of this license document, but changing it is not allowed. |

Preamble |

"License" shall mean the terms and conditions for use, reproduction, |

The GNU General Public License is a free, copyleft license for |

"Licensor" shall mean the copyright owner or entity authorized by |

The licenses for most software and other practical works are designed |
the copyright owner that is granting the License. |

control with that entity. For the purposes of this definition, |

otherwise, or (ii) ownership of fifty percent (50%) or more of the |

When we speak of free software, we are referring to freedom, not |

"You" (or "Your") shall mean an individual or Legal Entity |

including but not limited to software source code, documentation |

source, and configuration files. |
||||||
To protect your rights, we need to prevent others from denying you |
|

these rights or asking you to surrender the rights. Therefore, you have |
"Object" form shall mean any form resulting from mechanical |

certain responsibilities if you distribute copies of the software, or if |

For example, if you distribute copies of such a program, whether |

gratis or for a fee, you must pass on to the recipients the same |

(an example is provided in the Appendix below). |

|
|

Developers that use the GNU GPL protect your rights with two steps: |
"Derivative Works" shall mean any work, whether in Source or Object |

For the developers' and authors' protection, the GPL clearly explains |
of this License, Derivative Works shall not include works that remain |
||||||
that there is no warranty for this free software. For both users' and |
separable from, or merely link (or bind by name) to the interfaces of, |

authors' sake, the GPL requires that modified versions be marked as |

|

authors of previous versions. |
"Contribution" shall mean any work of authorship, including |
||||||
|
the original version of the Work and any modifications or additions |
||||||
Some devices are designed to deny users access to install or run |
to that Work or Derivative Works thereof, that is intentionally |
||||||
modified versions of the software inside them, although the manufacturer |
submitted to Licensor for inclusion in the Work by the copyright owner |
||||||
can do so. This is fundamentally incompatible with the aim of |

to the Licensor or its representatives, including but not limited to |

|
designated in writing by the copyright owner as "Not a Contribution." |

Finally, every program is threatened constantly by software patents. |
|
||||||
States should not allow patents to restrict development and use of |
"Contributor" shall mean Licensor and any individual or Legal Entity |
||||||
software on general-purpose computers, but in those that do, we wish to |
on behalf of whom a Contribution has been received by Licensor and |

avoid the special danger that patents applied to a free program could |

make it effectively proprietary. To prevent this, the GPL assures that |
|

patents cannot be used to render the program non-free. |

APPENDIX: How to apply the Apache License to your work. |
||||||
3. Protecting Users' Legal Rights From Anti-Circumvention Law. |
|
||||||
|
To apply the Apache License to your work, attach the following |
||||||
No covered work shall be deemed part of an effective technological |
boilerplate notice, with the fields enclosed by brackets "[]" |
||||||
measure under any applicable law fulfilling obligations under article |
replaced with your own identifying information. (Don't include |
||||||
11 of the WIPO copyright treaty adopted on 20 December 1996, or |
the brackets!) The text should be enclosed in the appropriate |
||||||
similar laws prohibiting or restricting circumvention of such |
comment syntax for the file format. We also recommend that a |
||||||

