Look in $AMBERHOME/dat/leap/lib/solvents.cmd. You can make changes there,
then re-run this through tleap ("tleap -f solvents.cmd") to create a new
solvents.lib file, which can then be loaded into tleap.

(Keep a backup copy of the original solvents.cmd and solvents.lib files, or
modify solvents.cmd to write its output to a new filename.)

...good luck...dac
