_PRELOAD}" ) then
+        setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}:${LD_PRELOAD}"
+      else
+        setenv LD_PRELOAD "${lib1}:${lib2}:${lib3}"
+      endif
+      if ( "${?LD_LIBRARY_PATH}" ) then
+        setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}:${LD_LIBRARY_PATH}"
+      else
+        setenv LD_LIBRARY_PATH "${dir1}:${dir2}:${dir3}"
+      endif
+      setenv FGETS_COMMAND_FILE "${dir2}/foo.commands"
+      setenv FGETS_PROMPT       "foo> "
+      exec "foo" $*

+rlfe (ReadLine Front-End) is a "universal wrapper" around readline.
+You specify an interactive program to run (typically a shell), and
+readline is used to edit input lines.
+
+There are other such front-ends; what distinguishes this one is that
+it monitors the state of the inferior pty, and if the inferior program
+switches its terminal to raw mode, then rlfe passes your characters
+through directly.  This basically means you can run your entire
+session (including bash and terminal-mode emacs) under rlfe.
+
+FEATURES
+
+* Can use all readline commands (and history) in commands that
+read input lines in "canonical mode" - even 'cat'!
+
+* Automatically switches between "readline-editing mode" and "raw mode"
+depending on the terminal mode.  If the inferior program invokes
+readline itself, it will do its own line editing.  (The inferior
+readline will not know about rlfe, and it will have its own history.)
+You can even run programs like 'emavs -nw' and 'vi' under rlfe.
+The goal is you could leave rlfe always on without even knowing
+about it.  (We're not quite there, but it works tolerably well.)
+
+* The input line (after any prompt) is changed to bold-face.
+
+INSTALL
+
+The usual: ./configure && make && make install
+
+Note so far rlfe has only been tested on GNU Linux (Fedora Core 2)
+and Mac OS X (10.3).
+
+This assumes readline header files and libraries are in the default
+places.  If not, you can create a link named readline pointing to the
+readline sources.  To link with libreadline.a and libhistory.a
+you can copy or link them, or add LDFLAGS='-/path/to/readline' to
+the make command-line.
+
+USAGE
+
+Just run it.  That by default runs bash.  You can run some other
+command by giving it as command-line arguments.
+
+There are a few tweaks:  -h allows you to name the history file,
+and -s allows you to specify its size.  It default to "emacs" mode,
+but if the the environment variable EDITOR is set to "vi" that
+mode is chosen.
+
+ISSUES
+
+* The mode switching depends on the terminal mode set by the inferior
+program.  Thus ssh/telnet/screen-type programs will typically be in
+raw mode, so rlfe won't be much use, even if remote programs run in
+canonical mode.  The work-around is to run rlfe on the remote end.
+
+* Echo supression and prompt recognition are somewhat fragile.
+(A protocol so that the o/s tty code can reliably communicate its
+state to rlfe could solve this problem, and the previous one.)
+
+* See the intro to rlfe.c for more notes.
+
+* Assumes a VT100-compatible terminal, though that could be generalized
+if anybody cares.
+
+* Requires ncurses.
+
+* It would be useful to integrate rlfe's logic in a terminal emulator.
+That would make it easier to reposition the edit position with a mouse,
+integrate cut-and-paste with the system clipboard, and more robustly
+handle escape sequence and multi-byte characters more robustly.

+ * mode, echo'd input, etc.  That would also allow a user preference
+ * to set different colors for prompt, input, stdout, and stderr.
+ *
+ * When running mc -c under the Linux console, mc does not recognize
+ * mouse clicks, which mc does when not running under rlfe.
+ *
+ * Pasting selected text containing tabs is like hitting the tab character,
+ * which invokes readline completion.  We don't want this.  I don't know
+ * if this is fixable without integrating rlfe into a terminal emulator.
+ *
+ * Echo suppression is a kludge, but can only be avoided with better kernel
+ * support: We need a tty mode to disable "real" echoing, while still
+ * letting the inferior think its tty driver to doing echoing.
+ * Stevens's book claims SCR$ and BSD4.3+ have TIOCREMOTE.
+ *
+ * The latest readline may have some hooks we can use to avoid having
+ * to back up the prompt. (See HAVE_ALREADY_PROMPTED.)
+ *
+ * Desirable readline feature:  When in cooked no-echo mode (e.g. password),
+ * echo characters are they are types with '*', but remove them when done.
+ *
+ * Asynchronous output while we're editing an input line should be
+ * inserted in the output view *before* the input line, so that the
+ * lines being edited (with the prompt) float at the end of the input.
+ *
+ * A "page mode" option to emulate more/less behavior:  At each page of
+ * output, pause for a user command.  This required parsing the output
+ * to keep track of line lengths.  It also requires remembering the
+ * output, if we want an option to scroll back, which suggests that
+ * this should be integrated with a terminal emulator like xterm.

+
+   CRIS cpu virtual device (very rudimental; generic enough for all
+   currently used CRIS versions).
+
+
+   DESCRIPTION
+
+   Implements the external CRIS functionality.  This includes the
+   delivery of interrupts generated from other devices.
