An X Window System Chess Board
XBoard is a graphical chessboard that can serve as a user interface
for GNU Chess, for the Internet Chess Server, or for electronic mail
correspondence chess. XBoard can also be used by itself.
XBoard uses the Helvetica font (located in the xfonts-75dpi and
xfonts-100dpi packages) by default. However, other fonts can be
specified via a command line option or an X resource.
