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.
automoc4 --version (return code: 0)
automoc4 --help (return code: 0)
Usage: automoc4 <outfile> <srcdir> <builddir> <moc executable> <cmake executable> [--touch]
