There are some very good examples in Steve's excellent buildout.cfg for 
the UnifiedInstaller found here: 

His version precompiles the python source files, and only gives write 
permission to the effective-user on the files that need it. You can just 
plug in the values you want where you see something like __EFFECTIVE_USER__.

Have fun!
