The following is the current version of my rook game, called Raven. It is a work in progress, in the sense that it's not finished yet. (I'm not still working on it.) The source code package is provided if you want to run it on Linux. It compiles like most any Gnome Linux program. I am also working on a Windows version, whose source is in the same package. The Windows program is available already compiled in a separate package.
