[AUCTeX] How to tell auctex where LaTeX is?

[Dave Cook]

Hello,

In trying to mke my self hardware-portable as well as software portable, I 
have installed emacs, auctex and a LaTeX distribution (MikTex) on a 
Windows-readable HDD which I can carry round with me. It works OK but 
(knowing no elisp and not wishing to know much!) I don't know how to tell 
auctex where the LaTeX commands are by modifying the drop-down "command" 
menu so making the flow of work un-necessarily 
laborious.

Can anyone help? emacs, auctex and MikTex are all on the same disc - G: 
say.

Dave
