Description

Support an attribute to add a path prefix to the import path. This will be opposite of the existing attribute - strip_path_prefixes. This is especially useful for packaging native extensions (.so) into a top-level namespace.

Would love to see this re-opened - adding a prefix would be really useful.

Posterity. This looks pretty easy. Add an attribute to py_wheel rule. Pass it as an arg to wheelmaker action. In wheelmaker.py, when writing the package file into the wheel zip, prepend the path prefix. This is right around where the strip prefix code is.
