Such a great resource, thanks guys!!

We've decided to do the workshops during the first two weeks of our
CUNY/AMNH REU program and so far, I anticipate one problem: Scisoft. There's
a bit in the Installation workshop about handling packages with multiple
python installations (
but I would like some specific advice on how to handle existing Scisoft

Specifically, if we want to keep Scisoft installed for the IRAF installation
(which we need for pyraf, right?), but NOT for the Python install, what
should we do? I figure there's some combo of environment variables that need
setting/unsetting in the .tcshrc and if someone can point us in the right
direction, that would help get us started as smoothly as possible.

Are there any other conflicts that I should anticipate with installing the
EPD on computers that have existing Python installations?

Thanks for your advice!
