CGDB is a curses-based interface to the GNU Debugger (GDB). The goal of CGDB
is to be lightweight and responsive; not encumbered with unnecessary features.
The interface is designed to deliver the familiar GDB text interface, with a
split screen showing the source as it executes. The UI is modeled on the
classic Unix text editor, vi. Those familiar with vi should feel right at home
using CGDB.
