Where to get X-plor (fwd)

Our research group is mainly interested in deuterium NMR of lipid membrane
systems.  However, our current research involves studies of helical
peptides involved in transmembrane conduction using NMR as the principle
tool of investigation.  We have been considering doing molecular dynamics
simulations of lipid-peptide systems as a complement to our current
research.  I have read several articles where people use X-plor for the
molecular dynamics simulations of systems similar to those which we are
interested.  Does CNS still employ CHARMM force field  parameter files as
did the X-plor software?  If so, CNS may be the route I will follow.  I
know that CHARMM has a special lipid parameter set for simulation of
bilayer systems.
