This is IQmol, a molecular builder and visualization package written by Andrew
Gilbert.  IQmol is able to build molecules, set up and submit input for Q-Chem
calculations, and analyse the output.  Analyses include display of molecular
surfaces (densites, molecular orbitals) and animations of frequencies and
reaction pathways.
