generic virtualenv management and test command line tool.

used by coverage.py, looks pretty interesting for testing against multiple versions and environments.

works for git and hg repositories.

inspect-shell

https://github.com/amoffat/Inspect-Shell

looks like a pretty cool way to open a manhole into a running python script. it is not a debugger and it doesn't lock or interrupt. allows you to call functions, inspect or (dangerously) modify globals, etc.
