Support for debugging is configured by the menus.xml file. At this moment there is support for gdb.

Debugging is available if option -d is added when starting up. Markers for breakpoints and current line of execution are shown in the source code.

e.g. the next gdb commands are supported:

svn command action
breakinvokes svn add
file shows svn diff
next asks for revision and shows revision in editor window
run asks for revision and shows revision with blame info in editor window
untilasks for commit text and commits

The debug submenu is shown when right clicking on an editor window.
