    (description
     "GDB is the GNU debugger.  With it, you can monitor what a program is
doing while it runs or what it was doing just before a crash.  It allows you
to specify the runtime conditions, to define breakpoints, and to change how
the program is running to try to fix bugs.  It can be used to debug programs
written in C, C++, Ada, Objective-C, Pascal and more.")
