			<UL><LI>N = # of atom types to use in this simulation
			<LI>region-ID = ID of region to use as simulation domain

			<P><B>Description:</B>
			</P>
			<P>This command creates a simulation box that encloses the specified
			region. Thus a <A HREF = "region.html">region</A> command must first be used to
			define a geometric domain. If the region is not of style <I>block</I>,
			LAMMPS encloses it with a rectangular simulation box.
			</P>
			<P>The argument N is the number of atom types that will be used in the
			simulation.
			</P>
			<P><B>Restrictions:</B>
			</P>
			<P>An <A HREF = "atom_style.html">atom_style</A> and <A HREF = "region.html">region</A> must have
			been previously defined to use this command.