||||||

same "printed page" as the copyright notice for easier |
||||||
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 |
Copyright [yyyy] [name of copyright owner] |
||||||
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 |
Licensed under the Apache License, Version 2.0 (the "License"); |
||||||
users, your or third parties' legal rights to forbid circumvention of |
you may not use this file except in compliance with the License. |
||||||
technological measures. |
You may obtain a copy of the License at |
||||||
|
|
||||||
4. Conveying Verbatim Copies. |
http://www.apache.org/licenses/LICENSE-2.0 |
||||||
|
|
||||||
You may convey verbatim copies of the Program's source code as you |
Unless required by applicable law or agreed to in writing, software |
||||||
receive it, in any medium, provided that you conspicuously and |
distributed under the License is distributed on an "AS IS" BASIS, |
||||||
appropriately publish on each copy an appropriate copyright notice; |
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. |
||||||
keep intact all notices stating that this License and any |
See the License for the specific language governing permissions and |
||||||
non-permissive terms added in accord with section 7 apply to the code; |
limitations under the License. |
||||||
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 of the |
|
||||||
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, 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. |
|
||||||
|
|
||||||
Nothing in this License shall be construed as excluding or limiting |
|
||||||
any implied license or other defenses to infringement that may |
|
||||||
otherwise be available to you under applicable patent law. |
|
||||||
|
|
||||||
12. No Surrender of Others' Freedom. |
|
||||||
|
|
||||||
If conditions are imposed on you (whether by court order, agreement or |
|
||||||
otherwise) that contradict the conditions of this License, they do not |
|
||||||
excuse you from the conditions of this License. If you cannot convey a |
|
||||||
covered work so as to satisfy simultaneously your obligations under this |
|
||||||
License and any other pertinent obligations, then as a consequence you may |
|
||||||
not convey it at all. For example, if you agree to terms that obligate you |
|
||||||
to collect a royalty for further conveying from those to whom you convey |
|
||||||
the Program, the only way you could satisfy both those terms and this |
|
||||||
License would be to refrain entirely from conveying the Program. |
|
||||||
|
|
||||||
13. Use with the GNU Affero General Public License. |
|
||||||
|
|
||||||
Notwithstanding any other provision of this License, you have |
|
||||||
permission to link or combine any covered work with a work licensed |
|
||||||
under version 3 of the GNU Affero General Public License into a single |
|
||||||
combined work, and to convey the resulting work. The terms of this |
|
||||||
License will continue to apply to the part which is the covered work, |
|
||||||
but the special requirements of the GNU Affero General Public License, |
|
||||||
section 13, concerning interaction through a network will apply to the |
|
||||||
combination as such. |
|
||||||
|
|
||||||
14. Revised Versions of this License. |
|
||||||
|
|
||||||
The Free Software Foundation may publish revised and/or new versions of |
|
||||||
the GNU General Public License from time to time. Such new versions will |
|
||||||
be similar in spirit to the present version, but may differ in detail to |
|
||||||
address new problems or concerns. |
|
||||||
|
|
||||||
Each version is given a distinguishing version number. If the |
|
||||||
Program specifies that a certain numbered version of the GNU General |
|
||||||
Public License "or any later version" applies to it, you have the |
|
||||||
option of following the terms and conditions either of that numbered |
|
||||||
version or of any later version published by the Free Software |
|
||||||
Foundation. If the Program does not specify a version number of the |
|
||||||
GNU General Public License, you may choose any version ever published |
|
||||||
by the Free Software Foundation. |
|
||||||
|
|
||||||
If the Program specifies that a proxy can decide which future |
|
||||||
versions of the GNU General Public License can be used, that proxy's |
|
||||||
public statement of acceptance of a version permanently authorizes you |
|
||||||
to choose that version for the Program. |
|
||||||
|
|
||||||
Later license versions may give you additional or different |
|
||||||
permissions. However, no additional obligations are imposed on any |
|
||||||
author or copyright holder as a result of your choosing to follow a |
|
||||||
later version. |
|
||||||
|
|
||||||
15. Disclaimer of Warranty. |
|
||||||
|
|
||||||
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY |
|
||||||
APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT |
|
||||||
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY |
|
||||||
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, |
|
||||||
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR |
|
||||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM |
|
||||||
IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF |
|
||||||
ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |
|
||||||
|
|
||||||
16. Limitation of Liability. |
|
||||||
|
|
||||||
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
|
||||||
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS |
|
||||||
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY |
|
||||||
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE |
|
||||||
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF |
|
||||||
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD |
|
||||||
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), |
|
||||||
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF |
|
||||||
SUCH DAMAGES. |
|
||||||
|
|
||||||
17. Interpretation of Sections 15 and 16. |
|
||||||
|
|
||||||
If the disclaimer of warranty and limitation of liability provided |
|
||||||
above cannot be given local legal effect according to their terms, |
|
||||||
reviewing courts shall apply local law that most closely approximates |
|
||||||
an absolute waiver of all civil liability in connection with the |
|
||||||
Program, unless a warranty or assumption of liability accompanies a |
|
||||||
copy of the Program in return for a fee. |
|
||||||
|
|
||||||
END OF TERMS AND CONDITIONS |
|
||||||
|
|
||||||
How to Apply These Terms to Your New Programs |
|
||||||
|
|
||||||
If you develop a new program, and you want it to be of the greatest |
|
||||||
possible use to the public, the best way to achieve this is to make it |
|
||||||
free software which everyone can redistribute and change under these terms. |
|
||||||
|
|
||||||
To do so, attach the following notices to the program. It is safest |
|
||||||
to attach them to the start of each source file to most effectively |
|
||||||
state the exclusion of warranty; and each file should have at least |
|
||||||
the "copyright" line and a pointer to where the full notice is found. |
|
||||||
|
|
||||||
<one line to give the program's name and a brief idea of what it does.> |
|
||||||
Copyright (C) <year> <name of author> |
|
||||||
|
|
||||||
This program is free software: you can redistribute it and/or modify |
|
||||||
it under the terms of the GNU General Public License as published by |
|
||||||
the Free Software Foundation, either version 3 of the License, or |
|
||||||
(at your option) any later version. |
|
||||||
|
|
||||||
This program is distributed in the hope that it will be useful, |
|
||||||
but WITHOUT ANY WARRANTY; without even the implied warranty of |
|
||||||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the |
|
||||||
GNU General Public License for more details. |
|
||||||
|
|
||||||
You should have received a copy of the GNU General Public License |
|
||||||
along with this program. If not, see <http://www.gnu.org/licenses/>. |
|
||||||
|
|
||||||
Also add information on how to contact you by electronic and paper mail. |
|
||||||
|
|
||||||
If the program does terminal interaction, make it output a short |
|
||||||
notice like this when it starts in an interactive mode: |
|
||||||
|
|
||||||
<program> Copyright (C) <year> <name of author> |
|
||||||
This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. |
|
||||||
This is free software, and you are welcome to redistribute it |
|
||||||
under certain conditions; type `show c' for details. |
|
||||||
|
|
||||||
The hypothetical commands `show w' and `show c' should show the appropriate |
|
||||||
parts of the General Public License. Of course, your program's commands |
|
||||||
might be different; for a GUI interface, you would use an "about box". |
|
||||||
|
|
||||||
You should also get your employer (if you work as a programmer) or school, |
|
||||||
if any, to sign a "copyright disclaimer" for the program, if necessary. |
|
||||||
For more information on this, and how to apply and follow the GNU GPL, see |
|
||||||
<http://www.gnu.org/licenses/>. |
|
||||||
|
|
||||||
The GNU General Public License does not permit incorporating your program |
|
||||||
into proprietary programs. If your program is a subroutine library, you |
|
||||||
may consider it more useful to permit linking proprietary applications with |
|
||||||
the library. If this is what you want to do, use the GNU Lesser General |
|
||||||
Public License instead of this License. But first, please read |
|
||||||
<http://www.gnu.org/philosophy/why-not-lgpl.html>. |
