x-popup-menu
Folks,
Anybody like to comment on this? I wrote it with the intention it would
eventually get into the fsf-compat package.
I would definitely make porting of some packages much easier.
It's worked pretty well on the couple of popup I've tried but that
certainly isn't a very comprehensive collection.
