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.
dwww-txt2html --version (return code: 0)
dwww-txt2html: couldn't open file `--version' for reading: No such file or directory
dwww-txt2html --help (return code: 0)
dwww-txt2html: couldn't open file `--help' for reading: No such file or directory
