defining functions in emacs

[Matt Brown <mbrown83@ucsc.edu>]

Hi everyone

I wrote my first emacs function! Here's my function:


(defun read-environment ()
  (setq outbuf (generate-new-buffer "read-environment-outbuf"))
  (call-process "read-environment.sh" nil outbuf nil)
  (eval-buffer outbuf)
  (kill-buffer outbuf))

It uses read-environment.sh to generate a whole bunch of setenv lines, 
and then evaluates them.  Basically, it sources .bashrc and sets the new 
variables in emacs.  It works fine, but I want to be able to run it by
M-x read-environment

This doesn't work. I have to put
(read-environment)
into *scratch*, move to the ')' and do C-x C-e to evaluate it.  Pretty lame.

 From the digging around I've done, it seems like it should just work.  
Any ideas?  BTW, the defun is in my .emacs

Thanks
Matt
