Significantly simplify some code, and removes a lot of hacks.

This is a very rudimentary version. All it does is copy and rename the

subdirectory that is added as an #include-path.

There is some code duplication and cleanup necessary. There are a
few "magic strings" and "magic paths" that need to be removed as well.
