Actually it was more of a matter of hacking something together in an
evening to get mouse input working. Using GPM to do that seemed a good
idea at the time, but in retrospect I'd like to implement a few simple
native drivers for the most common mouse types as well. That way we can
cleanly support wheel mice and other more-than-three-button types of mice,
allow Nano-X to play nicely on a system that is also running XFree86
(actually, you can already do that if you tell X to use the repeater, but
again that doesn't work for wheel mice), and remove the uglyness of
having two mouse drivers one on top of the other, with one of them
running as a seperate process to the windowing system. If you've ever
tried hacking GPM, you'll know it's not the cleanest of programs either.
