The prestigious university Cambridge's Department
of Applied Mathematics
and Theoretical Physics (D.A.M.T.P) maintains
of Emacs Lisp files submitted from people all around the
world for the purposes of extending the Emacs text editor.
If you publish an Emacs Lisp file to this list on your
website, the link from Cambridge University to your website
will optimise your website for indexing by search engines.
I have several Emacs Lisp files lying around waiting to be
published. By hosting one of the Lisp files on your website
you will optimise your site for indexing by search engines.
