NetHack/wins is a set of three patches to NetHack 3.3.1 which add the windowing systems derived from Slash'EM.
Patch 1 is required for either of the other two, but there are no other dependencies.
NetHack/wins is currently in the very early stages of development. I've done some very basic testing of playing a game under the GTK interface with all three patches applied, but that's about it.
I know there are lots of Slash'EM bits and bobs still present, especially in the Guidebook, which needs some major work.
Having said that, if you do find any bugs I'd appreciate it if you would drop me a note. I can be reached at firstname.lastname@example.org.
