# backup_mud.sh
# 4/7/97
# Zeran
# Written to backup source, areas, and players and store in 
# /home/admin/mudbackups/ appropriately.
# Usage:  backup_mud.sh [ all | source | area | player | other ]
# No argument defaults to choice "all"
# "all" makes backup of all mud source, player, and area files
# "source" makes backup of source files only
# "area" makes backup of area files only
# "player" makes backup of player files only
# 11/9/97
# Zeran
# Changed /home/admin/mudbackups to a mounted zip disk for security
# 4/26/98
# Zeran
# Modified for use with SunderMud ][
# Changed to use separate filesystem on harddrive...
# "other" option in usage...archives msgbase, data, and class directories
# 5/5/98
# Zeran
# Modified to create archive in area, player, and src directories so that
# the "../" portion of the path isn't put in the archive.
# 6/25/02
# Lotherius
# Removed some of Z's profanity :) Modified to work better with the new scripts.
# Specifically, modified it to read a config file of where to make the backups.
# Also set it up to create directories that don't exit... Duh.
