The following automatic conversions were performed:

'_atom_sites_solution_primary' value 'Other' changed to 'other'
according to
/usr/data/users/saulius/crontab/automatic-downloads/rss-feeds/ACS/lib/dictionaries/cif_core.dic
dictionary named 'cif_core.dic' version 2.4.2 from 2011-04-26.

'_exptl_crystal_density_meas' value 'not measured' was changed to '?'
- the value is perceived as not measured.

The following automatic conversions were performed:
'_symmetry_space_group_number' data item was removed -- it should
have been renamed to '_space_group_IT_number' as specified in the
replacement file
'/home/antanas/src/cod-tools/trunk/data/replacement-values/replacement_tags.lst',
but the replacement data item was already present in the data block
and had the same value as the '_symmetry_space_group_number' data
item.
