	I think the ``easily'' in the original messages distinguishes the 
possibility from direct support.  undo is cool functionality in that it 
I can make a large number of changes around a tree and decide it was a 
waste and revert them all.  That's something I can't do easily in 
perforce (but I can script it on the cases where I need it).  I usually 
undo individual files, though.

	file-revert has been extremely useful to me.  Has there been any 
further thought on importing it into tla?  It was originally rejected 
because of a build problem I've been unable to reproduce (I use arch on 
MacOS X, NetBSD, Linux, and Solaris from my tree), along with some 
coding standards issues I've fixed up.  If there's a build problem, I'd 
like to know more about it.  I've been keeping my tree up-to-date with 
the head of line changes (it's up to 
address@hidden/tla--devo--1.1--patch-249 right now).

	I've seen mention of an undo with limits that might obsolete this 
functionality, but I've not seen that work.
