.SH DESCRIPTION
Calculate Z value (i.e. the number of "chemical formula units" in
the unit cell) using the provided cell volume, crystal density

\-\-use\-c\-parser
                  Use faster C/Yacc CIF parser. Default.


\-\-allow\-fractional\-z
                  Output also fractional Z values. They most probably
                  indicate errors, but might be needed for data checks.


\-\-disallow\-fractional\-z
                  Treat fractional Z values as errors. Default.


\-c, \-\-always\-continue
                  Continue processing and return successful return status
                  even if errors are diagnosed.

                  Do not terminate script if errors are raised.


\-\-die\-on\-errors
                  Terminate script immediately if errors are raised.
                  Default.


\-\-print\-header
                  Print TSV stream header (column names).


\-\-no\-header
                  Do not print TSV header. Default.


\-\-print\-datablock\-name

\-\-print\-data\-block\-name
                  Print the name of the data block and the file name.


\-\-no\-datablock\-name

\-\-no\-data\-block\-name
                  Do not print data block name. Default.


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

\-\-version
                  Output version information and exit.
