Hi Josh,
I dunno if this is quite what you are looking for, but my app packages always contain a file called VERSION which contains (surprisingly) the version string and nothing else. That's the only place the version resides; all other code reads it from there. For instance, I have this in my setup.py --

VERSION = open("VERSION").read().strip()


That value also gets compiled into my C code via a .h file (which is written by setup.py), it's used by the code that builds my tarballs, etc.

This also has the advantage of putting the version in a discrete, clearly marked file so that someone can see the package version even if its directory name (which typically contains the version info) gets changed.

Hope this helps,
Philip
