+#   encode2mpeglight is a program that can create VCD/SVCD/DVD mpegs
+#   and eventually extract VobSub subtitles from a DVD using only
+#   MEncoder/MPlayer.
+#
+#   encode2mpeglight is a stripped release of encode2mpeg and therefore the
+#   code is redundant in several places, with many variables defined and
+#   used for no apparent reason. This cannot be avoided easily.
+#   A command line like:
+#     encode2mpeglight <encode2mpeglight options>
+#   will produce almost the same results as:
+#     encode2mpeg -mpeg -mpegonly <encode2mpeglight options>
+#
+#   If you need more features like:
+#     - two or more audio streams, chapters, subtitles, menu
+#     - creation, burn and verification of the disk image
+#     - creation of MPEG-4 avi and subtitles for a hardware player
+#   and more, consider to use the full release (http://encode2mpeg.sf.net)
+#
+#   encode2mpeglight is mainly tested with the stable release of MPlayer,
+#   I try to make it work with CVS too, but due to the "instable" nature of
+#   CVS, bugs may suddenly appear. If you find any, please report it to me.
