   8 # Script used to dump to a remote box with a CD-Burner. There is a
   9 # companion script called get-dumpdata-to-cdrecord.
  10 #
  11 # Usage: dump-to-remote-cd [ -c <CD_capacity> ] [files to dump ...]
  12 #
  13 # If called without arguments, it will dump / assuming 650 MB Media on
  14 # host kiki (see DEFAULT_ below).
  15 #
  16 # You must be able to do an rsh as root to BURN_HOST and vice versa,
  17 # see get-dumpdata-to-cdrecord. You may use ssh instead.
