egg-info/PKG-INFO don't list the specific files, though.

As I mentioned previously, if the spec says anything about specific 
paths, it will be full of fail.  The spec MUST be able to work with 
*any* local policy about where Python packages are to be 
installed.  Otherwise, any tool that wants to work with install-dbs 
will end up accumulating a long list of paths to be handled specially 
for each OS vendor and version...  and still not handle everything.  No can do.

This has to be a mechanism, not a policy.  Vendors and admins should 
be able to enforce reasonable policies, without requiring that every 
tool have those policies built in.  For one thing, it's an entry 
barrier to tools.

Basically, what I'm proposing here is like WSGI for package 
management tools -- and building anything about paths into the spec 
would be like WSGI spelling out what pages should be at what URLs!
