27 # encode2mpeglight is a program that can create VCD/SVCD/DVD MPEGs
28 # and eventually extract VobSub subtitles from a DVD using only
29 # MEncoder/MPlayer.
30 #
31 # encode2mpeglight is a stripped release of encode2mpeg and therefore the
32 # code is redundant in several places, with many variables defined and
33 # used for no apparent reason. This cannot be avoided easily.
34 # A command line like:
35 # encode2mpeglight <encode2mpeglight options>
36 # will produce almost the same results as:
37 # encode2mpeg -mpeg -mpegonly <encode2mpeglight options>
38 #
39 # If you need more features like:
40 # - two or more audio streams, chapters, subtitles, menu
41 # - creation, burn and verification of the disk image
42 # - creation of MPEG-4 avi and subtitles for a hardware player
43 # and more, consider to use the full release (http://encode2mpeg.sf.net)
44 #
45 # encode2mpeglight is mainly tested with the stable release of MPlayer,
46 # I try to make it work with SVN too, but due to the "unstable" nature of
47 # SVN, bugs may suddenly appear. If you find any, please report them to me.
