Summary     : A GNU source-level debugger for C, C++ and Fortran.
Description :
Gdb is a full featured, command driven debugger. Gdb allows you to
trace the execution of programs and examine their internal state at
any time.  Gdb works for C and C++ compiled with the GNU C compiler
gcc.

If you are going to develop C and/or C++ programs and use the GNU gcc
compiler, you may want to install gdb to help you debug your
programs.
