[mod_python] setting pythonpath for each virtual directory.

What I want is to let every site in my apache server to have a own place 
to place the site specific modules.  how do I tell apache/mod_python to 
add this to the searchpath for each site. note that one site should only 
have access to it's own module directory.

sorry for the bad enlish. tierd and swedish ;)
