|  | *   of the Copyright Holder as specified below.                                * | ||

|  | *   basis of media cost, duplication charges, time of people involved,         * | ||
|  | *   and so on.  (You will not be required to justify it to the                 * | ||
|  | *   Copyright Holder, but only to the computing community at large             * | ||
|  | *   as a market that must bear the fee.)                                       * | ||

|  | * 2. You may apply bug fixes, portability fixes and other modifications        * | ||
|  | * derived from the Public Domain or from the Copyright Holder.  A Package      * | ||
|  | * modified in such a way shall still be considered the Standard Version.       * | ||

|  | * 3. You may otherwise modify your copy of this Package in any way, provided   * | ||
|  | * that you insert a prominent notice in each changed file stating how and      * | ||
|  | * when you changed that file, and provided that you do at least ONE of the     * | ||
|  | * following:                                                                   * | ||

|  | *    a) place your modifications in the Public Domain or otherwise make them   * | ||
|  | *    Freely Available, such as by posting said modifications to Usenet or      * | ||
|  | *    an equivalent medium, or placing the modifications on a major archive     * | ||
|  | *    site such as uunet.uu.net, or by allowing the Copyright Holder to include * | ||
|  | *    your modifications in the Standard Version of the Package.                * | ||
|  | *                                                                              * | ||
|  | *    b) use the modified Package only within your corporation or organization. * | ||

|  | *    c) rename any non-standard executables so the names do not conflict       * | ||
|  | *    with standard executables, which must also be provided, and provide       * | ||
|  | *    a separate manual page for each non-standard executable that clearly      * | ||
|  | *    documents how it differs from the Standard Version.                       * | ||
|  | *                                                                              * | ||
|  | *    d) make other distribution arrangements with the Copyright Holder.        * | ||
|  | *                                                                              * | ||
|  | * 4. You may distribute the programs of this Package in object code or         * | ||
|  | * executable form, provided that you do at least ONE of the following:         * | ||
|  | *                                                                              * | ||
|  | *    a) distribute a Standard Version of the executables and library files,    * | ||
|  | *    together with instructions (in the manual page or equivalent) on where    * | ||
|  | *    to get the Standard Version.                                              * | ||
|  | *                                                                              * | ||
|  | *    b) accompany the distribution with the machine-readable source of         * | ||
|  | *    the Package with your modifications.                                      * | ||
|  | *                                                                              * | ||
|  | *    c) give non-standard executables non-standard names, and clearly          * | ||
|  | *    document the differences in manual pages (or equivalent), together        * | ||
|  | *    with instructions on where to get the Standard Version.                   * | ||
|  | *                                                                              * | ||
|  | *    d) make other distribution arrangements with the Copyright Holder.        * | ||
|  | *                                                                              * | ||
|  | * 5. You may charge a reasonable copying fee for any distribution of this      * | ||
|  | * Package.  You may charge any fee you choose for support of this              * | ||
|  | * Package.  You may not charge a fee for this Package itself.  However,        * | ||
|  | * you may distribute this Package in aggregate with other (possibly            * | ||
|  | * commercial) programs as part of a larger (possibly commercial) software      * | ||
|  | * distribution provided that you do not advertise this Package as a            * | ||
|  | * product of your own.  You may embed this Package's interpreter within        * | ||
|  | * an executable of yours (by linking); this shall be construed as a mere       * | ||
|  | * form of aggregation, provided that the complete Standard Version of the      * | ||
|  | * interpreter is so embedded.                                                  * | ||
|  | *                                                                              * | ||
|  | * 6. The scripts and library files supplied as input to or produced as         * | ||
|  | * output from the programs of this Package do not automatically fall           * | ||
|  | * under the copyright of this Package, but belong to whoever generated         * | ||
|  | * them, and may be sold commercially, and may be aggregated with this          * | ||
|  | * Package.  If such scripts or library files are aggregated with this          * | ||
|  | * Package via the so-called "undump" or "unexec" methods of producing a        * | ||
|  | * binary executable image, then distribution of such an image shall            * | ||
|  | * neither be construed as a distribution of this Package nor shall it          * | ||
|  | * fall under the restrictions of Paragraphs 3 and 4, provided that you do      * | ||
|  | * not represent such an executable image as a Standard Version of this         * | ||
|  | * Package.                                                                     * | ||
|  | *                                                                              * | ||
|  | * 7. C subroutines (or comparably compiled subroutines in other                * | ||
|  | * languages) supplied by you and linked into this Package in order to          * | ||
|  | * emulate subroutines and variables of the language defined by this            * | ||
|  | * Package shall not be considered part of this Package, but are the            * | ||
|  | * equivalent of input as in Paragraph 6, provided these subroutines do         * | ||
|  | * not change the language in any way that would cause it to fail the           * | ||
|  | * regression tests for the language.                                           * | ||
|  | *                                                                              * | ||
|  | * 8. Aggregation of this Package with a commercial distribution is always      * | ||
|  | * permitted provided that the use of this Package is embedded; that is,        * | ||
|  | * when no overt attempt is made to make this Package's interfaces visible      * | ||
|  | * to the end user of the commercial distribution.  Such use shall not be       * | ||
|  | * construed as a distribution of this Package.                                 * | ||
|  | *                                                                              * | ||
|  | * 9. The name of the Copyright Holder may not be used to endorse or promote    * | ||
|  | * products derived from this software without specific prior written           * | ||
|  | * permission.                                                                  * | ||
|  | *                                                                              * | ||
