1. Don't be afraid to experiment and see what happens with your system.
2. Look at leaprc.water.spce for the recommended commands. The idea
    there is to (try to) avoid all the commands listed above. Just type
    "source leaprc.water.spce"

3. If there are no HOH residues in your system, then setting HOH=SPC has
    no effect. (But as suggested in point 1: try it out!)
