GNU LESSER 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 allo wed.
This version of the GNU Lesser Gene ral Public License incorporates the terms and conditions of version 3 of the GNU General Public License, sup plemented by the additional
permissions listed below.
0. Additional Definitions.
As used herein, “this License” refers to v ersion 3 of the GNU Lesser Gene ral Public License, and the “GNU GPL” re fers to version 3 of the GN U 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 make s use of an interface provided by the Library, but which is not otherwise b ased on the Library. Defining a subclas s 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 parti cular version of the Library with whic h the Combined Work was made is
also called the “Linked Version”.
The “Minimal Corresponding Source” f or a Combined Work means the Correspo nding Source for the Combined W ork, 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” f or a Combined Work means the object code and/or source code for the Application, including any d ata 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 G NU GPL.
You may convey a covered work u nder 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 th e 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 App lication does not supply the function or da ta, 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 Licen se applicable to that copy.
3. Object Code Incorporating Material f rom Library Header Files.
The object code form of an Application may incorporate material from a he ader file that is part of the Library . You may convey such object code unde r terms of your choice,
provided that, if the incorporated material is not limited to numerical paramete rs, data structure layouts and acce ssors, or small macros, inline functions and templates (ten or
fewer lines in length), you do b oth 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 cop y of the GNU GPL and this license document.
4. Combined Works.
You may convey a Combined Work under terms of your choice that, take n together, effectively do not restrict modification of the portions of the Library contained in the
Combined Work and reverse eng ineering for debugging such modification s, 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 ex ecution, include the copyright notice for the Library among these notices, as well a s a reference directing the
user to the copies of the GNU GPL an d this license document.
d) Do one of the following:
0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Applicatio n 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 p roduce 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 mechani sm for linking with the Library. A suitable mechanism is one that (a) use s at run time a copy of the Library already
present on the user's computer system, a nd (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 und er section 6 of the G NU GPL, and only to the extent that such
information is necessary to install and execute a modified version of the Comb ined Work produced by recombining or relinking the App lication with a modified version of the
Linked Version. (If you use option 4d 0, the Installation Information mu st accompany the Minimal Corresponding Source and Corresponding A pplication Code. If you use option
4d1, you must provide the Installation Information in the manner specif ied 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 b y side in a single library togeth er with other library facilities that are not A pplications 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 und er the terms of this License.
b) Give prominent notice with the combine d library that part of it is a work based on the Library, and explaining where to find the accompany ing uncombined form of the same
work.
6. Revised Versions of the GNU Lesser G eneral Public License.
The Free Software Foundation may p ublish revised and/or new ve rsions of the GNU Lesser General Public License from time to time. Such new ve rsions will be similar in spirit
to the present version, but may d iffer in detail to address new problems or con cerns.
Each version is given a distinguishing v ersion number. If the Library as y ou 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 te rms and conditions either of that pub lished version or of any later ve rsion published by the Free Software
Foundation. If the Library as you receiv ed it does not specify a ve rsion number of the GNU Lesser General Pub lic License, you may choose any version of the GNU Lesser
General Public License ever pu blished by the Free Software Foundation.
I
f the Library as you received it specifies that a proxy can decide whether f uture 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 v ersion for the Library.

6. As an exception to the Sections abov e, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and
distribute that work under terms of your choice, provided that the terms p ermit modification of the work for the customer's own use and reve rse engineering for debugging
such modifications.
You must give prominent notice with eac h copy of the work that the Library is used in it and that the Library a nd its use are covered by th is License. You must supply a copy of
this License. If the work during e xecution displays copyright notices, you mu st include the copyright notice for the Library among them, as well a s a reference directing the user
to the copy of this License. Also, you must do one of these things:
a) Accompany the work with the comp lete corresponding machine-reada ble source code for the Library including whatever changes were used in the work (which must be
distributed under Sections 1 and 2 above); and, if the work is an exe cutable linked with the Library, with the complete machine-readable "work tha t uses the Library", as object
code and/or source code, so that the user can modify the Library and then relink to produce a modifie d executable containing the modified Library . (It is understood that the
user who changes the contents of d efinitions files in the Library will not ne cessarily be able to recompile the application to use the modified de finitions.)
b) Use a suitable shared library mechan ism for linking with the Library. A suitable mechanism is one that (1) use s at run time a copy of the library already present on the
user's computer system, rather than cop ying library functions into the ex ecutable, and (2) will operate prope rly with a modified version of the library, if the user installs one, as
long as the modified version is interfa ce-compatible with the version tha t the work was made with.
c) Accompany the work with a written offer, valid for at least three y ears, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the
cost of performing this distribution.
d) If distribution of the work is made by offering access to copy from a designated place, offer eq uivalent access to copy the above spe cified materials from the same place.
e) Verify that the user has alread y received a copy of these materials or that you have already sent this user a copy.
