cif_filter - parse a CIF file and print out essential data values in the CIF format, the
COD CIF style. This script has also many capabilities -- it can restore space group
symbols from symmetry operators (consulting predefined tables), parse and tidy-up

SYNOPSIS
cif_filter --options input1.cif input*.cif
DESCRIPTION
Parse a CIF file and print out essential data values in the CIF format, the COD CIF style.
This script has also many capabilities -- it can restore space group symbols from symmetry
operators (consulting predefined tables), parse and tidy-up _chemical_formula_sum, compute
cell volume, exclude unknown or "empty" tags, and add specified bibliography data.
OPTIONS
-a, --authors 'John Doe; Jane Doe; Joe Bloggs'
-j, --journal 'Acta Cryst. A'

Specify bibliographic data to be included into the output.
-B, --bibliography bibliography.cif
--bibliography bibliography.mrk
Provide a bibliography file with the bibliographic
information to be included into the output. The
bibliography information can be provided in CIF format
or in a XML-like .mrk file with data items between
<authors>, <journal>, <volume>, <issue>, <year>,
<pages>123-132</pages> tags.
--leave-bibliography
Combine bibliographies from various sources. Values of lower
precedence are overwritten, but never deleted. List of
bibliography sources in order of increasing precedence:
1) the bibliography tags of the original CIF file;
2) the optional bibliography file;
3) the user specified command line options.
--discard-bibliography
Only retain the bibliography tags from the bibliography
source of highest precedence (see '--leave-bibliography'
option) (default).
