	<P><B>Description:</B>
	</P>
	<P>Zero out the force and torque on a granular particle. This is useful
	for preventing certain particles from moving in a simulation.
	</P>
	<P><B>Restrictions:</B>
	</P>
	<P>Can only be used if LAMMPS was built with the "granular" package.
	</P>
	<P>There can only be a single freeze fix defined. This is because other
	parts of the code (pair potentials, thermodynamics, etc) treat frozen
	particles differently and need to be able to reference a single group
	to which this fix is applied.
