###############################################################################
# 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.
