# ==================================
#
# Version 1.0.4 19th December 2015
#
# (C)2015 Dennis Ayala for BBSlink.net.
#
# Thanks go to haliphax for cryptography advice.
#
#
# USAGE:
# =====
#
# 1. Place this script in an appropriate directory that is
# accessible by your BBS software.
#
# 2. Configure the script with your system code, authorisation
# code and scheme code below.
#
# 3. Change permissions with the following command:
#
# chmod +x bbslink.sh
#
# 3. From the BBS door setup, call the script with the following command:
#
# bbslink.sh [door code] [user number]
#
# i.e. bbslink.sh lord 27
#
# 4. You can call different door games by changing the argument
# in the command line. An up-to-date list of available doors
# can always be found at http://www.bbslink.net/sysop
#
# I hope you find BBSlink.net useful. Please guard your BBSlink login
# credentials carefully, and should your system's authorisation code be
# compromised, please contact me immediately for a new one.
#
# All feedback is greatly appreciated!
#
# Mark Mearns.
