psychic emacs

[Amadeus W. M.]

Do this on FC5:

emacs foobar.spec

Can I configure emacs to do the same with other
file types, or is it compiled in? E.g. whenever I open a blank 
foobar.cc automatically #include certain header files, and create
a usage() and main() stub. 

On second thought, maybe it's getting too close 
to M$, trying to be smarter than it should. A feature like this
should not be enabled by default, but a configuration option
would be good.
