Installation seems to work on CVS Emacs and Emacs 21.4.  I don't know
however, if I am supposed to (require 'tex-site) or (load "auctex")
right now.  Both work.

Installation for XEmacs succeeds but after starting XEmacs, the new
installation is shadowed by the old one.  Here is the start of the
output of `list-load-path-shadows':

/usr/share/xemacs21/xemacs-packages/lisp/auctex/tex-bar hides 
/usr/share/xemacs21/xemacs-packages/lisp/auctex/toolbar-x hides 
/usr/share/xemacs21/xemacs-packages/lisp/auctex/tex-fold hides 
/usr/share/xemacs21/xemacs-packages/lisp/auctex/context-nl hides 

auctex.el cannot be located with `locate-library'.

A precondition for this is to actually know how the installation is
supposed to work, what changed regarding switches, how the packages
are activated etc. etc.  Personally I am currently completely clueless
about this.

Hm, if I use `emacs -Q -l auctex-setup.el' where the loaded file
contains this:

(setq debug-on-error t)
;; (require 'tex-site)
(load "auctex")
(setq TeX-auto-save t)
(setq TeX-parse-self t)
(setq-default TeX-master nil)

doing `M-: (unload-feature 'tex-site) RET' will result in a large list
printed to the *Messages* buffer.  If I then load a LaTeX file, I
still get AUCTeX.  The same is true with my normal setup which uses
(require 'tex-site).  As I have `eval-expression-print-length' and
`eval-expression-print-level' both set to nil, printing the list to
the *Messages* buffer takes _very_ long.

In case I use the minimal setup shown above, but with (require
'tex-site) instead of (load "auctex") activated, doing `M-:
(unload-feature 'tex-site) RET' results in this backtrace:

Debugger entered--Lisp error: (error "Loaded libraries 
(\"/home/angeli/auctex-setup.el\") depend on tex-site")
  signal(error ("Loaded libraries (\"/home/angeli/auctex-setup.el\") depend on 
  error("Loaded libraries %s depend on %s" "(\"/home/angeli/auctex-setup.el\")" 
  eval((unload-feature (quote tex-site)))
  eval-expression((unload-feature (quote tex-site)) nil)

All of this unload-feature stuff was tested only with CVS Emacs.
