description            GDB: The GNU Project Debugger

long_description \
GDB, the GNU Project debugger, allows you to see what is going on \
'inside' another program while it executes -- or what another program \
was doing at the moment it crashed.  GDB can do four main kinds of \
things (plus other things in support of these) to help you catch bugs \
in the act: \
    a) start your program, specifying anything that might affect \
       its behavior, \
    b) make your program stop on specified conditions, \
    c) examine what has happened, when your program has stopped, \
    d) change things in your program, so you can experiment with \
       correcting the effects of one bug and go on to learn about \
       another. \
The program being debugged can be written in Ada, C, C++, Objective-C, \
Pascal (and many other languages). Those programs might be executing on \
the same machine as GDB (native) or on another machine (remote). GDB \
can run on most popular UNIX and Microsoft Windows variants.
