There is no "Compatibility Guide" and I wish the documentation didn't  
refer to it.

As far as I can tell whenever I get that warning the package or  
function I am using has been superseded by another in version 6 but  
it's not trivial to find the replacement.  In this case after two  
false starts, I started looking at the documentation of FindRoot  
since that's related to the function in NumericalMath`IntervalRoots`,  
in the See Also section I noticed a function named RootIntervals but  
it doesn't seem as general as the functions in IntervalRoots since it  
only works on polynomials.

Perhaps IntervalRoots is using functions internally that have been  
superseded by others and hasn't been updated yet, so the message is  
essentially harmless.

Regards,

Ssezi
