        Prints this help text.
	-i inputfilename
        Mandatory. Specify image file. Unless file proportions aren't 4:3 (or 3:4, depending on orientation), it will be cropped to meet this ratio.
    -o outputfilename
        Optional. Output file name. If omitted, 'motivator-' will be appended to input file name to produce output file name.
    -io imageorientation
        Optional. Desired image orientation, 'landscape' (750x600) or 'portrait' (600x750). Default: 'landscape'.
    -h text
        Optional. Header text. Default: none.
    -t text
        Optional. Term text. Default: none.
    -fd fontdir
        Optional. Directory the font files are located in. Default: '${vars{'fd'}}'.
    -wd workdir
        Optional. Directory used to store temporary files. Default: '${vars{'wd'}}'.
    -hf fontfilename
        Optional. Font file name used to write header. Default: ${vars{'hf'}}.
    -tf fontfilename
        Optional. Font file name used to write term. Default: ${vars{'tf'}}.
    -hfs fontsize
        Optional. Font size the header is written with. Default: ${vars{'hfs'}}.
    -tfs fontsize
        Optional. Font size the term is written with. Default: ${vars{'tfs'}}.
    -v verboselevel
        Optional. If 0, only fatal errors are displayed. If 1, the script is more talkative about what it's doing. Default: ${vars{'v'}}.
