# This script is useful for burning the contents of the current
# directory to a CD.  It reduces the work of creating a normal
# data CD to just typing "danger-burn" and hitting ENTER twice.
#
# Note that if you are going to use this to create multi-session
# CDs, then you will want to run "cdrecord -dev=1,0,0 -msinfo" 
# first, to figure out which magic numbers to give mkisofs's -C
# argument.  See /usr/doc/cdrecord*/README.multi for more info.
