2. Basic Permissions.
All rights granted under this License are granted for the term of copyright on the Program, and are irrevocable provided the stated conditions are met. This
License explicitly affirms your unlimited permission to run the unmodified Program. The output from running a covered work is covered by this License only if the
output, given its content, constitutes a covered work. This License acknowledges your rights of fair use or other equivalent, as provided by copyright law.
You may make, run and propagate covered works that you do not convey, without conditions so long as your license otherwise remains in force. You may convey
covered works to others for the sole purpose of having them make modifications exclusively for you, or provide you with facilities for running those works, provided
that you comply with the terms of this License in conveying all material for which you do not control copyright. Those thus making or running the covered works for
you must do so exclusively on your behalf, under your direction and control, on terms that prohibit them from making any copies of your copyrighted material outside
their relationship with you. Conveying under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From anti-Circumvention Law.
No covered work shall be deemed part of an effective technological measure under any applicable law fulfilling obligations under article 11 of the WIPO copyright
treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumvention of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures to the extent such circumvention is effected by
exercising rights under this License with respect to the covered work, and you disclaim any intention to limit operation or modification of the work as a means of
enforcing, against the work's users, your or third parties' legal rights to forbid circumvention of technological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on
each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply
to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any
price or no price for each copy that you convey, and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
You may convey a work based on the Program, or the modifications to produce it from the Program, in the form of source code under the terms of section 4,
provided that you also meet all of these conditions:
a) The work must carry prominent notices stating that you modified it, and giving a relevant date.
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies
the requirement in section 4 to "keep intact all notices".
c) You must license the entire work, as a whole, under this License to anyone who comes into possession of a copy. This License will therefore apply, along
with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License gives no
permission to license the work in any other way, but it does not invalidate such permission if you have separately received it.
d) If the work has interactive user interfaces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not
display Appropriate Legal Notices, your work need not make them do so. A compilation of a covered work with other separate and independent works,
which are not by their nature extensions of the covered work, and which are not combined with it such as to form a larger program, in or on a volume of
a storage or distribution medium, is called an "aggregate" if the compilation and its resulting copyright are not used to limit the access or legal rights of
the compilation's users beyond what the individual works permit. Inclusion of a covered work in an aggregate does not cause this License to apply to the
other parts of the aggregate.
6. Conveying Non-Source Forms.
You may convey a covered work in object code form under the terms of sections 4 and 5, provided that you also convey the machine-readable Corresponding
Source under the terms of this License, in one of these ways:
a) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by the Corresponding Source
fixed on a durable physical medium customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least
three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code
either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily
used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the
Corresponding Source from a network server at no charge.
c) Convey individual copies of the object code with a copy of the written offer to provide the corresponding Source. This alternative is allowed only
occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b.
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer equivalent access to the Corresponding Source
in the same way through the same place at no further charge. You need not require recipients to copy the Corresponding Source along with the object
code. If the place to copy the object code is a network server, the Corresponding Source may be on a different server (operated by you or a third party)
that supports equivalent copying facilities, provided you maintain clear directions next to the object code saying where to find the Corresponding Source.
Regardless of what server hosts the Corresponding Source, you remain obligated to ensure that it is available for as long as needed to satisfy these
requirements.
e) Convey the object code using peer-to-peer transmission, provided you inform other peers where the object code and Corresponding Source of the
work are being offered to the general public at no charge under subsection 6d. A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be included in conveying the object code work. A "User Product" is either (1) a "consumer
product", which means any tangible personal property which is normally used for personal, family, or household purposes, or (2) anything designed or
sold for incorporation into a dwelling. In determining whether a product is a consumer product, doubtful cases shall be resolved in favor of coverage. For
a particular product received by a particular user, "normally used" refers to a typical or common use of that class of product, regardless of the status of
the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product
regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only significant mode of
use of the product.
"Installation Information" for a User Product means any methods, procedures, authorization keys, or other information required to install and execute modified
versions of a covered work in that User Product from a modified version of its Corresponding Source. The information must suffice to ensure that the continued
functioning of the modified object code is in no case prevented or interfered with solely because modification has been made. If you convey an object code
work under this section in, or with, or specifically for use in, a User Product, and the conveying occurs as part of a transaction in which the right of possession
and use of the User Product is transferred to the recipient in perpetuity or for a fixed term (regardless of how the transaction is characterized), the Corresponding
Source conveyed under this section must be accompanied by the Installation Information. But this requirement does not apply if neither you nor any third party
retains the ability to install modified object code on the User Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a requirement to continue to provide support service, warranty, or updates for a work that
has been modified or installed by the recipient, or for the User Product in which it has been modified or installed. Access to a network may be denied when
the modification itself materially and adversely affects the operation of the network or violates the 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 License by 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 License without 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 License with 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 License along with a term that is a further restriction, you may remove that term. If a license document
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 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 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 License (including any patent licenses granted 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 the copyright 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 ofthe violation
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 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, royaltyfree 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