+
+
+   PROPERTIES
+
+   vec-for-int = <int-a> <vec-a> <int-b> <vec-b> ...
+   These are the translations to interrupt vector for values appearing
+   on the "int" port, as pairs of the value and the corresponding
+   vector.  Defaults to no translation.  All values that may appear on
+   the "int" port must be defined, or the device aborts.
+
+   multiple-int = ("abort" | "ignore_previous" | <vector>)
+   If multiple interrupt values are dispatched, this property decides
+   what to do.  The value is either a number corresponding to the
+   vector to use, or the string "abort" to cause a hard abort, or the
+   string "ignore_previous", to silently use the new vector instead.
+   The default is "abort".
+
+
+   PORTS
+
+   int (input)
+   Interrupt port.  An event with a non-zero value on this port causes
+   an interrupt.  If, after an event but before the interrupt has been
+   properly dispatched, a non-zero value appears that is different
+   after mapping than the previous, then the property multiple_int
+   decides what to do.
+
+   FIXME: reg port so internal registers can be read.  Requires
+   chip-specific versions, though.  Ports "nmi" and "reset".
+
+
+   BUGS
+   When delivering an interrupt, this code assumes that there is only
+   one processor (number 0).
+
+   This code does not attempt to be efficient at handling pending
+   interrupts.  It simply schedules the interrupt delivery handler
+   every instruction cycle until all pending interrupts go away.
+   It also works around a bug in sim_events_process when doing so.

+
+   rv - Remote Virtual component
+
+
+   DESCRIPTION
+
+
+   Socket connection to a remote simulator component, for example one
+   for testing a verilog construction.  Protocol defined below.
+
+   There is a set of 32-bit I/O ports, with a mapping from local to
+   remote addresses.  There is a set of interrupts expressed as a
+   bit-mask, with a mapping from remote to local.  There is a set of
+   memory ranges (actual memory defined elsewhere), also with a
+   mapping from remote to local addresses, that is expected to be
+   accessible to the remote simulator in 32-byte chunks (simulating
+   DMA).  There is a mapping from remote cycles (or an appropriate
+   elsewhere defined time-slice) to local cycles.
+
+   PROPERTIES
+
+   reg = <address> <size>
+   The address (within the parent bus) that this device is to
+   be located.
+
+   remote-reg = <remote-address>
+   The address of reg on the remote side.  Defaults to 0.
+
+   mem = <address> <size>
+   Specify an address-range (within the parent bus) that the remote
+   device can access.  The memory is assumed to be already defined.
+   If there's no memory defined but the remote side asks for a memory
+   access, the simulation is aborted.
+
+   remote-mem = <remote-address>
+   The address of mem on the remote side.  Defaults to 0.
+
+   mbox = <address>
+   Address of the mailbox interface.  Writes to this address with the
+   local address of a mailbox command, a complete packet with length
+   and command; (4 or 6)) invokes the mailbox interface.  Reads are
+   invalid.  Replies are written to the same address.  Address space
+   from <address> up-to-and-including <address>+3 is allocated.
+
+   max-poll-ticks = <local-count>
+   Sets the maximum interval between polling the external component,
+   expressed in internal cycles.  Defaults to 10000.
+
+   watchdog-interval = <seconds>
+   Sets the wallclock seconds between watchdog packets sent to the
+   remote side (may be larger if there's no rv activity in that time).
+   Defaults to 30.  If set to 0, no watchdog packets are sent.
+
+   intnum = <local-int-0> <local-int-1> ... <local-int-31>
+   Defines a map from remote bit numbers to local values to be emitted
+   on the "int" port, with the external bit number as the ordinal - 1
+   of the local translation.  E.g. 43 121 would mean map external
+   (1<<0) to internal 43 and external (1<<1) to internal 121.  The
+   default is unity; no translation.  If more than one bit is set in
+   the remote interrupt word, the intmultiple property can be used to
+   control the translation.
+
+   intmultiple = <intvalue>
+   When more than one bit is set in the remote interrupt word, you may
+   want to map this situation to a separate interrupt value.  If this
+   property is non-zero, it is used as that value.  If it is zero, the
+   local value for the "int" port is the bitwise-or of the translated
+   local values.
+
+   host = <hostid>
+   The hostname or address where the simulator to be used listens.
+   Defaults to "127.0.0.1"
+
+   port = <portnumber>
+   The hostname or address where the simulator to be used listens.
+   Defaults to 10000.
+
+   dummy = <value>
+    or
+   dummy = <filename>
+   Don't connect to a remote side; use initial dummy contents from
+   <filename> (which has to be at least as big as the <size> argument
+   of reg above) or filled with byte-value <value>.  Mailboxes are not
+   supported (can be defined but can not be used) and remote-memory
+   accesses don't apply.  The main purpose for this property is to
+   simplify use of configuration and simulated hardware that is
+   e.g. only trivially initialized but not actually used.
+
+
+   PORTS
+
+   int (output)
+   Driven as a result of a remote interrupt request.  The value is a
+   32-bit bitset of active interrupts.
+
+
+   BUGS
+
+   All and none.
