+c "sizes.i" sets values for critical array dimensions used
+c throughout the software; these parameters will fix the size
+c of the largest systems that can be handled; values too large
+c for the computer's memory and/or swap space to accomodate
+c will result in poor performance or outright failure
+c
+c parameter: maximum allowed number of:
+c
+c maxatm atoms in the molecular system
+c maxval atoms directly bonded to an atom
+c maxgrp user-defined groups of atoms
+c maxtyp force field atom type definitions

+c maxkey lines in the keyword file
+c maxrot bonds for torsional rotation
+c maxvar optimization variables (vector storage)
+c maxopt optimization variables (matrix storage)
+c maxhess off-diagonal Hessian elements
+c maxlight sites for method of lights neighbors
+c maxvib vibrational frequencies
+c maxgeo distance geometry points
+c maxcell unit cells in replicated crystal
+c maxring 3-, 4-, or 5-membered rings
+c maxfix geometric restraints
+c maxbio biopolymer atom definitions
+c maxres residues in the macromolecule
+c maxamino amino acid residue types
+c maxnuc nucleic acid residue types
+c maxbnd covalent bonds in molecular system
