mod_wsgi WSGIPythonHome directive

Description

Used to indicate to Python when it is initialised where its library files are installed. This should be defined where the Python executable is not in the PATH of the user that Apache runs as, or where a system has multiple versions of Python installed in different locations in the file system, especially different installations of the same major/minor version, and the installation that Apache finds in its PATH is not the desired one.

This directive can also be used to indicate a Python virtual environment created using a tool such as virtualenv, to be used for the whole of mod_wsgi.
