There are too many files; the directory is very cluttered.

I read the docs for sys and site and have insufficient experience with them
to know how best to apply them for my needs.

My research suggests that rather than appending a project directory tree to
sys.path (which would make it visible to all python invocations) I'd be
better off using site within each project's root directory so modules in
project-specific subdirectories are available to that project. I would like
advice on how to do this.

Or, can I extend sys.path within each project's root directory so the
extension applies only there?
