-SYNOPSIS
-
-	void nlm_symtab_read (bfd *abfd, CORE_ADDR addr,

-DESCRIPTION
-
-	Given an open bfd, a base address to relocate symbols to, and a
-	flag that specifies whether or not this bfd is for an executable
-	or not (may be shared library for example), add all the global
-	function and data symbols to the minimal symbol table.

-/* Scan and build partial symbols for a symbol file.
-   We have been initialized by a call to nlm_symfile_init, which 
-   currently does nothing.
-
-   SECTION_OFFSETS is a set of offsets to apply to relocate the symbols
-   in each section.  We simplify it down to a single offset for all
-   symbols.  FIXME.
-
-   MAINLINE is true if we are reading the main symbol
-   table (as opposed to a shared lib or dynamically loaded file).
-
-   This function only does the minimum work necessary for letting the
-   user "name" things symbolically; it does not read the entire symtab.
-   Instead, it reads the external and static symbols and puts them in partial
-   symbol tables.  When more extensive information is requested of a
-   file, the corresponding partial symbol table is mutated into a full
-   fledged symbol table by going back and reading the symbols
-   for real.
-
-   Note that NLM files have two sets of information that is potentially
-   useful for building gdb's minimal symbol table.  The first is a list
-   of the publically exported symbols, and is currently used to build
-   bfd's canonical symbol table.  The second is an optional native debugging
-   format which contains additional symbols (and possibly duplicates of
-   the publically exported symbols).  The optional native debugging format
-   is not currently used. */
