It will be autogenerated, with input from auctex.el.in which is
currently tex-site.el.in, but quite different.  In short, I am talking
about a structure that will take at least a week until it is visible
in the CVS.  It is still cooking right now.

Autoloads, load-path and other directory setup.  Pretty much
everything to get it to run.

It also defines a few other variables, and the clean unloading is what
I have been asking about here.  Making it unload painlessly is
important so that providers of precompiled packages have no qualms
autostarting it.  If you can answer to a complaint just
"(unload-feature 'auctex)", then administrators will not get worried
about the 5% of their users that have a strong preference, and for
tex-mode.el.

I'll worry about that once AUCTeX becomes part of Emacs proper and we
will not have to cater for backward compatibility, anyway.  And there
are a few years before we are there.

In the mean time, Emacs provides enough ways for unsuspecting users to
shoot themselves in the foot, and the alias configuration of a
pristine Emacs is probably the least of our worries.
