$PROGNAME $VERSION converts a MetaPost output file (.mps) to a self
contained EPS file. For best result, the MetaPost output file 
should not set "prologues".

Usage: $PROG [options] input.mps
        --dvips options     Sets addition DVIPS options, make sure to quote
                            arguments properly.
                            Example: $PROG -dvips "-N -V" file.mps
    -h, --help              This help message.
    -v, --version           Displays the version number
