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.
