rules and protocols for communication across the network. Corresponding Source conveyed, and Installation Information
provided, in accord with this section must be in a format that is publicly documented (and with an implementation available to
the public in source code form), and must require no special password or key for unpacking, reading or copying. 7. Additional
Terms. "Additional permissions" are terms that supplement the terms of this licensesby making exceptions from one or more of
its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in
this License, to the extent that they are valid under applicable law. If additional permissions apply only to part of the Program,
that part may be used separately under those permissions, but the entire Program remains governed by this licenseswithout
regard to the additional permissions. When you convey a copy of a covered work, you may at your option remove any additional
permissions from that copy, or from any part of it. (Additional permissions may be written to require their own removal in certain
cases when you modify the work.) You may place additional permissions on material, added by you to a covered work, for which
you have or can give appropriate copyright permission. Notwithstanding any other provision of this License, for material you add
to a covered work, you may (if authorized by the copyright holders of that material) supplement the terms of this licenseswith
terms: a) Disclaiming warranty or limiting liability differently from the terms of sections 15 and 16 of this License; or b) Requiring
preservation of specified reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices
displayed by works containing it; or c) Prohibiting misrepresentation of the origin of that material, or requiring that modified
versions of such material be marked in reasonable ways as different from the original version; or d) Limiting the use for publicity
purposes of names of licensors or authors of the material; or e) Declining to grant rights under trademark law for use of some
trade names, trademarks, or service marks; or f) Requiring indemnification of licensors and authors of that material by anyone
who conveys the material (or modified versions of it) with contractual assumptions of liability to the recipient, for any liability
that these contractual assumptions directly impose on those licensors and authors. All other non-permissive additional terms are
considered "further restrictions" within the meaning of section 10. If the Program as you received it, or any part of it, contains a
notice stating that it is governed by this licensesalong with a term that is a further restriction, you may remove that term. If a
licensesdocument contains a further restriction but permits relicensing or conveying under this License, you may add to a
covered work material governed by the terms of that licensesdocument, 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 the additional 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 as
exceptions; 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 to propagate or modify it is void, and will automatically
terminate your rights under this licenses(including any patent licenses granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your licensesfrom a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and finally terminates your license, and (b) permanently, if the
copyright holder fails to notify you of the violation by some reasonable means prior to 60 days after the cessation. Moreover,
your licensesfrom a particular copyright holder is reinstated permanently if the copyright holder notifies you of the violation by
some reasonable means, this is the first time you have received notice of violation of this licenses(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 from you under this License. If your
rights have been terminated and not permanently reinstated, you do not qualify to receive new licenses for the same material
under section 10. 9. Acceptance Not Required for Having Copies. You are not required to accept this licensesin order to receive
or run a copy of the Program. Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer
transmission to receive a copy likewise does not require acceptance. However, nothing other than this licensesgrants you
permission to propagate or modify any covered work. These actions infringe copyright if you do not accept this License.
Therefore, by modifying or propagating a covered work, you indicate your acceptance of this licensesto do so. 10. Automatic
Licensing of Downstream Recipients. Each time you convey a covered work, the recipient automatically receives a licensesfrom
the original licensors, to run, modify and propagate that work, subject to this License. You are not responsible for enforcing
compliance by third parties with this License. An "entity transaction" is a transaction transferring control of an organization, or
substantially all assets of one, or subdividing an organization, or merging organizations. If propagation of a covered work results
from an entity transaction, each party to that transaction who receives a copy of the work also receives whatever licenses to
the work the party's predecessor in interest had or could give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from 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 licensesfee, royalty, or other charge for exercise of rights granted under this License, and you
may not initiate 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 licensesof the Program or a work on which the Program is based. 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 acquired or hereafter acquired, that would be infringed by some manner, permitted by this
License, of making, using, or selling its contributor version, but do not include claims that would be infringed only as a
consequence of further modification of the contributor version. For purposes of this definition, "control" includes the right to
grant patent sublicenses in a manner consistent with the requirements of this License. Each contributor grants you a non-
exclusive, worldwide, royalty-free patent licensesunder the contributor's essential patent claims, to make, use, sell, offer for
sale, import and otherwise run, modify and propagate the contents of its contributor version. In the following three paragraphs,
a "patent license" is any express agreement or commitment, however denominated, not to enforce a patent (such as an express
permission to practice a patent or covenant not to sue for patent infringement). To "grant" such a patent licensesto a party
means to make such an agreement or commitment not to enforce a patent against the party. If you convey a covered work,
