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.
units_cur --help (return code: 1)
Usage: /usr/bin/units_cur [filename]
Update currency information for 'units' into the specified filename or if no
filename is given, the default: '/usr/share/units/currency.units'.
