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
