+# Description: This script wraps a number of linux utilities to
+# create a recipe for ripping protected DVDs, circumventing
+# ARcoSS and CRC checksum error protection schemes used on many
+# newer DVDs. Edit as appropriate for your needs. I use this to
+# backup DVDs I own, and do not condone any other activity it
+# may be used for.
+#
+# Known Issues/Limitations:
+# - Mirror mode is always done in ISO mode
+#
+# Package Dependencies:
+# lsdvd dvdauthor gddrescue dvdbackup makexml tovid mencoder vlc mplayer genisoimage
+#
+# Optional Dependencies:
+# lookup imdb info/posters for mythvideo: http://www.mythtv.org/wiki/Fill_mythvideo_metadata.pl
