Emacs v XEmacs in ports

[Peter Gammie]

Hello,

I'm new to this list, so I apologise if my question has already been  
addressed.

I want to install Mozart, so I do the usual:

% sudo port install mozart

which results in port trying to install Emacs, when there is already  
a perfectly usable XEmacs installed, which a quick Google implies  
Mozart should be happy with.

No worries, just change the port in the obvious way:

% sudo port edit mozart
...

and off it goes.

Now, is this the thing to do? Also, is there a way to change the  
portfile so it has - perhaps as variants - Emacs and XEmacs  
alternatives?

thanks,
Peter.
