+DDD is the Data Display Debugger, a common graphical front-end for
+GDB, DBX, and XDB debuggers.
+
+DDD is an Motif application that besides the "usual" features such as viewing
+source texts and breakpoints, DDD provides a _graphical_data_display_, where
+data structures are displayed as graphs. A simple mouse click dereferences
+pointers or reveals structure contents. Complex data structures can be
+explored incrementally and interactively, using automatic layout if
+preferred. Each time the program stops, the data display reflects the
+current variable values.
