+#!/bin/bash
+# This script dumps the specified Filesystem via dump on a CD/DVD
+# CD_CAPACITY defines the capacity in MB per CD
+# The script for the next volume is passed via the -F option of dump
+# At least for my DVD-Recorder (a PHILIPS DVR-A03) it is necessary
+# to define the tracksize for the next track before the DVD is written.
+# This is done via the -tsize option of cdrecord. Since tsize takes its
+# arguments in Bytes, the shell cannot compute the value correctly
+# anymore (value too high), so I use bc.
+
+# !!! If you plan to write DVD's with other sizes, please correct the
+# CD_CAPACITY in the dump_userexit_DVD script, too !!!
