|  | * (a) make the Modified Version available to the Copyright Holder of the       * | ||
|  | * Standard Version, under the Original License, so that the Copyright Holder   * | ||
|  | * may include your modifications in the Standard Version.                      * | ||
|  | * (b) ensure that installation of your Modified Version does not prevent the   * | ||
|  | * user installing or running the Standard Version. In addition, the Modified   * | ||
|  | * Version must bear a name that is different from the name of the Standard     * | ||

|  | * redistribute the Modified Version using the same licensing terms that apply  * | ||
|  | * to the copy that the licensee received, and requires that the Source form of * | ||
|  | * the Modified Version, and of any works derived from it, be made freely       * | ||
|  | * available in that license fees are prohibited but Distributor Fees are       * | ||
|  | * allowed.                                                                     * | ||

|  | * (5) You may Distribute Compiled forms of the Standard Version without the    * | ||
|  | * Source, provided that you include complete instructions on how to get the    * | ||
|  | * Source of the Standard Version. Such instructions must be valid at the time  * | ||
|  | * of your distribution. If these instructions, at any time while you are       * | ||
|  | * carrying out such distribution, become invalid, you must provide new         * | ||
|  | * instructions on demand or cease further distribution. If you provide valid   * | ||
|  | * instructions or cease distribution within thirty days after you become aware * | ||
|  | * that the instructions are invalid, then you do not forfeit any of your       * | ||
|  | * rights under this license.                                                   * | ||

|  | * (6) You may Distribute a Modified Version in Compiled form without the       * | ||
|  | * Source, provided that you comply with Section 4 with respect to the Source   * | ||
|  | * of the Modified Version.                                                     * | ||

|  | * (7) You may aggregate the Package (either the Standard Version or Modified   * | ||
|  | * Version) with other packages and Distribute the resulting aggregation        * | ||
|  | * provided that you do not charge a licensing fee for the Package. Distributor * | ||
|  | * Fees are permitted, and licensing fees for other components in the           * | ||
|  | * aggregation are permitted. The terms of this license apply to the use and    * | ||
|  | * Distribution of the Standard or Modified Versions as included in the         * | ||
|  | * aggregation.                                                                 * | ||

|  | * (8) You are permitted to link Modified and Standard Versions with other      * | ||
|  | * works, to embed the Package in a larger work of your own, or to build        * | ||
|  | * stand-alone binary or bytecode versions of applications that include the     * | ||
|  | * Package, and Distribute the result without restriction, provided the result  * | ||
|  | * does not expose a direct interface to the Package.                           * | ||
|  | * Items That are Not Considered Part of a Modified Version                     * | ||

|  | * (9) Works (including, but not limited to, modules and scripts) that merely   * | ||
|  | * extend or make use of the Package, do not, by themselves, cause the Package  * | ||
|  | * to be a Modified Version. In addition, such works are not considered parts   * | ||
|  | * of the Package itself, and are not subject to the terms of this license.     * | ||
|  | * General Provisions                                                           * | ||

|  | * (10) Any use, modification, and distribution of the Standard or Modified     * | ||
|  | * Versions is governed by this Artistic License. By using, modifying or        * | ||
|  | * distributing the Package, you accept this license. Do not use, modify, or    * | ||
|  | * distribute the Package, if you do not accept this license.                   * | ||
|  | *                                                                              * | ||
|  | * (11) If your Modified Version has been derived from a Modified Version made  * | ||
|  | * by someone other than you, you are nevertheless required to ensure that your * | ||
|  | * Modified Version complies with the requirements of this license.             * | ||

|  | * against any party alleging that the Package constitutes direct or            * | ||
