Adding a new style file to auctex

[alephnull@airtelbroadband.in (Alok G. Singh)]

I have been trying to install the qcm class [1] to typeset question
papers. 

I have added qcm.el to /usr/share/emacs/site-lisp/auctex/Makefile.in and
ran update-auctex-elisp and qcm.elc was written to
/var/lib/auctex. However, I am unable to use the features of qcm.el. Is
there any additional setup required to add a new style to auctex ?
