|
|
|
|
|
* Permission for Use and Modification Without Distribution *
|
|
|
|
|
* *
|
|
|
|
|
* (1) You are permitted to use the Standard Version and create and use *

|
|
|
|
|
* not Distribute the Modified Version. *
|
|
|
|
|
* Permissions for Redistribution of the Standard Version *
|
|
|
|
|
* *
|
|
|
|
|
* (2) You may Distribute verbatim copies of the Source form of the Standard *

|
|
|
|
|
* for a Distributor Fee, provided that you duplicate all of the original *

* *
|
|
|
|

|
|
|
|
* Version) provided that you clearly document how it differs from the Standard *
|
|
|
|
|
* Version, including, but not limited to, documenting any non-standard *
|
|
|
|
|
* features, executables, or modules, and provided that you do at least ONE of *
|
|
|
|
|
* 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. *
|
|
|
|
|
* (c) allow anyone who receives a copy of the Modified Version to make the *
|
|
|
|
|
* Source form of the Modified Version available to others under *
|
|
|
|
|
* (i) the Original License or *
|
|
|
|
|
* (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. *
|
|
|
|
|
* Distribution of Compiled Forms of the Standard Version or Modified Versions *
|
|
|
|
|
* without the Source *
|
|
|
|
|
* *
|
|
|
|
|
* (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 *
|
|
|
|
|
* by the Copyright Holder that are necessarily infringed by the Package. If *
|
|
|
|
|
* 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. *
|
|
|
|
|
* *
|
|
|
|
|
* (14) Disclaimer of Warranty: THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER *
