# Description: This script wraps a number of linux utilities to
# create a recipe for ripping protected DVDs, circumventing
# Known Issues/Limitations:
# - Mirror mode is always done in ISO mode
#
-# Package Dependencies (apt-get install these for example):
-# lsdvd dvdauthor gddrescue dvdbackup tovid mencoder mplayer genisoimage libdvdcss2
-#
-# Specific Executable (program) Dependencies (must be found in $PATH):
-# volname makexml lsdvd dvdauthor gddrescue dvdbackup mencoder mplayer mkisofs HandBrakeCLI
-#
-# Optional Dependencies:
-# lookup imdb info/posters for mythvideo: http://www.mythtv.org/wiki/Fill_mythvideo_metadata.pl
-#
+# See the README file for information about the dependencies
+# this script has.
