Python path
The order and location of folders in which the Python interpreter will look for modules. It's available in python via sys.path. When Zope is running, this typically includes the global Python modules making up the standard library, the interpreter's site-packages directory, where third party "global" modules and eggs are installed, the Zope software home, and the lib/python directory inside the instance home. It is possible for python scripts to include additional paths in the Python path during runtime. This ability is used by zc.buildout.
