GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007

Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>

Everyone is permitted to copy and distribute verbatim copies of this license
document, but changing it is not allowed.

This version of the GNU Lesser General Public License incorporates the terms
and conditions of version 3 of the GNU General Public License, supplemented
by the additional permissions listed below.

0. Additional Definitions.

As used herein, "this License" refers to version 3 of the GNU Lesser General
Public License, and the "GNU GPL" refers to version 3 of the GNU General
Public License.

"The Library" refers to a covered work governed by this License, other than
an Application or a Combined Work as defined below.

An "Application" is any work that makes use of an interface provided by
the Library, but which is not otherwise based on the Library. Defining a
subclass of a class defined by the Library is deemed a mode of using an
interface provided by the Library.

A "Combined Work" is a work produced by combining or linking an Application
with the Library.  The particular version of the Library with which the
Combined Work was made is also called the "Linked Version".

The "Minimal Corresponding Source" for a Combined Work means the Corresponding
Source for the Combined Work, excluding any source code for portions of the
Combined Work that, considered in isolation, are based on the Application,
and not on the Linked Version.

The "Corresponding Application Code" for a Combined Work means the object
code and/or source code for the Application, including any data and utility
programs needed for reproducing the Combined Work from the Application,
but excluding the System Libraries of the Combined Work.

1. Exception to Section 3 of the GNU GPL.  You may convey a covered work
under sections 3 and 4 of this License without being bound by section 3 of
the GNU GPL.

2. Conveying Modified Versions.  If you modify a copy of the Library, and, in
your modifications, a facility refers to a function or data to be supplied by
an Application that uses the facility (other than as an argument passed when
the facility is invoked), then you may convey a copy of the modified version:

     a) under this License, provided that you make a good faith effort to
     ensure that, in the event an Application does not supply the function
     or data, the facility still operates, and performs whatever part of
     its purpose remains meaningful, or

     b) under the GNU GPL, with none of the additional permissions of this
     License applicable to that copy.

3. Object Code Incorporating Material from Library Header Files.  The object
code form of an Application may incorporate material from a header file
that is part of the Library.  You may convey such object code under terms of
your choice, provided that, if the incorporated material is not limited to
numerical parameters, data structure layouts and accessors, or small macros,
inline functions and templates (ten or fewer lines in length), you do both
of the following:

     a) Give prominent notice with each copy of the object code that the
     Library is used in it and that the Library and its use are covered by
     this License.

     b) Accompany the object code with a copy of the GNU GPL and this
     license document.

4. Combined Works.  You may convey a Combined Work under terms of your choice
that, taken together, effectively do not restrict modification of the portions
of the Library contained in the Combined Work and reverse engineering for
debugging such modifications, if you also do each of the following:

     a) Give prominent notice with each copy of the Combined Work that the
     Library is used in it and that the Library and its use are covered by
     this License.

     b) Accompany the Combined Work with a copy of the GNU GPL and this
     license document.

     c) For a Combined Work that displays copyright notices during execution,
     include the copyright notice for the Library among these notices, as
     well as a reference directing the user to the copies of the GNU GPL
     and this license document.

     d) Do one of the following:

           0) Convey the Minimal Corresponding Source under the terms of this
           License, and the Corresponding Application Code in a form suitable
           for, and under terms that permit, the user to recombine or relink
           the Application with a modified version of the Linked Version
           to produce a modified Combined Work, in the manner specified by
           section 6 of the GNU GPL for conveying Corresponding Source.

          1) Use a suitable shared library mechanism for linking with
          the Library.  A suitable mechanism is one that (a) uses at run
          time a copy of the Library already present on the user's computer
          system, and (b) will operate properly with a modified version of
          the Library that is interface-compatible with the Linked Version.

     e) Provide Installation Information, but only if you would otherwise
     be required to provide such information under section 6 of the GNU
     GPL, and only to the extent that such information is necessary to
     install and execute a modified version of the Combined Work produced
     by recombining or relinking the Application with a modified version
     of the Linked Version. (If you use option 4d0, the Installation
     Information must accompany the Minimal Corresponding Source and
     Corresponding Application Code. If you use option 4d1, you must provide
     the Installation Information in the manner specified by section 6 of
     the GNU GPL for conveying Corresponding Source.)

5. Combined Libraries.  You may place library facilities that are a work
based on the Library side by side in a single library together with other
library facilities that are not Applications and are not covered by this
License, and convey such a combined library under terms of your choice,
if you do both of the following:

     a) Accompany the combined library with a copy of the same work based
     on the Library, uncombined with any other library facilities, conveyed
     under the terms of this License.

     b) Give prominent notice with the combined library that part of it is a
     work based on the Library, and explaining where to find the accompanying
     uncombined form of the same work.

6. Revised Versions of the GNU Lesser General Public License.  The Free
Software Foundation may publish revised and/or new versions of the GNU Lesser
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 Library as
you received it specifies that a certain numbered version of the GNU Lesser
General Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that published version
or of any later version published by the Free Software Foundation. If the
Library as you received it does not specify a version number of the GNU
Lesser General Public License, you may choose any version of the GNU Lesser
General Public License ever published by the Free Software Foundation.

If the Library as you received it specifies that a proxy can decide whether
future versions of the GNU Lesser General Public License shall apply,
that proxy's public statement of acceptance of any version is permanent
authorization for you to choose that version for the Library.

GNU GENERAL PUBLIC LICENSE Version 3, 29 June 2007

Copyright © 2007 Free Software Foundation, Inc. <http://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 <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>.
