# File: make-standalone.sh
#
# Description:
#    even after make-distribution.sh bashbot is not self contained as it was in the past.
#
# Options: --notest
#
#   If you your bot is finished you can use make-standalone.sh to create the
#    the old all-in-one bashbot:  bashbot.sh and commands.sh only!
#
