When you convey a copy of a covered work, you may at your option remove any additional permissions from that copy, orfrom any part of it. (Additional permissions may be written to require their own removal in certain cases when you modify thework.) You may place additional permissions on material, added by you to a covered work, for which you have or can giveappropriate copyright permission.Notwithstanding any other provision of this License, for material you add to a covered work, you may (if authorized by thecopyright holders of that material) supplement the terms of this License with terms:a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; orb) Requiring preservation of specified reasonable legal notices or author attributions in that material or in the AppropriateLegal Notices displayed by works containing it; orc) Prohibiting misrepresentation of the origin of that material, or requiring that modified versions of such material bemarked in reasonable ways as different from the original version; ord) Limiting the use for publicity purposes of names of licensors or authors of the material; ore) Declining to grant rights under trademark law for use of some trade names, trademarks, or service marks; orf) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or modifiedversions of it) with contractual assumptions of liability to the recipient, for any liability that these contractual assumptionsdirectly impose on those licensors and authors.All other non-permissive additional terms are considered “further restrictions” within the meaning of section 10. If the Programas you received it, or any part of it, contains a notice stating that it is governed by this License along with a term that is afurther restriction, you may remove that term. If a license document contains a further restriction but permits relicensing orconveying under this License, you may add to a covered work material governed by the terms of that license document,provided that the further restriction does not survive such relicensing or conveying.If you add terms to a covered work in accord with this section, you must place, in the relevant source files, a statement of theadditional terms that apply to those files, or a notice indicating where to find the applicable terms.Additional terms, permissive or non-permissive, may be stated in the form of a separately written license, or stated asexceptions; the above requirements apply either way.8. Termination.You may not propagate or modify a covered work except as expressly provided under this License. Any attempt otherwise topropagate or modify it is void, and will automatically terminate your rights under this License (including any patent licensesgranted under the third paragraph of section 11).However, if you cease all violation of this License, then your license from a particular copyright holder is reinstated (a)provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if thecopyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation.Moreover, your license from a particular copyright holder is reinstated permanently if the copyright holder notifies you of theviolation by some reasonable means, this is the first time you have received notice of violation of this License (for any work)from that copyright holder, and you cure the violation prior to 30 days after your receipt of the notice.Termination of your rights under this section does not terminate the licenses of parties who have received copies or rights fromyou under this License. If your rights have been terminated and not permanently reinstated, you do not qualify to receive newlicenses for the same material under section 10.9. Acceptance Not Required for Having Copies.You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propagation of a coveredwork occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not requireacceptance. However, nothing other than this License grants you permission to propagate or modify any covered work. Theseactions infringe copyright if you do not accept this License. Therefore, by modifying or propagating a covered work, youindicate your acceptance of this License to do so.10. Automatic Licensing of Downstream Recipients.Each time you convey a covered work, the recipient automatically receives a license from the original licensors, to run, modifyand propagate that work, subject to this License. You are not responsible for enforcing compliance by third parties with thisLicense.An “entity transaction” is a transaction transferring control of an organization, or substantially all assets of one, or subdividingan organization, or merging organizations. If propagation of a covered work results from an entity transaction, each partyto that transaction who receives a copy of the work also receives whatever licenses to the work the party’s predecessor ininterest had or could give under the previous paragraph, plus a right to possession of the Corresponding Source of the workfrom the predecessor in interest, if the predecessor has it or can get it with reasonable efforts.You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. For example,you may not impose a license fee, royalty, or other charge for exercise of rights granted under this License, and you may notinitiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is infringed by making,using, selling, offering for sale, or importing the Program or any portion of it.11. Patents.A “contributor” is a copyright holder who authorizes use under this License of the Program or a work on which the Program isbased. The work thus licensed is called the contributor’s “contributor version”.A contributor’s “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquiredor hereafter acquired, that would be infringed by some manner, permitted by this License, of making, using, or selling itscontributor version, but do not include claims that would be infringed only as a consequence of further modification of thecontributor version. For purposes of this definition, “control” includes the right to grant patent sublicenses in a mannerconsistent with the requirements of this License.––––––
