+Dean Elsner wrote the original gas for vax.  [more details?]
+
+Jay Fenlason maintained gas for a while, adding support for
+gdb-specific debug information and the 68k series machines, most of
+the preprocessing pass, and extensive changes in messages.c,
+input-file.c, write.c.
+
+K. Richard Pixley maintained gas for a while, adding various
+enhancements and bug fixes.  [what in particular did Rich do? get
+details from rich and/or changelog]
+
+Ken Raeburn currently maintains gas, and wrote the high-level BFD
+interface code to replace most of the code in format-specific I/O
+modules.

+Youngdale has done much work with it since.

+
+Support for the Zilog Z8k and Hitachi H8/300 and H8/500 processors
+(tc-z8k, tc-h8300, tc-h8500), and IEEE 695 object file format
+(obj-ieee), was written by Steve Chamberlain of Cygnus Support.  Steve
+also modified the COFF back end to use BFD for some low-level
+operations, for use with the H8/300 and AMD 29k targets.
+
+John Gilmore worked on the AMD 29000 support.  [doing what?  any major
+work on other parts?]
+
+Ian Lance Taylor of Cygnus Support merged the Motorola and MIT
+syntaxes for the 68k, completed support for some COFF targets (68k,
+i386 SVR3, and SCO Unix), and made a few other minor patches.
+
+Support for generation of listings was added by Steve Chamberlain.
+
+Several engineers at Cygnus Support have also provided many small bug
+fixes and configuration enhancements.
+
+
+Many others have contributed large or small bugfixes and enhancements,
