Binary File Descriptor Library Support for GDB
**********************************************

   BFD provides support for GDB in several ways:

*identifying executable and core files*
     BFD will identify a variety of file types, including a.out, coff,
     and several variants thereof, as well as several kinds of core
     files.

*access to sections of files*
     BFD parses the file headers to determine the names, virtual
     addresses, sizes, and file locations of all the various named
     sections in files (such as the text section or the data section).
     GDB simply calls BFD to read or write section X at byte offset Y
     for length Z.

*specialized core file support*
     BFD provides routines to determine the failing command name stored
     in a core file, the signal with which the program failed, and
     whether a core file matches (i.e. could be a core dump of) a
     particular executable file.

*locating the symbol information*
     GDB uses an internal interface of BFD to determine where to find
     the symbol information in an executable file or symbol-file.  GDB
     itself handles the reading of symbols, since BFD does not
     "understand" debug symbols, but GDB uses BFD's cached information
     to find the symbols, string table, etc.
