The following automatic conversions were performed:

'_chemical_melting_point' value '234_C' was changed to '507.15' - it
was converted from degrees Celsius(C) to
Kelvins(K).

'_symmetry_cell_setting' value 'Orthorhombic' changed to
'orthorhombic' according to
/home/saulius/struct/CIF-dictionaries/cif_core.dic dictionary named
'cif_core.dic' version 2.4.1 from 2010-06-29.
