176467 (current)	2016-02-16	cif/ (antanas@kurmis) Replacing _[local]_cod_* tags with their equivalents from the COD CIF dictionary in multiple entries in range 4.	4310604.cif
134621	2015-04-02	The 'cif_fix_values' script with an option '--fix-only-weighting-scheme' and 'cif_filter' script were run over CIF files which included an incorrect value of the data item '_refine_ls_weighting_scheme'. Read the log for more details. There were more than 18k CIF files with values to modify. Usually these incorrect values include comment with formulas, but values of this data item must be an enumerator. The script creates new data item '_refine_ls_weighting_details' to store these comments with formulas, and writes the enumerator 'calc' as a value of data item '_refine_ls_weighting_scheme'. There exists some exceptions in the script.	4310604.cif

34330	2012-02-24	cif/4/ Reorganising CIF range 4 into a prefix tree.	4310604.cif
17004	2011-03-31	cif/ Commiting CIFs, that were updated with the 'cif_fix_values' script, using options '--fix-misspelled replacement_values.lst', '--fix-temperature' and '--fix-enums' with built-in table of enum values. The following cmd was used: > (set -x; find ? -name \*.cif \| sort \| xargs -i sh -c 'if !( > cif_fix_values --fix-misspelled ~/../inputs/replacament_values.lst {} \| > cif_filter --add-cif-header {} \| > sponge {} ) 2>&1 \| grep NOTE; then svn revert {}; > fi' ) &	4310604.cif
5312	2011-01-03	cif/ Adding files, updated with the 'cif_fix_enum' program and the cif_core.dic dictionary. The enumerator values were fixed, mostly incorrect case, but also some values that had extra underscores, dashes or spaces. Unfortunately, 22 had non-ASCII characters with the 8-th bit set, and these got incorrectly interpreted as latin1 characters and converted to their UTF8 equivalents by Perl. To fix the structures, however, they need to be redeposited from the original files with the new CIFParser/cif_filter version.	4310604.cif
