CIF parser / dialects (was Re: Another suggestion for the BNF)

If there is a concern over CIF dialects the easiest way to allay that concern and inhibit present and future dialects is to provide an IUCr sponsored parser. It should be in C and easily interfaced with the usual development languages (C (and its relatives), Perl, Python, Tcl, FORTRAN). Such a parser would conform to the IUCr specs. for reading/writing CIFs and thereby form a solid base for higher level tools. The situation we have now, with so many disparate parsers, is not very satisfactory (I have a partial one in Perl, James Hester has his in Python, there's Syd's & Herb's in FORTRAN and I am sure many others as well) and really should be addressed.

If I have missed the creation of such a full-fledged, IUCr-approved, C-based parser I would appreciate a pointer to the code and I apologize for the misunderstanding.
