usage: %s [-hvb] [-i TrueType-input-file] TTX-file [TrueType-output-file]
    Translate an TTX file (as output by ttDump.py) to a TrueType font file. 
    If the TTX-file argument is a directory instead of a file, all files in
    that directory ending in '.ttx' will be merged into one TrueType file. 
    This is mostly useful in conjunction with the -s option of ttDump.py.

    Options:
    -i TrueType-input-file: specify a TT file to be merged with the TTX file(s)
    -v verbose: messages will be written to stdout about what is being done
    -b Don't recalc glyph boundig boxes: use the values in the TTX file as-is.
    -h help: print this message
