Actually it uses some information from REMARK records (if it finds it 
and validates it is good, otherwise continues), such as TLS selections, 
twin operator, perhaps something else which I forgot.

Recently it started outputting LINK records for internally generated 
extra restraints, such as metal coordination or ligand linking. I can't 
remember if we read them back and if we do what happens if LINK defines 
nonexistent (obsolete) atoms.