For an executable, the required form of the "work that uses the Library" mus t include any data and utility programs needed for reproducing the executable from it. However, as
a special exception, the materials to be distributed need not include any thing that is normally distributed (in e ither source or binary form) with the major components
(compiler, kernel, and so on) of the op erating system on which the e xecutable runs, unless that component it self accompanies the e xecutable.
It may happen that this requirement c ontradicts the license restrictions of othe r proprietary libraries that do not normally accompany the ope rating system. Such a contradiction means you cannot use both them and the Library together in an ex ecutable that you distribute.
7. You may place library facilities that are a work based on the Library sid e-by-side in a single library toge ther with other library facilities not covered by this License, and
distribute such a combined library, p rovided that the separate distribution of the work based on the Library and of the other library facilities is other wise permitted, and
provided that you do these two things:
a) Accompany the combined library with a copy of the same work ba sed on the Library, uncombined with any other library facilities. This must be distributed under the terms of
the Sections above.
b) Give prominent notice with the comb ined library of the fact that part of it is a work based on the Library, a nd explaining where to find the accompanying uncombined form of
the same work.
8. You may not copy, modify, sublicense , link with, or distribute the Library except as expressly prov ided under this License. Any attempt otherwise to copy, modify, sublicense,
link with, or distribute the Library is v oid, and will automatically terminate your rights under this License. Ho wever, parties who have re ceived copies, or rights, from you under
this License will not have their license s terminated so long as such parties rem ain in full compliance.
9. You are not required to accept this License, since you have not sign ed it. However, nothing else grants y ou permission to modify or d istribute the Library or its derivative
works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work b ased on the Library), you indicate
your acceptance of this License to do so, and all its terms and conditions f or copying, distributing or modifying the Library or works based on it.
10. Each time you redistribute the Libra ry (or any work based on the Library), the recipient automatically receive s a license from the original licen sor to copy, distribute, link
with or modify the Library subject to these terms and conditions. You may not impose any further restriction s on the recipients' exercise of the rights granted herein. You are
not responsible for enforcing compliance by third parties with this License.
11. If, as a consequence of a court judg ment or allegation of pa tent infringement or for any other re ason (not limited to patent issues), cond itions are imposed on you (whether
by court order, agreement or otherwi se) that contradict the conditions of th is License, they do not excuse you from the conditions of this License. If y ou cannot distribute so as
to satisfy simultaneously your obligatio ns under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example,
if a patent license would not permit roy alty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could
satisfy both it and this License would be to refrain entirely from distributi on of the Library.
If any portion of this section is held inv alid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is
intended to apply in other circumstan ces.
It is not the purpose of this section to induce you to infringe any pa tents or other property right claims or to conte st validity of any such claims; this section has the sole
purpose of protecting the integrity of the free software distribution system whi ch is implemented by public license practices. Many people have made generous contributions to
the wide range of software distribute d through that system in reliance on consistent application of that system; it is up to the author/donor to de cide if he or she is willing to
distribute software through any othe r system and a licensee cannot impose that choice.
This section is intended to make thorough ly clear what is believed to be a consequence of the rest of this License.
12. If the distribution and/or use of th e Library is restricted in certain count ries either by patents or by copyrighted interfaces, the original copyrig ht holder who places the
Library under this License may add an explicit geographical distribution li mitation excluding those countries, so that distribution is permitted only in or among countries not thus
excluded. In such case, this License inc orporates the limitation as if written in the body of this License.
13. The Free Software Foundation may publish revised and/or new v ersions of the Lesser General Public Li cense from time to time. Such new v ersions will be similar in spirit to
the present version, but may dif fer in detail to address new problems or con cerns.
Each version is given a distinguishing v ersion number. If the Library spe cifies a version number of this License whi ch applies to it and "any later version", you have the option of
following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version
number, you may choose any version e ver published by the Free Sof tware Foundation.
14. If you wish to incorporate parts of the Library into other free p rograms whose distribution conditions are inco mpatible with these, write to the author to ask for permission.
