What am I supposed to do with an egg?!

[Morpheus]

On Windows I'm used to install packages by setup.py install. So did I with
Fibranet nanothreads - a few seconds and it was installed.

On Linux (ubuntu 6.06) all I could get at is an egg file. I found out that
I have to exec easy_install, which didn't much help here (seems to me, at
least - sorry, Linux newbie).

So, what am I supposed to do here now?

Kind regards
