There was a good module, path.py, written by Jason Orendorff. If I recall correctly, there was some discussion about adding it to the standard library then it faded away.
It looks now that there are multiple outgrowths of the original one. I can find so far unipath, what looks like a forked path.py, another one, and a few others according to PyPI.
Anyone has experience with any of those options? Is one better than the other in terms of functionality, maintenance or any other criteria? Or should I just pick one at random?
(Apologies for the whimsical title. I first went for "Which path.py?" but it was too short for SO's taste.)
