Re: Revised statement of policy on CIF

Brian raises a good point with respect to "Software claiming to READ...".

What about a changing this to:  Software claiming compliance with 
the IUCr CIF standard should be able ..."   I think that this is 
more precise and lets the casual CIF user off the hook.. 

Otherwise, I agree that this is a much friendly statement.
