License Compatibility. When you release a work based on the Program, you may include your own terms covering added parts for which you have, or can give, appropriate copyright permission, as long as those terms clearly permit all the activities that this License permits, or permit usage or relicensing under this License. Your terms may be written separately or may be this License plus additional written permission. If you so license your own added parts, those parts may be used separately under your terms, but the entire work remains under this License. Those who copy the work, or works based on it, must preserve your terms just as they must preserve this License, as long as any substantial portion of the parts they apply to are present. Aside from additional permissions, your terms may add limited kinds of additional requirements on your added parts, as follows: a) They may require the preservation of certain copyright notices, other legal notices, and/or author attributions, and may require that the origin of the parts they cover not be misrepresented, and/or that altered versions of them be marked in the source code, or marked there in specific reasonable ways, as different from the original version. b) They may state a disclaimer of warranty and liability in terms different from those used in this License. c) They may prohibit or limit the use for publicity purposes of specified names of contributors, and they may require that certain specified trademarks be used for publicity purposes only in the ways that are fair use under trademark law except with express permission. d) They may require that the work contain functioning facilities that allow users to immediately obtain copies of its Complete Corresponding Source Code. e) They may impose software patent retaliation, which means permission for use of your added parts terminates or may be terminated, wholly or partially, under stated conditions, for users closely related to any party that has filed a software patent lawsuit (i.e., a lawsuit alleging that some software infringes a patent). The conditions must limit retaliation to a subset of these two cases: 1. Lawsuits that lack the justification of retaliating against other software patent lawsuits that lack such justification. 2. Lawsuits that target part of this work, or other code that was elsewhere released together with the parts you added, the whole being under the terms used here for those parts. No other additional conditions are permitted in your terms; therefore, no other conditions can be present on any work that uses this License. This License does not attempt to enforce your terms, or assert that they are valid or enforceable by you; it simply does not prohibit you from employing them. When others modify the work, if they modify your parts of it, they may release such parts of their versions under this License without additional permissions, by including notice to that effect, or by deleting the notice that gives specific permissions in addition to this License. Then any broader permissions granted by your terms which are not granted by this License will not apply to their modifications, or to the modified versions of your parts resulting from their modifications. However, the specific requirements of your terms will still apply to whatever was derived from your added parts. Unless the work also permits distribution under a previous version of this License, all the other terms included in the work under this section must be listed, together, in a central list in the work.
