User Manual

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 License in 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 License grants 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 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, 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 license fee, 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 License of 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 license under
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 license to a party means to make such an agreement or commitment not to
enforce a patent against the party.
If you convey a covered work, knowingly relying on a patent license, and the
Corresponding Source of the work is not available for anyone to copy, free of charge and
under the terms of this License, through a publicly available network server or other readily
accessible means, then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the patent license for this
particular work, or (3) arrange, in a manner consistent with the requirements of this
License, to extend the patent license to downstream recipients. "Knowingly relying"
means you have actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work in a country, would
infringe one or more identifiable patents in that country that you have reason to believe are
valid.
If, pursuant to or in connection with a single transaction or arrangement, you convey, or
propagate by procuring conveyance of, a covered work, and grant a patent license to some
of the parties receiving the covered work authorizing them to use, propagate, modify or
convey a specific copy of the covered work, then the patent license you grant is
automatically extended to all recipients of the covered work and works based on it.
A patent license is "discriminatory" if it does not include within the scope of its coverage,
prohibits the exercise of, or is conditioned on the non-exercise of one or more of the rights
that are specifically granted under this License. You may not convey a covered work if
you are a party to an arrangement with a third party that is in the business of distributing
software, under which you make payment to the third party based on the extent of your
activity of conveying the work, and under which the third party grants, to any of the parties
who would receive the covered work from you, a discriminatory patent license (a) in
connection with copies of the covered work conveyed by you (or copies made from those
copies), or (b) primarily for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement, or that patent license
was granted, prior to 28 March 2007.
