@unnumbered Summary of _GDBN__
The purpose of a debugger such as _GDBN__ is to allow you to see what is
is being implemented, and Fortran support will be added when a GNU
Fortran compiler is ready.

+Richard Stallman was the original author of GDB, as with many GNU
+programs. Many others have contributed to its development. This
+section attempts to credit major contributors. One of the virtues of
+free software is that everyone is free to contribute to it; with
+regret, we cannot actually acknowledge everyone here. The file
+@file{ChangeLog} in the GDB distribution approximates a blow-by-blow
+account.
+
+Changes much prior to version 2.0 are lost in the mists of time.
+
+@quotation
+@emph{Plea:} Additions to this section are particularly welcome. If you
+or your friends (or enemies; let's be evenhanded) have been unfairly
+omitted from this list, we would like to add your names!

+So that they may not regard their long labor as thankless, we
+particularly thank those who shepherded GDB through major releases:
+John Gilmore (release 4.0); Jim Kingdon (releases 3.9, 3.5, 3.4, 3.3);
+and Randy Smith (releases 3.2, 3.1, 3.0). As major maintainer of GDB
+for some period, each contributed significantly to the structure,
+stability, and capabilities of the entire debugger.
+
+Richard Stallman, assisted at various times by Pete TerMaat, Chris
+Hanson, and Richard Mlynarik, handled releases through 2.8.
+
+Michael Tiemann is the author of most of the GNU C++ support in GDB,
+with significant additional contributions from Per Bothner. James
+Clark wrote the GNU C++ demangler. Early work on C++ was by Peter
+TerMaat (who also did much general update work leading to release 3.0).
+
+GDB 4.0 uses the BFD subroutine library to examine multiple
+object-file formats; BFD was a joint project of V. Gumby
+Henkel-Wallace, Rich Pixley, Steve Chamberlain, and John Gilmore.
+
+David Johnson wrote the original COFF support; Pace Willison did
+the original support for encapsulated COFF.
+
+Adam de Boor and Bradley Davis contributed the ISI Optimum V support.
+Per Bothner, Noboyuki Hikichi, and Alessandro Forin contributed MIPS
+support. Jean-Daniel Fekete contributed Sun 386i support. Chris
+Hanson improved the HP9000 support. Noboyuki Hikichi and Tomoyuki
+Hasei contributed Sony/News OS 3 support. David Johnson contributed
+Encore Umax support. Jyrki Kuoppala contributed Altos 3068 support.
+Keith Packard contributed NS32K support. Doug Rabson contributed
+Acorn Risc Machine support. Chris Smith contributed Convex support
+(and Fortran debugging). Jonathan Stone contributed Pyramid support.
+Michael Tiemann contributed SPARC support. Tim Tucker contributed
+support for the Gould NP1 and Gould Powernode. Pace Willison
+contributed Intel 386 support. Jay Vosburgh contributed Symmetry
+support.
+
+Rich Schaefer helped with support of SunOS shared libraries.
+
+Jay Fenlason and Roland McGrath ensured that GDB and GAS agree about
+several machine instruction sets.
+
+Patrick Duval, Ted Goldstein, Vikram Koka and Glenn Engel helped
+develop remote debugging. Intel Corporation and Wind River Systems
+contributed remote debugging modules for their products.
+
+Brian Fox is the author of the readline libraries providing
+command-line editing and command history.

@unnumbered New Features in _GDBN__ version 4.0
@table @emph
can suppress output of machine-level addresses, displaying only source
language information.
+@item Command Rationalization
+Many _GDBN__ commands have been renamed to make them easier to remember
+and use. In particular, the subcommands of @code{info} and
+@code{show}/@code{set} are grouped to make the former refer to the state
+of your program, and the latter refer to the state of _GDBN__ itself.
+@xref{Renamed Commands}, for details on what commands were renamed.
+
@item Ports
_GDBN__ has been ported to the following new architectures: AT&T 3b1,
Acorn RISC machine, HP300 running HPUX, big- and little-endian MIPS
