REVISION NOTES
This is version 6.0.1 of xbattle, by Mike Mayer, based on the version
5.4.1 by Greg Lesher. Much has changed in software developement since
this game was released in 1991. Unfortunatey, this has made xbattle
uncompilable on many platforms. This is a rewrite of 5.4.1 in C++11.
As with the original, it requires the X11 library (and headers).
Unlike the original, it also requires STL (the standard template library).
