You forgot this!  Anyways, I was confused by the docstring, so I took the
liberty to simplify it a little bit to the following:

  "Return a package definition named PACKAGE-NAME that packages the Emacs Lisp
SOURCE-FILES found in SOURCE-PACKAGE."

If you think this is missing something, let me know and I'll fix it.

Thanks for your great contribution!
