|                     GNU GENERAL PUBLIC LICENSE
 | |
|                        Version 3, 29 June 2007
 | |
| 
 | |
|  Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
 | |
|  Everyone is permitted to copy and distribute verbatim copies
 | |
|  of this license document, but changing it is not allowed.
 | |
| 
 | |
|                             Preamble
 | |
| 
 | |
|   The GNU General Public License is a free, copyleft license for
 | |
| software and other kinds of works.
 | |
| 
 | |
|   The licenses for most software and other practical works are designed
 | |
| to take away your freedom to share and change the works.  By contrast,
 | |
| the GNU General Public License is intended to guarantee your freedom to
 | |
| share and change all versions of a program--to make sure it remains free
 | |
| software for all its users.  We, the Free Software Foundation, use the
 | |
| GNU General Public License for most of our software; it applies also to
 | |
| any other work released this way by its authors.  You can apply it to
 | |
| your programs, too.
 | |
| 
 | |
|   When we speak of free software, we are referring to freedom, not
 | |
| price.  Our General Public Licenses are designed to make sure that you
 | |
| have the freedom to distribute copies of free software (and charge for
 | |
| them if you wish), that you receive source code or can get it if you
 | |
| want it, that you can change the software or use pieces of it in new
 | |
| free programs, and that you know you can do these things.
 | |
| 
 | |
|   To protect your rights, we need to prevent others from denying you
 | |
| these rights or asking you to surrender the rights.  Therefore, you have
 | |
| certain responsibilities if you distribute copies of the software, or if
 | |
| you modify it: responsibilities to respect the freedom of others.
 | |
| 
 | |
|   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
 | |
| freedoms that you received.  You must make sure that they, too, receive
 | |
| or can get the source code.  And you must show them these terms so they
 | |
| know their rights.
 | |
| 
 | |
|   Developers that use the GNU GPL protect your rights with two steps:
 | |
| (1) assert copyright on the software, and (2) offer you this License
 | |
| giving you legal permission to copy, distribute and/or modify it.
 | |
| 
 | |
|   For the developers' and authors' protection, the GPL clearly explains
 | |
| that there is no warranty for this free software.  For both users' and
 | |
| authors' sake, the GPL requires that modified versions be marked as
 | |
| changed, so that their problems will not be attributed erroneously to
 | |
| authors of previous versions.
 | |
| 
 | |
|   Some devices are designed to deny users access to install or run
 | |
| modified versions of the software inside them, although the manufacturer
 | |
| can do so.  This is fundamentally incompatible with the aim of
 | |
| protecting users' freedom to change the software.  The systematic
 | |
| pattern of such abuse occurs in the area of products for individuals to
 | |
| use, which is precisely where it is most unacceptable.  Therefore, we
 | |
| have designed this version of the GPL to prohibit the practice for those
 | |
| products.  If such problems arise substantially in other domains, we
 | |
| stand ready to extend this provision to those domains in future versions
 | |
| of the GPL, as needed to protect the freedom of users.
 | |
| 
 | |
|   Finally, every program is threatened constantly by software patents.
 | |
| States should not allow patents to restrict development and use of
 | |
| software on general-purpose computers, but in those that do, we wish to
 | |
| 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.
 | |
| 
 | |
|   The precise terms and conditions for copying, distribution and
 | |
| modification follow.
 | |
| 
 | |
|                        TERMS AND CONDITIONS
 | |
| 
 | |
|   0. Definitions.
 | |
| 
 | |
|   "This License" refers to version 3 of the GNU General Public License.
 | |
| 
 | |
|   "Copyright" also means copyright-like laws that apply to other kinds of
 | |
| works, such as semiconductor masks.
 | |
| 
 | |
|   "The Program" refers to any copyrightable work licensed under this
 | |
| License.  Each licensee is addressed as "you".  "Licensees" and
 | |
| "recipients" may be individuals or organizations.
 | |
| 
 | |
|   To "modify" a work means to copy from or adapt all or part of the work
 | |
| in a fashion requiring copyright permission, other than the making of an
 | |
| exact copy.  The resulting work is called a "modified version" of the
 | |
| earlier work or a work "based on" the earlier work.
 | |
| 
 | |
|   A "covered work" means either the unmodified Program or a work based
 | |
| on the Program.
 | |
| 
 | |
|   To "propagate" a work means to do anything with it that, without
 | |
| permission, would make you directly or secondarily liable for
 | |
| infringement under applicable copyright law, except executing it on a
 | |
| computer or modifying a private copy.  Propagation includes copying,
 | |
| distribution (with or without modification), making available to the
 | |
| public, and in some countries other activities as well.
 | |
| 
 | |
|   To "convey" a work means any kind of propagation that enables other
 | |
| parties to make or receive copies.  Mere interaction with a user through
 | |
| a computer network, with no transfer of a copy, is not conveying.
 | |
| 
 | |
|   An interactive user interface displays "Appropriate Legal Notices"
 | |
| to the extent that it includes a convenient and prominently visible
 | |
| feature that (1) displays an appropriate copyright notice, and (2)
 | |
| tells the user that there is no warranty for the work (except to the
 | |
| extent that warranties are provided), that licensees may convey the
 | |
| work under this License, and how to view a copy of this License.  If
 | |
| the interface presents a list of user commands or options, such as a
 | |
| menu, a prominent item in the list meets this criterion.
 | |
| 
 | |
|   1. Source Code.
 | |
| 
 | |
|   The "source code" for a work means the preferred form of the work
 | |
| for making modifications to it.  "Object code" means any non-source
 | |
| form of a work.
 | |
| 
 | |
|   A "Standard Interface" means an interface that either is an official
 | |
| standard defined by a recognized standards body, or, in the case of
 | |
| interfaces specified for a particular programming language, one that
 | |
| is widely used among developers working in that language.
 | |
| 
 | |
|   The "System Libraries" of an executable work include anything, other
 | |
| than the work as a whole, that (a) is included in the normal form of
 | |
| packaging a Major Component, but which is not part of that Major
 | |
| Component, and (b) serves only to enable use of the work with that
 | |
| Major Component, or to implement a Standard Interface for which an
 | |
| implementation is available to the public in source code form.  A
 | |
| "Major Component", in this context, means a major essential component
 | |
| (kernel, window system, and so on) of the specific operating system
 | |
| (if any) on which the executable work runs, or a compiler used to
 | |
| produce the work, or an object code interpreter used to run it.
 | |
| 
 | |
|   The "Corresponding Source" for a work in object code form means all
 | |
| the source code needed to generate, install, and (for an executable
 | |
| work) run the object code and to modify the work, including scripts to
 | |
| control those activities.  However, it does not include the work's
 | |
| System Libraries, or general-purpose tools or generally available free
 | |
| programs which are used unmodified in performing those activities but
 | |
| which are not part of the work.  For example, Corresponding Source
 | |
| includes interface definition files associated with source files for
 | |
| the work, and the source code for shared libraries and dynamically
 | |
| linked subprograms that the work is specifically designed to require,
 | |
| such as by intimate data communication or control flow between those
 | |
| subprograms and other parts of the work.
 | |
| 
 | |
|   The Corresponding Source need not include anything that users
 | |
| can regenerate automatically from other parts of the Corresponding
 | |
| Source.
 | |
| 
 | |
|   The Corresponding Source for a work in source code form is that
 | |
| same work.
 | |
| 
 | |
|   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 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 <https://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.

 | |
| 
 | |
|   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
