The DistUtils are a collection of several different commands to build and install python modules and extensions. DistUtils is a standard module in newer Python releases. On some Linux distribution it's in a ''python-dev'' package or similar.

Py2Exe is an additional command to DistUtils, that creates standalone distributions for Win32.