For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we s ometimes make exceptions for this. Ou r decision will be guided
by the two goals of preserving the free status of all derivatives of ou r free software and of promoting the sharing and reuse of software ge nerally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENS ED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY A PPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE C OPYRIGHT HOLDERS AN D/OR OTHER PARTIES PROVIDE THE LIBRAR Y "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, B UT NOT LIMITED TO, THE IMPLIED WARRA NTIES OF MERCHANTABILIT Y AND FITNESS FOR A PARTICULAR PUR POSE. THE ENTIRE RISK
AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SH OULD THE LIBRARY PROVE DEFECT IVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED B Y APPLICABLE LAW OR AGREE D TO IN WRITING WILL ANY COPYR IGHT HOLDER, OR ANY OTHER PART Y WHO MAY MODIFY AND/OR
REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUEN TIAL DAMAGES
ARISING OUT OF THE USE OR INABIL ITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
SUSTAINED BY YOU OR THIRD PAR TIES OR A FAILURE OF THE LIBRARY TO O PERATE WITH ANY OTHER SOFTWA RE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF S UCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your Ne w Libraries
If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that ev eryone can redistribute and change.
You can do so by permitting redistributi on under these terms (or, alternative ly, under the terms of the ordinary General Public License).
To apply these terms, attach the follo wing notices to the library. It is safest t o attach them to the start of each source file to most effectively conv ey 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 library's na me and an idea of what it does. Copyright (C) year name of author
This library is free software; you can redi stribute it and/or modify it under the terms of the GNU Lesser Gene ral Public License as published by the Free Software Foundation;
either version 2.1 of the License, or (a t your option) any later version.
This library is distributed in the hop e that it will be useful, but WITHOUT A NY WARRANTY; without even the imp lied warranty of MERCHANTAB ILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser G eneral Public License for more details.
You should have received a copy of the GNU Lesser General Public Licen se along with this library; if not, write to the Free Software Found ation, Inc., 51 Franklin Street, Fifth
Floor, Boston, MA 02110-1301 USA Also add information on how to contac t you by electronic and pape r mail. You should also get your employ er (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the lib rary, if necessary. Here is a sample; alte r the names:

Version 2.1, February 1999. Copyrigh t (C) 1991, 1999 Free Software Foundation, Inc., 51 Franklin Street, Fif th Floor, Boston, MA 02110-1301 US A
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allo wed.
[This is the first released version of the Lesser GPL. It also counts as the su ccessor of the GNU Library Public License, version 2, hence the version numb er 2.1.]
Preamble
The licenses for most software are d esigned to take away your freed om to share and change it. By contrast, the GNU General Public Licenses are inte nded to guarantee your
freedom to share and change fre e software--to make sure the software is fre e for all its users.
This license, the Lesser General Pub lic License, applies to some specially designated software packages--typ ically libraries--of the Free Software Foundation and other authors
who decide to use it. You can use it too , but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in
any particular case, based on the ex planations below.
When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are d esigned to make sure that y ou have the freedom to distribute
copies of free software (and charge for this service if you wish); that you re ceive source code or can get it if you want it; that you can change the software and use pieces of it
in new free programs; and that y ou are informed that you can do the se things.
To protect your rights, we need to make restrictions that forbid d istributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to
certain responsibilities for you if you distribute copies of the library or if you modify it.
For example, if you distribute copie s of the library, whether gratis or for a fee, you must give the recipie nts all the rights that we gave y ou. You must make sure that they, too,
receive or can get the source code. If y ou link other code with the library , you must provide complete object files to the recipients, so that they can relink them with the library
after making changes to the library and recompiling it. And you must show the m these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to cop y, distribute and/or
modify the library.
To protect each distributor, we want t o make it very clear that there is no warranty for the free library. A lso, if the library is modified by someone else and passed on, the
recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by prob lems that might be introduced by
others.
Finally, software patents pose a constant threat to the existence of an y free program. We wish to make sure tha t a company cannot effective ly restrict the users of a free
program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license ob tained for a version of the lib rary must be consistent with the full
freedom of use specified in this licen se.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This licen se, the GNU Lesser General Public License, applies to certain
designated libraries, and is quite d ifferent from the ordinary General Pub lic License. We use this license for certai n libraries in order to permit linking those libraries into nonfree programs.
When a program is linked with a library, whether statically or using a share d library, the combination of the two is legally speaking a combined work, a derivative of the original
library. The ordinary General Public Li cense therefore permits such linking only if the entire combination fits its cr iteria of freedom. The Lesser General Public License permits
more lax criteria for linking other cod e with the library.
We call this license the "Lesser" Ge neral Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free
software developers Less of an adv antage over competing non-free p rograms. These disadvantages are th e reason we use the ordinary Gene ral Public License for many
libraries. However, the Lesser license provides advantages in certain sp ecial circumstances.
For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-f acto standard. To achieve this,
non-free programs must be allowed to use the library. A more freque nt case is that a free library doe s the same job as widely used non-free libraries. In this case, there is little
to gain by limiting the free lib rary to free software only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to
use the GNU C Library in non-free p rograms enables many more peop le to use the whole GNU operating system, as well as its variant, the GN U/Linux operating system.
Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that th e user of a program that is linked with the Library has the freedom
and the wherewithal to run that program using a modified version of the Library .
The precise terms and conditions for c opying, distribution and modification follow. Pay close attention to the dif ference between a "work based on the library" and a "work that
uses the library". The former contain s code derived from the library, whereas the latter must be combined with the library in order to run.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applie s to any software library or other p rogram which contains a notice placed by the copyright holder or other authorized party saying it may be
distributed under the terms of this Les ser General Public License (also called "this License"). Each licensee is a ddressed as "you".
A "library" means a collection of software functions and/or data prep ared so as to be conveniently linke d with application programs (which use some of those functions and
data) to form executables.
The "Library", below, refers to any such software library or work which has bee n distributed under these terms. A "w ork based on the Library" means either the Library or any
derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or tran slated straightforwardly into
another language. (Hereinafter, translati on is included without limitation in the term "modification".)
"Source code" for a work means the pre ferred form of the work for making modifications to it. For a library, comp lete source code means all the sour ce code for all modules it
contains, plus any associated interfa ce definition files, plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not cov ered by this License; they are outside its scope. The act of running a program using the Library is not
restricted, and output from such a p rogram is covered only if its contents co nstitute a work based on the Library (independent of the use of the Library in a tool for writing it).
Whether that is true depends on what the Library does and what the program that uses the Library doe s.
1. You may copy and distribute v erbatim copies of the Library's complete source code as you receive it, in any medium, provided that y ou conspicuously and appropriately
publish on each copy an appropriate copyright notice and disclaimer of warran ty; keep intact all the notices that re fer to this License and to the ab sence of any warranty; and
distribute a copy of this License along with the Library.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty p rotection in exchange for a f ee.
2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Libra ry, and copy and distribute such modifications or work under
the terms of Section 1 above, prov ided that you also meet all of the se conditions:
a) The modified work must itself b e a software library.
b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change.
c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License.
d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application p rogram that uses the facility, other than as an argument passed
when the facility is invoked, then you must make a good faith effort to ensure that, in the event an ap plication does not supply such function or table , the facility still operates,
and performs whatever part of its p urpose remains meaningful.
(For example, a function in a library to compute square roots has a p urpose that is entirely well-defined independent of the application. Therefore , Subsection 2d requires that
any application-supplied function or table used by this function must be optional: if the application does not sup ply it, the square root function must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiab le sections of that work are not de rived from the Library, and can be reasonably considered independent
and separate works in themselves, then this License, and its terms, do not apply to those sections when y ou distribute them as separate work s. But when you distribute the
same sections as part of a whole which i s a work based on the Library, the distribution of the whole must b e on the terms of this License, who se permissions for other licensees
extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution
of derivative or collective works based on the Library.
In addition, mere aggregation of another work not based on the Library with the Library (or with a work base d on the Library) on a volume of a storage or distribution medium
does not bring the other work unde r the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public Licen se instead of this License to a given copy of the Library. To do this, you must alter all the notices
that refer to this License, so that they refer to the ordinary GNU Gene ral Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary
GNU General Public License has appeare d, then you can specify that v ersion instead if you wish.) Do not make any other change in these notices.
Once this change is made in a give n copy, it is irreversible for that copy, so the ordinary GNU General Public Li cense applies to all subsequent copie s and derivative works made
from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library.
4. You may copy and distribute th e Library (or a portion or derivative of it, under Section 2) in object code or e xecutable form under the terms of Sections 1 and 2 above
provided that you accompany it with the complete corresponding machine -readable source code, which mu st be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange.
If distribution of object code is made b y offering access to copy from a designated place, then offering e quivalent access to copy the source code from the same place satisfies
the requirement to distribute the sour ce code, even though third parties are not compelled to copy the source along with the object code.
5. A program that contains no derivativ e of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses
the Library". Such a work, in isolation, i s not a derivative work of the Library, and therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library creates an executable that is a derivativ e of the Library (because it contains portion s of the Library), rather
than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executab les.
When a "work that uses the Library" use s material from a header f ile that is part of the Library, the ob ject code for the work may be a derivative work of the Library eve n
though the source code is not. Wheth er this is true is especially signif icant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to
be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macr os and small inline functions
(ten lines or less in length), then the use of the object file is unrestricted, re gardless of whether it is legally a derivative work. (Executables conta ining this object code plus
portions of the Library will still fall und er Section 6.) Otherwise, if the work is a derivative of the Library, y ou may distribute the object code f or the work under the terms of
Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself.

