###############################################################################
#   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 SVN too, but due to the "unstable" nature of
#   SVN, bugs may suddenly appear. If you find any, please report them to me.
