 Unpacking and Installation -- quick overview
 ==========================
 
 In this release, the binary utilities, the linker, the generic GNU include
 files, the BFD ("binary file description") library, gprof, and getopt all

+have directories of their own underneath the binutils-2.7 directory.
 The idea is that a variety of GNU tools can
 share a common copy of these things.  Configuration scripts and
 makefiles exist to cruise up and down this directory tree and
 automatically build all the pieces in the right order.
 
-When you unpack the binutils-2.1.tar.Z file, you'll get a directory called

 To build binutils, you can just do:
 
-	cd binutils-2.1
-	./configure [ --with-minimal-bfd=yes ]
+	cd binutils-2.7
+	./configure [ --enable-targets='target1,target2...' ]
 	make
-	make install # copies the programs files into /usr/local/bin by default.
-
-The --with-minimal-bfd-yes flag is a temporary kludge.  Using it makes
-the executables smaller, at the price of only being able to handle
-the default binary file format.  A more flexible mechanism is planned.
+	make install # copies the programs files into /usr/local/bin
+		     # by default.
 
 This will configure and build all the libraries as well as binutils
 and the linker.
 
+The --enable-targets option adds support for more binary file
+formats besides the default.  By default, support for only the
+selected target file format is compiled in.  To add support for more
+formats, list them as the argument to --enable-targets, separated by
+commas.  For example:
+
+	./configure --enable-targets=sun3,rs6000-aix,decstation
+
+The name 'all' compiles in support for all valid BFD targets (this was
+the default in previous releases):
+
+	./configure --enable-targets=all
+
 The binutils can be used in a cross-development environment.
-The file DOC.configure contains more information.
+The file etc/configure.texi contains more information.
+
+You can also specify the --enable-shared option when you run
+configure.  This will build the BFD and opcodes libraries as shared
+libraries.  This will only work on certain systems, and currently will
+only work when compiling with gcc.  You can use arguments with the
+--enable-shared option to indicate that only certain libraries should
+be built shared; for example, --enable-shared=bfd.  The only
+possibilities in a binutils release are bfd and opcodes.
+
+The binutils will be linked against the shared libraries.  The build
+step will attempt to place the correct library in the runtime search
+path for the binaries.  However, in some cases, after you install the
+binaries, you may have to set an environment variable, normally
+LD_LIBRARY_PATH, so that the system can find the installed libbfd
+shared library.
+
+If you specify --enable-commonbfdlib as well as --enable-shared, then
+a single shared library will be built containing the bfd, opcodes, and
+libiberty libraries.  It will be installed as libbfd.  This option
+will make the binutils programs as small as possible.
+
+If you don't have ar
+====================
+
+If your system does not already have an ar program, the normal
+binutils build process will not work.  In this case, run configure as
+usual.  Before running make, run this script:
+
+#!/bin/sh
+MAKE=${MAKE-make}
+${MAKE} $* AR=true all-libiberty
+${MAKE} $* AR=true all-bfd
+cd binutils
+${MAKE} $* ADDL_DEPS='$(BULIBS)' ADDL_LIBS='$(BULIBS) ../bfd/*.o `cat ../libiberty/required-list ../libiberty/needed-list | sed -e "s,\([^ ][^ ]*\),../libiberty/\1,g"`' ar
+
+This script will build an ar program in binutils/ar.  Move binutils/ar
+into a directory on your PATH.  After doing this, you can run make as
+usual to build the complete binutils distribution.  You do not need
+the ranlib program in order to build the distribution.
