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
