/* TMRevertUser: Trymedia Client User.

 * The code for Message() has been taken and adapted from Tony Smith's project:

 * http://public.perforce.com:8080/guest/tony_smith/perforce/p4u/main/?ac=83
 * 
 * Thanks to him, I did not need to fiddle around with this stuff.
 * 
 * 
 * This user hooks the Message() call to get the versioned paths of all reverted
 * files.
