Grand Unified Debugger mode for running GDB and other debuggers
The ancestral gdb.el was by W. Schelter. It was later rewritten by rms. Some ideas were due to Masanobu. Grand Unification (sdb/dbx support) by Eric S. Raymond Barry Warsaw hacked the mode to use comint.el. Shane Hartman added support for xdb (HPUX debugger). Rick Sladkey wrote the GDB command completion code. Dave Love added the IRIX kluge, re-implemented the Mips-ish variant and added a menu. Brian D. Carlstrom combined the IRIX kluge with the gud-xdb-directories hack producing gud-dbx-directories. Derek L. Davies added support for jdb (Java debugger.) Jan Nieuwenhuizen added support for the Guile REPL (Guile debugger).
