32.6 Running Debuggers Under Emacs
The GUD (Grand Unified Debugger) library provides an interface to
various symbolic debuggers from within Emacs. We recommend the
debugger GDB, which is free software, but you can also run DBX, SDB or
XDB if you have them. GUD can also serve as an interface to Perl's
debugging mode, the Python debugger PDB, the bash debugger, and to
JDB, the Java Debugger. See The Lisp Debugger, for information on debugging Emacs
Lisp programs.
