[TriZPUG] Reference The Current Version Of Your Python Egg In Your Modules

[Joseph S. Tate]

I do something similar, I don't know of a way to read the package version
from setuptools, though it's likely there somewhere.

I usually have a 'version.py' file that contains "VERSION="1.0.3r9" (or
whatever).

Then in my setup.py I run "execfile(os.path.join('PKGNAME',
'version.py'))". Then VERSION is available locally. Where I need to use it
in code, I'll from pkg.version import VERSION.
