I am told we are using a derivative or variant of perforce called source depot. I don't know how this could be because I've used perforce before and this command line interface is quite different. Also, I don't understand how a derivative or variant of a commercial product like perforce could exist.

I do have rcs installed for my personal use: that must be able to compute and execute deltas.

Anyway, I did not select source depot. I'm just "contingency staff". It's command line interface sure is crude compared to the nice GUIs available for CVS and SVN.

My prediction came true again today! Only this time, it is because I broke the build and I have to revert everything to fix that immediately.

So I did my editing with using elisp code and saved that code so I could execute my editing changes again. There must be a better way!
