-BFD trys to maintain as much symbol information as it can when it
-moves information from file to file. BFD passes information to
-applications though the @code{asymbol} structure. When the application
-requests the symbol table, BFD reads the table in the native form and
-translates parts of it into the internal format. To maintain more than
-the infomation passed to applications some targets keep
-some information 'behind the sceans', in a structure only the
-particular back end knows about. For example, the coff back end keeps
-the original symbol table structure as well as the canonical structure
-when a BFD is read in. On output, the coff back end can reconstruct
-the output symbol table so that no information is lost, even
-information unique to coff which BFD doesn't know or understand. If a
-coff symbol table was read, but was written through an a.out back end,
-all the coff specific information would be lost. (.. until BFD 2 :).
-
-The symbol table of a BFD is not necessarily read in until a
-canonicalize request is made. Then the BFD back end fills in a table
-provided by the application with pointers to the canonical
-information.
-
-To output symbols, the application provides BFD with a table of
-pointers to pointers to @code{asymbol}s. This allows applications like
-the linker to output a symbol as read, since the 'behind the sceens'

+ BFD tries to maintain as much symbol information as it can when
+ it moves information from file to file. BFD passes information
+ to applications though the <<asymbol>> structure. When the
+ application requests the symbol table, BFD reads the table in
+ the native form and translates parts of it into the internal
+ format. To maintain more than the information passed to
+ applications, some targets keep some information ``behind the
+ scenes'' in a structure only the particular back end knows
+ about. For example, the coff back end keeps the original
+ symbol table structure as well as the canonical structure when
+ a BFD is read in. On output, the coff back end can reconstruct
+ the output symbol table so that no information is lost, even
+ information unique to coff which BFD doesn't know or
+ understand. If a coff symbol table were read, but were written
+ through an a.out back end, all the coff specific information
+ would be lost. The symbol table of a BFD
+ is not necessarily read in until a canonicalize request is
+ made. Then the BFD back end fills in a table provided by the
+ application with pointers to the canonical information. To
+ output symbols, the application provides BFD with a table of
+ pointers to pointers to <<asymbol>>s. This allows applications
+ like the linker to output a symbol as it was read, since the ``behind
+ the scenes'' information will be still available.

-There are two stages to reading a symbol table from a BFD; allocating
-storage, and the actual reading process. This is an excerpt from an
-appliction which reads the symbol table:
-
-*+
- unsigned int storage_needed;
- asymbol **symbol_table;
- unsigned int number_of_symbols;
- unsigned int i;
-
- storage_needed = get_symtab_upper_bound (abfd);

- symbol_table = (asymbol **) malloc (storage_needed);

- number_of_symbols =
- bfd_canonicalize_symtab (abfd, symbol_table);
-
- for (i = 0; i < number_of_symbols; i++) {
- process_symbol (symbol_table[i]);
- }
-*-
-
-All storage for the symbols themselves is in an obstack connected to
-the BFD, and is freed when the BFD is closed.
-
-@node Writing Symbols, typedef asymbol, Reading Symbols, Symbols
-@subsection Writing Symbols
-Writing of a symbol table is automatic when a BFD open for writing
-is closed. The application attatches a vector of pointers to pointers to symbols
-to the BFD being written, and fills in the symbol count. The close and
-cleanup code reads through the table provided and performs all the
-necessary operations. The outputing code must always be provided with
-an 'owned' symbol; one which has come from another BFD, or one which
-has been created using @code{bfd_make_empty_symbol}.
-
-An example showing the creation of a symbol table with only one
-element:

-#include "bfd.h"
-main()
-{
- bfd *abfd;
- asymbol *ptrs[2];
