+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!
+@end quotation
+
+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.
