Hi Danilo,

I thought about this some (sorry for the delay in responding), but I just 
don't see a picture in which such a framework would be useful.  There are 
many different types that could be considered for inclusion, but what 
check is needed is frequently specific to the code in question.  I don't 
see enough reusability to warrant a set of library routines.
