RanGenConf (rgc): random generation of solvent configurations
The rgc (RanGenConf) program generates a configuration of molecules that are randomly oriented in space. It will put the first molecule (the solute if present) in the center of the system, and then will put the other molecules at random orientations around it.
The RanGenConf procedure is described in more detail in:

New in the 2007.01 release is the automatic adjustment of the overlap parameter,
in order to fit the molecules into the box.
Therefore, one has to specify only the desired (macroscopic) density.
