"""\
usage: %s [-hvbf] [-d output-dir] [-i TTF-input-file] [TTX-file...]

    Translate a TTX file (as output by ttDump) to a TrueType font file. 
    If a 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:
    -h Help: print this message
    -i TrueType-input-file: specify a TT file to be merged with the TTX file.
       This option is only valid when at most one TTX file (or directory
       containing separated TTX files) is specified.
    -b Don't recalc glyph boundig boxes: use the values in the TTX file as-is.
    -d <output-dir> Specify a directory in which the output file(s)
       should end up. The directory must exist.
    -f Force overwriting existing files.
    -v Verbose: messages will be written to stdout about what is being done