+
+
+   PROTOCOL
+
+   This is version 1.0 of this protocol, defining packet format and
+   actions in a supposedly upward-compatible manner where client and
+   servers of different versions are expected to interoperate; the
+   format and the definitions below are hopefully generic enough to
+   allow this.
+
+   Each connection has a server and a client (this code); the roles
+   are known beforehand.  The client usually corresponds to a CPU and
+   memory system and the server corresponds to a memory-mapped
+   register hardware interface and/or a DMA controller.  They
+   communicate using packets with specific commands, of which some
+   require replies from the other side; most are intiated by the
+   client with one exception.  A reply uses the same format as the
+   command.
+
+   Packets are at least three bytes long, where the first two bytes
+   form a header, a 16-bit little-endian number that is the total
+   length of the packet including the header.  There is also a
+   one-byte command.  The payload is optional, depending on the
+   command.
+
+   [[16-bit-low-byte-of-length] [16-bit-high-byte-of-length]
+    [command/reply] [payload byte 0] [payload byte 1]
+    ... [payload byte (length-of-packet - 3)]]
+
+   Commands:
+
+   A client or server that reads an undocumented command may exit with
+   a hard error.  Payload not defined or disallowed below is ignored.
+
+   It is expected that future client versions find out the version of
+   the server side by polling with base commands, assuming earlier
+   versions if a certain reply isn't seen, with newly defined payload
+   parts where earlier versions left it undefined.  New commands and
+   formats are sent only to the other side after the client and server
+   has found out each others version.  Not all servers support all
+   commands; the type of server and supported set of commands is
+   expected to be known beforehand.
+
+   RV_READ_CMD = 0
+   Initiated by the client, requires a reply from the server.  The
+   payload from the client is at least 4 bytes, forming a 4-byte
+   little-endian address, the rest being undefined.  The reply from
+   the server is at least 8 bytes, forming the same address data as in
+   the request and the second 4-byte data being the little-endian
+   contents.
+
+   RV_WRITE_CMD = 1
+   Initiated by the client, requires a reply from the server.  Payload
+   from the client is at least 8 bytes, forming a 4-byte little-endian
+   word being the address, the rest being the little-endian contents
+   to write.  The reply from the server is 8 bytes unless elsewhere
+   agreed otherwise, forming the same address and data as in the
+   request.  The data sent back may have been altered to correspond to
+   defined parts but can safely be discarded.
+
+   RV_IRQ_CMD = 2
+   Initiated by the server, no reply.  The payload is 4 bytes, forming
+   a little-endian word with bits numbers corresponding to currently
+   active interrupt sources; value (1<<N) indicating interrupt source
+   N being active.
+
+   RV_MEM_RD_CMD = 3
+   Initiated by the server, requires a reply.  A client must know
+   beforehand when (in command sequence or constant) the server can
+   send this command and if so must then not send any commands of its
+   own (including watchdog commands); the server is allowed to assume
+   that incoming data is only replies to this command.  The format is
+   8 bytes of data; 4 bytes of little-endian address followed by a
+   32-bit little endian word with the number of bytes to read.  The
+   reply is the same address and number of bytes, followed by the data
+   that had been read.
+
+   RV_MEM_WR_CMD = 4
+   Initiated by the server, no reply.  The format is the same as a
+   reply to RV_MEM_RD_CMD; a 32-bit little-endian address, followed by
+   the 32-bit little-endian number of bytes to write (redundant
+   information but must be consistent with the packet header).
+
+   RV_MBOX_HANDLE_CMD = 5
+   Initiated by the client, requires a reply.  The payload is 4
+   undefined bytes followed by an binary blob, the size of the
+   blob given by the packet header.  The reply is a 32-bit little
+   endian number at the same index as the undefined bytes.  Actual
+   semantics are application-specific.
+
+   RV_MBOX_PUT_CMD = 6
+   Initiated by the client, requires a reply, with the reply using the
+   RV_MBOX_HANDLE_CMD reply format (i.e. *both* that command and
+   32-bit little-endian number).  The payload is a 32-bit little
+   endian number followed by an undefined payload, at most 20 bytes
+   long.  The reply is a 32-bit little endian number.  Actual
+   semantics are application-specific.
+
+   RV_WATCHDOG_CMD = 7
+   Initiated by the client, no reply.  A version 1.0 client sends no
+   payload; a version 1.0 server should ignore any such payload.  A
+   version 1.0 server must not send a reply.
+
+
+   Possible future enhancements:
+
+   Synchronization; server and client reports the number of elapsed
+   cycles (unit to-be-defined) at each request or notification.
+   Pretty much the top-of-the-todo-list item.
+
+   Large addresses; 1.0 being restricted to 32-bit addresses.
+
+   Variable-size data; currently restricted to 32-bit register
+   accesses.
+
+   Specified data endianness (not the packet header) perhaps as part
+   of an initial format request; currently little-endian only.
+
+
+   Usage notes:
+   When used with servers sending RV_MEM_RD_CMD but being
+   narrow-minded about indata, set watchdog-interval to 0.  Use
+   multiple rv instances when there are e.g. separate register and
+   memory servers.  Alway log, setting "/rv/trace? true", at the
+   development phase.  Borrow from the test-suite.
