mmCQL - SQL-like tool to manipulate mmCIF files

       Written by Maarten L. Hekkelman <maarten@hekkelman.com>

       The mmCIF format is a structured format and with a proper dictionary it even looks a lot like a database
       with relations between categories that act as tables.

       In pipelines processing mmCIF files it is often required to simply change the content of a single field,
       or add some data, delete it, etc. For this the mmCQL tool offers a SQL like language.

       This tool is not a complete and finished piece of software, it lack perhaps a lot of functionality.
       However, it is already very useful to simply lookup some value or change items based on some criteria.

       You can do simple updates, like so:

       UPDATE struct_asym SET id = 'X' WHERE id = 'BBB';

       This  will rename the asym with ID 'BBB' to 'X'. All children of this asym will be renamed as well if the
       proper dictionary was loaded.

--force
              Write output file even if the name of the output file is the same as the input file, which will of
              course overwrite the input file.

       --script=<file>, -f <file>
              Read commands from the file <file.

       --verbose,-v
              Be more verbose, useful to diagnose validation errors.
