# Slackware build script for maelstrom

# Written by B. Watson (yalhcru@gmail.com)

# Note to 64-bit users: Maelstrom-netd and the -server option to Maelstrom
# do not work correctly. I haven't investigated why. You can still play
# networked games in non-server mode (see man page). Users of actual
# Slackware are not affected by this.
