 * If you would like to use major pieces of RasMol in some other program,  *
 * make modifications to RasMol, or in some other way make what a lawyer   *

 *   * 4. Please explain in your documentation how what you did differs    *
 *     from this version of RasMol; and                                    *
 *   * 5. Please make your modified source code available.                 *