12. No Surrender of Others' Freedom.
If conditions are imposed on you (whether by court order, agreement or othe rwise) that contradict the condition s of this License, they do not ex cuse you from the conditions of
this License. If you cannot convey a covered work so as to satisfy simultaneou sly your obligations under this License and any other pertinent ob ligations, then as a consequence
you may not convey it at all. For e xample, if you agree to terms that oblig ate 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 th e Program.
13. Use with the GNU Affero Gen eral Public License.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under ve rsion 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 c ontinue to apply to the p art which is the covered work, but the
special requirements of the GNU Af fero General Public License, section 13, co ncerning interaction through a ne twork will apply to the combination as such.
14. Revised Versions of this License.
The Free Software Foundation may p ublish revised and/or new ve rsions of the GNU General Public License from time to time. Such new ve rsions 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 v ersion number. If the Program spe cifies that a certain numbered ve rsion of the GNU General Public Licen se “or any later version” applies
to it, you have the option of f ollowing 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 numb er of the GNU General Public Licen se, you may choose any version ev er published by the Free Software Foundation.
If the Program specifies that a prox y 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 y ou additional or different permissions. Ho wever, no additional obligations are i mposed on any author or copyrigh t holder as a result of your
choosing to follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROG RAM, TO THE EXTENT PERM ITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WR ITING THE COPYRIGHT HOLDERS
AND/OR OTHER PARTIES PROVIDE THE P ROGRAM “AS IS” WITHOUT W ARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUD ING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES OF MERCHANTAB ILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMA NCE OF THE PROGRAM IS
WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASS UME THE COST OF ALL NECESSARY SERV ICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY A PPLICABLE LAW OR AGREED TO IN WR ITING WILL ANY COPYRIGHT H OLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES , INCLUDING ANY GENERAL, SPEC IAL, INCIDENTAL OR CONSEQUENTIA L DAMAGES ARISING OUT OF
THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMI TED TO LOSS OF DATA OR DATA B EING RENDERED INACCURATE OR LOSS ES SUSTAINED BY YOU
OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WI TH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PAR TY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitat ion of liability provided abov e cannot be given local legal effect according to their terms, reviewing courts shall apply local law that most
closely approximates an absolute waiv er 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 Ne w Programs
If you develop a new program, a nd 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 the se 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 progra m'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 GN U General Public License as published by
the Free Software Foundation, eithe r 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; with out even the implied warranty of
MERCHANTABILITY or FITNESS FO R A PARTICULAR PURPOSE. Se e the
GNU General Public License for mo re 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 contac t you by electronic and pa per mail.
If the program does terminal interact ion, make it output a short notice like this when it starts in an interactive mode:
<program> Copyright (C) <ye ar> <name of author>
This program comes with ABSOLU TELY NO WARRANTY; for details ty pe `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' an d `show c' should show the app ropriate parts of the General Pub lic License. Of course, your program's com mands might be different;
for a GUI interface, you would use an “ab out 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 m ore information on this,
and how to apply and follow the GNU GPL, see <
The GNU General Public License doe s not permit incorporating your p rogram into proprietary programs. If your p rogram is a subroutine library, you may consider it more useful
to permit linking proprietary application s with the library. If this is what y ou want to do, use the GNU Lesser General Public License instead of this License. But first, please read
<http://www.gnu.org/philosophy/why-n ot-lgpl.html>.

D I S P L A Y S L I M I T E D
d) Convey the object code by offering access from a designated place (gratis or for a charge), and offer e quivalent 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 cop y the object code is a
network server, the Corresponding Sour ce may be on a different se rver (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 Correspond ing 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 req uirements.
e) Convey the object code using p eer-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 cod e, whose source code is exclud ed from the Corresponding Source as a System Library, need not b e included in conveying the object code
work.
A “User Product” is either (1) a “consume r product”, which means any tangible personal property which is nor mally 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 prod uct, doubtful cases shall be resolve d in favor of coverage. For a
particular product received by a particular user, “normally used” refers to a typical or common use of that clas s of product, regardless of the status of the particular user or of
the way in which the particular user a ctually uses, or expects or is exp ected to use, the product. A product is a consumer product regardless of whe ther the product has
substantial commercial, industrial or no n-consumer uses, unless such u ses represent the only significant mod e of use of the product.
“Installation Information” for a User P roduct means any methods, procedures, authorization keys, or other infor mation required to install and ex ecute modified versions of a
covered work in that User Product f rom a modified version of its Correspond ing Source. The information must suffice to ensure that the continued functioning of the modified
object code is in no case prevente d or interfered with solely because modificatio n has been made.
