Re: [ddlm-group] Relationship asmong CIF2, STAR, CIF1 and Python

Your "who knows" question is the core of my problem
with what we have done up until now.  It appears
that nobody knows what does or will constitute
STAR compatibility, and that it is doubful that
CIF1, much less CIF2 is compatible with any
version of STAR.
