Looking this up based on __file__ would be more robust than cwd.

Calling this doctree is misleading because doctree is a specific Sphinx
term that means something else. The doctree directory is where the
parsed and pickled documents are cached.

Oh, I see that you're just moving this, but this is something that
should be fixed first.

These would be much nicer with pathlib.Path.