If you convey an object code work und er this section in, or with, or specifica lly 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 p erpetuity or for a fixed term (regard less of how the transaction is charac terized), the Corresponding
Source conveyed under this section mu st be accompanied by the Installation Information. But this requirement does not apply if neither y ou 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 supp ort service, warranty, or upd ates for a work that has been
modified or installed by the recipie nt, or for the User Product in which it has been modified or installed. Acces s to a network may be d enied when the modification itself
materially and adversely affe cts the operation of the network or violate s the rules and protocols for communicat ion across the network.
Corresponding Source conveyed, and Installation Information provid ed, in accord with this section must b e in a format that is publicly documente d (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 sup plement 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 tre ated 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 pa rt may be used separately und er 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 tha t 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 permis sions 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 ad d 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 liab ility differently from the terms of sections 15 and 16 of this License; or
b) Requiring preservation of specif ied reasonable legal notices or author attributi ons in that material or in the Appropriate Legal Notices displayed by works containing it; or
c) Prohibiting misrepresentation of th e origin of that material, or requiring that modified versions of such mate rial be marked in reasonable ways as different from the original
version; or
d) Limiting the use for publicity purpose s of names of licensors or autho rs of the material; or
e) Declining to grant rights under trad emark law for use of some trade na mes, trademarks, or service marks; or
f) Requiring indemnification of licensors and authors of that material by anyone who conveys the material (or m odified versions of it) with contractual a ssumptions of liability to
the recipient, for any liability that these contractual assumptions directly impose on those licensors and autho rs.
All other non-permissive additional te rms are considered “further restri ctions” within the meaning of section 10. If the Program as you receiv ed it, or any part of it, contains a
notice stating that it is governed by this License along with a term tha t 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 b y the terms of that license document, p rovided that the further
restriction does not survive such relicens ing 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 tha t apply to those files, or a
notice indicating where to find the ap plicable terms.
Additional terms, permissive or non-perm issive, may be stated in the form of a separately written license, or stated as exceptions; the abov e requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as expressly p rovided under this License. Any attemp t otherwise to propagate or modif y it is void, and will automatically terminate your rights under this License (including any patent licenses g ranted under the third paragrap h of section 11).
However, if you cease all violation of this License, then your license from a p articular copyright holder is reinstated (a) provisionally, unless and until th e 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 pe rmanently if the copyright holder notif ies you of the violation by some re asonable means, this is the
first time you have received notice of violation of this License (for a ny work) from that copyright holder, and you cure the violation prior to 30 da ys after your receipt of the
notice.
Termination of your rights under this se ction does not terminate the licenses of parties who have received copies or rights from you unde r this License. If your rights have b een
terminated and not permanently reinstate d, you do not qualify to receive new licenses for the same material under section 10.
9. Acceptance Not Required for Hav ing Copies.
You are not required to accept this License in order to receive or run a copy of the Program. Ancillary propaga tion 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 th is License grants you p ermission to propagate or modify any
covered work. These actions infringe copyright if you do not accept this Li cense. Therefore, by modifying or propagating a covered work, y ou indicate your acceptance of this
License to do so.
10. Automatic Licensing of Downstream Re cipients.
Each time you convey a covered work, the recipient automatically receive s a license from the original licensors, to run, modify and prop agate that work, subject to this License.
You are not responsible for enforcing compliance by third parties with thi s License.
An “entity transaction” is a transaction tr ansferring control of an organization, or substantially all assets of one, or subdividing an organization, or merg ing organizations. If
propagation of a covered work re sults from an entity transaction, each p arty to that transaction who receive s a copy of the work also receive s whatever licenses to the work the
party's predecessor in interest had or co uld 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 ca n get it with reasonable ef forts.
You may not impose any further re strictions 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 gra nted under this License, and you may not initiate litigation (including a cross-claim or counterclaim in a lawsu it) alleging that any paten t
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 contr olled by the contributor, whether a lready acquired or hereaf ter acquired, that would be infringe d by
some manner, permitted by this License, of making, using, or selling its co ntributor version, but do not include claims that would be infringe d only as a consequence of furthe r
modification of the contributor version. For purposes of this definition, “cont rol” includes the right to grant pate nt sublicenses in a manner consistent w ith the requirements of
this License.
Each contributor grants you a non-exclu sive, worldwide, royalty-fre e patent license under the contributor's es sential patent claims, to mak e, use, sell, offer for sale, import and
otherwise run, modify and propa gate the contents of its contributor ve rsion.
In the following three paragraphs, a “patent license” is any expre ss agreement or commitment, however d enominated, not to enforce a patent (such as an express permission
to practice a patent or covenant not to sue for patent infringement). To “gran t” such a patent license to a party means to make such an agree ment or commitment not to
enforce a patent against the pa rty.
