Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
pk2bm -V (return code: 1)
pk2bm: - illegal option
pk2bm -h (return code: 1)
Usage: pk2bm [-bh] {-c char|-o octchar} [-W width -H height] pkfile
