* (4) You may Distribute your Modified Version as Source (either gratis or for *
* a Distributor Fee, and with or without a Compiled form of the Modified       *
* Version) provided that you clearly document how it differs from the Standard *
* Version, including, but not limited to, documenting any non-standard         *

* the following:                                                               *

* (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     *
* Version.                                                                     *

* (ii) a license that permits the licensee to freely copy, modify and          *
* 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.                                                     *
* Aggregating or Linking the Package                                           *
*                                                                              *
* (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.             *
*                                                                              *
* (12) This license does not grant you the right to use any trademark, service *
* mark, tradename, or logo of the Copyright Holder.                            *

* (13) This license includes the non-exclusive, worldwide, free-of-charge      *
* patent license to make, have made, use, offer to sell, sell, import and      *
* otherwise transfer the Package with respect to any patent claims licensable  *

* you institute patent litigation (including a cross-claim or counterclaim)    *
* against any party alleging that the Package constitutes direct or            *
* contributory patent infringement, then this Artistic License to you shall    *
* terminate on the date that such litigation is filed.                         *
*                                                                              *
