basically, they are called on command line level, and output some gcode on the standard output stream, if I understand correctly. There is also a second idea of having a filter menu, that gives calls individual programs with one parameter, i.e. the file name of the currently opened gcode, and expects some new gcode on the standard ouptut stream. But thats not in any default trunk.
