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.
dccleancrw -V (return code: 1)
--version is not a CRW file!
dccleancrw (return code: 1)
Usage: dccleancrw crw_0001.crw crw_0002.crw ...
