The Resp program (Restrained ElectroStatic Potential) [1,2]
used for deriving charges for the Cornell et al. "new AMBER" 
force field [3] is now freely available at our web and ftp sites:

Included in the tar are a new utility program with instructions 
by James Caldwell to simplify getting the input ESP grid from
Gaussian94, and a script and instructions for use with GAMESS
contributed by Hans De Winter.
