[Twisted-Python] workflow

I would greatly benefit from some direction regarding workflow. In particular, how do you guys deal with having an installed version of twisted, and a version (versions?) with which to tinker? Currently, I have twisted installed in the normal end user way, and I have a clone of my fork of the git repo. I mess around in the git repo clone, but I don't know how to e.g. run the tests or run applications using the git clone. glyph explained this to me on irc a while back. Are the instructions from that recorded somehwere? Why am I asking? Because I want to do reviews and I'm not doing it because I don't know how to set up a sane environment. -- Daniel Sank
