       --use-perl-parser
                         Use Perl parser for CIF parsing.

       --use-c-parser
                         Use Perl & C parser for CIF parsing.

       --compute-symops
                         Apply basis change to symmetry operators. Not all
                         lattices are processed correctly, thus this option
                         is experimental only and is turned off by default.

       --debug, --no-debug
                         Turn on/off the debug prints of reduction algorithm.
                         Default: off.

       --help, --usage
                         Output a short usage message (this message) and exit.

       --version
                         Output version information and exit.
