# ===========================
# By:          Eric Hameleers <alien@slackware.com>
# For:         gogui
# Descr:       GUI to programs that play the board game Go
# URL:         http://gogui.sourceforge.net/
# Needs:       a Go engine like pachi or gnugo
# Needs:       ant (build-time)
# Changelog:   
# 1.4.6-1:     26/Oct/2012 by Eric Hameleers <alien@slackware.com>
#              * Initial build.
# 
# Run 'sh gogui.SlackBuild' to build a Slackware package.
# The package (.tgz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'. 
#
