 * Please read the file NOTICE for important notices which apply to this   *
 * package. If you are not going to make changes to RasMol, you are not    *
 * only permitted to freely make copies and distribute them, you are       *
 * encouraged to do so, provided you do the following:                     *
 *   * 1. Either include the complete documentation, especially the file   *
 *     NOTICE, with what you distribute or provide a clear indication      *
 *     where people can get a copy of the documentation; and               *
 *   * 2. Please give credit where credit is due citing the version and    *
 *     original authors properly; and                                      *
 *   * 3. Please do not give anyone the impression that the original       *
 *     authors are providing a warranty of any kind.                       *
 *                                                                         *
 * 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   *
 * would call a "derived work", you are not only permitted to do so, you   *
 * are encouraged to do so. In addition to the things we discussed above,  *
 * please do the following:                                                *
 *   * 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.                 *
 *                                                                         *
 * This version of RasMol is not in the public domain, but it is given     *
 * freely to the community in the hopes of advancing science. If you make  *
 * changes, please make them in a responsible manner, and please offer us  *
 * the opportunity to include those changes in future versions of RasMol.  *
