From a cursory examination (and subsequent decision not to
use it) of RoboSource, done in '04, I doubt that it's any more
tightly integrated with RH than any other source control product.
That is, the adding and deleting of files is not automated to
reflect what you do inside the RH project: you must perform the
adds and deletes manually.
This was the way we worked at a previous job, where we used
Visual SourceSafe (VSS), which I believe to be the source control
product that plays best with RH (but which is not supported by IT
at this job).
Good luck,
Leon
