# Simple, configurable rsync backup script
#
# You define the command (rsync + path), the arguments, and what
#  to back up (and to where).  Supports multiple locations, via LOCX
#  variables.
# 
# If you call it with a '-q' flag, it will put the log in 
#  /var/log/backup.log; otherwise, it will write to stdout.
