# Start GNU Chess, but have it use the xboard protocol.
# This makes it easy for programs (like xboard) to simply invoke
# "gnuchessx" and have it do the "right thing."

# The final parameter is more complicated to work around a
# bug in some old Unix-like systems; see the GNU autoconf documentation
# for the rationale.