If you convey a covered work, k nowingly 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 Corre sponding Source to be so
available, or (2) arrange to dep rive yourself of the benefit of the pa tent license for this particular work, or (3) arran ge, in a manner consistent with the requirements of this
License, to extend the patent license to downstream recipients. “Knowingly relying” means you have actual k nowledge that, but for the p atent license, your conveying the
covered work in a country, or your recipie nt'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 sing le transaction or arrangement, you convey, or propagate b y procuring conveyance of, a covered work, and grant a patent license to
some of the parties receiving the cov ered work authorizing them to use, p ropagate, modify or convey a spe cific copy of the covered work, then the patent license you grant is
automatically extended to all re cipients of the covered work and works b ased on it.
A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exe rcise of, or is conditioned on the non-e xercise of one or more of the
rights that are specifically granted und er this License. You may not convey a covered work if you are a party to an arrangement with a third p arty that is in the business of
distributing software, under which you make payment to the third pa rty based on the extent of your activity of conveying the work, and und er which the third party grants, to
any of the parties who would receiv e the covered work from you, a discriminatory patent license (a) in connec tion with copies of the covered work conveyed by you (or copies
made from those copies), or (b) primarily for and in connection with specific prod ucts 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 construe d as excluding or limiting any implied license or other defenses to inf ringement that may otherwise be available to you under app licable
patent law.

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 allo wed.
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 designe d to take away your freedom to share and change the works. By contrast, the G NU General Public License
is intended to guarantee your f reedom 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 G eneral Public Licenses are desig ned to make sure that you hav e the freedom to distribute copies
of free software (and charge f or them if you wish), that you receive source code or can get it if you want it, that you can change the softwa re 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 y ou these rights or asking you to surrender the rights. Therefore, you have certain responsibilities if you
distribute copies of the software, or if y ou modify it: responsibilities to respect the freedom of others.
For example, if you distribute copie s of such a program, whether gratis or for a fee, you must pass on to the recipients the same freedoms that y ou received. You must make
sure that they, too, receive or can ge t the source code. And you must show the m these terms so they know their rights.
Developers that use the GNU GPL prote ct your rights with two steps: (1) as sert 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' p rotection, 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 cha nged, so that their problems will not be attributed erroneously to authors of p revious versions.
Some devices are designed to deny users access to install or run modified versions of the software inside them, alth ough 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 ab use occurs in the area of products f or individuals to use, which
is precisely where it is most unaccep table. Therefore, we have desig ned 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 f uture versions of the GPL, as nee ded to protect the freedom of users.
Finally, every program is threatened constantly by software patents. S tates should not allow patents to restr ict development and use of softwa re on general-purpose computers, but in those that do, we wish to avoid the special danger th at patents applied to a free prog ram could make it effectively proprietary . To prevent this, the GPL assures
that patents cannot be used to rend er the program non-free.
The precise terms and conditions for c opying, 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-lik e laws that apply to other kinds of works, such as semiconductor masks.
“The Program” refers to any copyrighta ble work licensed under this License. E ach licensee is addressed as “you ”. “Licensees” and “recipients ” may be individuals or organizations.
To “modify” a work means to copy f rom or adapt all or part of the work in a fashion requiring copyright pe rmission, 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 un modified Program or a work based on the Program.
To “propagate” a work means to do any thing with it that, without permis sion, would make you directly or secondarily liable for infringeme nt under applicable copyright law,
except executing it on a computer or modifying a private copy. Prop agation 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 k ind of propagation that enables other p arties to make or receive copies. Mere inte raction with a user through a comp uter network, with no
transfer of a copy, is not conveying.
An interactive user interface displays “Appropriate Legal Notices” to the e xtent that it includes a convenient and prominently visible feature that (1) displays an appropriate
copyright notice, and (2) tells the user tha t there is no warranty for the work (except to the extent that warranties are provided), that licensees may conve y the work under
this License, and how to view a copy of this License. If the interface presents a list of user commands or opti ons, such as a menu, a prominen t 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 interfa ce that either is an official standard defined by a recognized standards bod y, or, in the case of interfaces spe cified for a particular
programming language, one that is wide ly used among developers working in that language.
The “System Libraries” of an executab le work include anything, othe r than the work as a whole, that (a) is incl uded in the normal form of pa ckaging a Major Component, but
which is not part of that Major Compo nent, and (b) serves only to enab le use of the work with that Major Componen t, or to implement a Stand ard Interface for which an
implementation is available to the public in source code form. A “Major Co mponent”, in this context, means a major essential component (k ernel, 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 g enerate, 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 Librar ies, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but wh ich are not part of the work. For exa mple, Corresponding Source includes inte rface definition files
associated with source files for the work, and the source code for share d libraries and dynamically linked subprograms that the work is specifically designed to require, such as
by intimate data communication or contr ol flow between those subprograms and other parts of the work.
