Extending AUCTEX

[Svend]

I have made some extensions to AUCTEX (primarily some new menus). The
extensions are activated by adding this line at the end of the file
latex.el:

  (load "auctexext")

It works but is there a better and more correct way to do it?

One problem with my way to do it is that if I install a new version I
have to add the line again.
