Usage: ${0##*/} [-hv] [-s STARTING TITLE] [-e ENDING TITLE] [-o OUTFILE OFFSET] [-f OUTFILE] [FILE]...
    Export titles from FILE to OUTFILE, FILE should be a .iso format.

    -h          display this help and exit
    -f OUTFILE  name out output file, DEFAULTS to the input FILE.mkv
    -s #        starting title, DEFAULT 1
    -e #        ending title, DEFAULTs to last title
    -o #        offset the exported title to this, useful when dealing
                with multi dvd seasons. This option also forces OUTFILE##.mkv behaviour.
    -i          inspect the .iso and lists title index, lengths and total title counts.

./iso2mkv.sh -e 4 -f SomeShowSeason1E  dvd.iso
..exports titles 1 - 4 to files SomeShowSeason1E{01-04}.mkv

./iso2mkv.sh -s 5 -e 10 dvd.iso
..exports titles 5 - 10 to files  dvd{05-10}.mkv

./iso2mkv.sh -e 10 -o 11 dvd2.iso
..exports titles 1 - 10 to files  dvd2{11-20}.mkv

./iso2mkv.sh -e 1 dvd.iso
..exports titles 1 as dvd.mkv
