XBoard

First of all, XBoard is the most popular open-source chessboard for Linux. I'm trying to get Xboard working on Edgy Eft. Xboard is looking for older versions of X11, like X11R4 and R5, but not R6 nor R7(Xorg?) I think I'll download it, Xorg source code, and if Xboard still doesn't work, then I'll personally try to upgrade the code. I don't know anything about X programming, and I could even try to write my own chessboard program for WxWidgets or Gtk+ if X11 programming documentation is not forthcoming.

Got XBoard to work with xorg, and it was easy! Just had to add a couple lines of code to XBoard's config.in, so that it would find xorg, and then recompiled config.in using autoconf.
