egg

 

Easy Install is deprecated. Do not use it. Instead use pip.

PEAK(Python Enterprise Application Kit)

"easy_install" bundled with "setuptools"

Usage:

easy_install somepackage.egg

easy_install http://somehost.somedomain.com/somepackage.egg

dist-packages

In Debian : "Third party Python software installed from Debian packages goes into dist-packages, not site-packages. This is to reduce conflict between the system Python, and any from-source Python build you might install manually. "
