; These constraints are used for vsite constructions as generated by pdb2gmx.
; Values depend on the details of the forcefield, vis. bondlengths and angles
-; These parameters are designed to be used with the GROMACS forcefields
-; ffgmx and ffgmx2 and with the GROMOS96 forcefields G43a1, G43a2 and G43b1.

; Constraints for the rigid NH3/CH3 groups depend on the hygrogen mass,
; since an increased hydrogen mass translates into increased momentum of
