Severity: wishlist

The *-pkg.el files are not source files that should be executed, but
Lisp data files.  This has been the source of much confusion.

For example, it is currently completely confused in the lispref manual,
which talks about `define-package' as a function, despite the fact that
it has never been working like that and is now obsolete.  (I'm working
on a patch.)

I think we should install the following to start clearing up some of the
confusion.

Thoughts?
