Basically, I agree with Carlos that if should be called ff03ua if it is
really a "counterpart" to ff03.

Can you describe the extent to which the new ua force field is the
"counterpart" to ff03 itself? My understanding is that:

    ff03 = ff99 + new charges for amino acids
                + a few changes in backbone torsions

Is there a similar "simple" way to describe the new ua parameters?
