X11 configuration

X11 configuration can change the X11 NetHack windowport window background and text colors, fonts and other things. You can either directly edit the NetHack.ad in the playground or you can create a file which can contain the configuration lines, and then do xrdb -merge file.

The configuration file that comes with NetHack sources, win/X11/NetHack.ad contains extensive documentation about the file and what you can change in it. This file is copied to the nethack playground when compiling and installing from source.
