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. WWW: http://cgdb.sourceforge.net/
