[Python.NET] debugging

[Jason Sachs]

I'm still missing this. Here's what I tried (never mind Eclipse+pydev for
the moment, I'm just trying to run a python.exe to get what I want)

- I created a "pythonnet" directory under site-packages
- I created a "pythonnet.pth" file that contains "pythonnet"
- I added the 5 files from pythonnet into the "pythonnet" directory under
site-packages

and if I run python here's what I get: it shows up in sys.path but I can't
import System and if I import clr it gives me an error.
