It doesn't do anything else very substantial.  It creates a function to 
deactivate the workingenv (on Unix) and so it spends some time saving 
what PYTHONPATH was previously, it updates PATH, tweaks PS1, etc. 
That's all just for convenience (though arguably updating PATH is more 
important), but really only the PYTHONPATH update matters.
