The hydrogen bond was never a separate term in the force field. About two
decades ago, there was a "10-12" term that was used to fine-tune hydrogen bond
energies, and I believe that this is what is weighted by "HB". Since this
term no longer exists in any modern Amber forcefield, this weighting option
is obsolete.
