[Distutils] py2exe and eggs

[Jay Parlar]

I followed the steps, but I believe I'm missing something basic about
eggs in general.

The py2exe result now has the two egg files in it, but the only way
I'm actually able to import them is by doing:

sys.path.append('.')
pkg_resources.require("RuleDispatch")
pkg_resources.require("PyProtocols")


at the top of my main .py file. That doesn't seem like the right thing to do...

pkg_resources.find_distributions(".") can find the distibutions fine,
but how do I tell the runtime that it should look on "." for eggs,
without having to append to sys.path?

Thanks,
Jay P.
