as fas as I can see, OPLS is currently not supported, but in principle everything 
you need about how to introduce a new forcefield should be in the gromacs manual 
(pdf and online), although this is not a trivial task of course. I think there have 
been attempts by others (David?) to include OPLS into gromacs, but those apparently 
haven't made it into the distributed version. As you've probably seen, there was 
recently a discussion in the gromacs users mailing list about inluding the AMBER 
forcefield. I'm therefore sending a copy of this to the list. Maybe somebody
wants to add/correct/contribute something?
