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