documentation on TIP4 will be included in the 2.7 release, but the code
is there in 2.7b1. I'll send you some sample files off list. I do not
expect the implementation in its present form to work with gromacs
formatted topologies; only charmm formatted. In 2.7b1 the only dummy
atom code is for the TIP4 (and related water model) lone pair, but some
more general code is currently in the works.
