Oops.  I agree this isn't how it should be.  Maybe Matthieu Moy can fix 
this, he's the one generating the tarballs.

This seems to be a bug, but it's not the cause of your problem.  I don't 
see this as a priority right now.

Presumably, the function `define-coding-system-alias' is undefined 
because your XEmacs is not MULE-enabled.  xmtn requires MULE to be able 
to decode UTF-8.  I'll clarify the readme file accordingly.

You could try rebuilding your XEmacs to enable MULE.

I only use GNU Emacs and have just tried xmtn in XEmacs for the first 
time, found a number of problems, and posted a patch to the dvc-dev 
mailing list with some fixes for XEmacs compatibility.  However, it's 
incomplete; I don't think it's usable yet.  I may be able to investigate 
XEmacs compatibility some more in a few weeks when I have more time.  Or 
maybe someone else can help.

I don't know how long it will take for the DVC snapshot to include this 
patch.

Good luck and thanks for the feedback.
Christian.