The Corresponding Source need not include anything that users can regen erate 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 p rovided the stated conditions are met. This License explicitly
affirms your unlimited permission to run the unmodified Program. The outp ut from running a covered work is covered by this License only if the output, given its content,
constitutes a covered work. This Licen se acknowledges your rights of fair use or other equivalent, as prov ided by copyright law.
You may make, run and propagate covered works that you do not conve y, without conditions so long as y our license otherwise remains in force. You may convey covered works
to others for the sole purpose of hav ing them make modifications exclusively for you, or provide you with f acilities for running those works, provide d that you comply with the
terms of this License in conveying all material for which you do not control copyright. Those thus making or run ning the covered works for y ou must do so exclusively on your
behalf, under your direction and control, on terms that prohibit them f rom making any copies of your copyrigh ted material outside their relation ship with you.
Conveying under any other circumstan ces is permitted solely unde r the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary.
3. Protecting Users' Legal Rights From A nti-Circumvention Law.
No covered work shall be dee med part of an effective technological measure under any applicable law f ulfilling obligations under article 11 of the WIPO copyright treaty adopted
on 20 December 1996, or similar law s prohibiting or restricting circumve ntion of such measures.
When you convey a covered work, you waive any legal power to forbid circumvention of technological measures t o the extent such circumvention is effected by exercising rights
under this License with respect to the cov ered work, and you disclaim any inte ntion to limit operation or modifica tion of the work as a means of e nforcing, against the work's
users, your or third parties' legal rig hts to forbid circumvention of te chnological measures.
4. Conveying Verbatim Copies.
You may convey verbatim copies of th e Program's source code as you receive it, in any medium, p rovided that you conspicuously and appropriate ly publish on each copy an
appropriate copyright notice; keep intact all notices stating that this Li cense and any non-permissive terms a dded in accord with section 7 ap ply 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, an d you may offer support or warranty prote ction for a fee.
5. Conveying Modified Source V ersions.
You may convey a work based on the Program, or the modifications to produ ce it from the Program, in the form of source code under the te rms of section 4, provided that you
also meet all of these conditions:
a) The work must carry prominent not ices stating that you modified it, a nd giving a relevant date.
b) The work must carry prominent noti ces 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 a pply, along with any applicable
section 7 additional terms, to the who le of the work, and all its parts, reg ardless of how they are package d. This License gives no permission to li cense the work in any other
way, but it does not invalidate such permission if you have separate ly received it.
d) If the work has interactive user interfa ces, each must display Appropriate Legal Notices; however, if the Program has interactive interfaces that do not display Appropriate
Legal Notices, your work need n ot make them do so.
A compilation of a covered work with othe r separate and independ ent 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 “aggre gate” if the compilation and its re sulting 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 aggreg ate 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 Corre sponding Source under the
terms of this License, in one of these wa ys:
a) Convey the object code in, or emb odied in, a physical product (including a physical distribution medium), a ccompanied by the Corresp onding Source fixed on a durable
physical medium customarily used f or software interchange.
b) Convey the object code in, or e mbodied in, a physical product (including a physical distribution medium), accompanied by a written off er, valid for at least three ye ars and
valid for as long as you offer spare parts or customer support for that p roduct model, to give anyone who p ossesses the object code either (1) a cop y of the Corresponding
Source for all the software in the prod uct that is covered by this License, on a durable physical medium customa rily used for software interchange, f or a price no more than
your reasonable cost of physically p erforming 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 off er, in accord with subsection 6b.
D I S P L A Y S L I M I T E D
12. IN NO EVENT UNLESS REQUIRED B Y APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYR IGHT HOLDER, OR ANY OTHER PA RTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YO U FOR DAMAGES, INCLUDING ANY G ENERAL, SPECIAL, INCIDENTAL O R CONSEQUENTIAL DAMAGES
ARISING OUT OF THE USE OR INABIL ITY TO USE THE PROGRAM (INCLU DING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES
SUSTAINED BY YOU OR THIRD PAR TIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGR AMS), EVEN IF SUCH HOLDE R OR OTHER PARTY HAS BEEN
ADVISED OF THE POSSIBILITY OF S UCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your Ne w Programs
If you develop a new program, a nd 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 the se 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 convey the exclusion of warranty; and each
file should have at least the "copy right" line and a pointer to where the full notice is found.
one line to give the program's na me and an idea of what it does.

This General Public License does not pe rmit incorporating your prog ram into proprietary programs. If you r program is a subroutine library, y ou may consider it more useful to
permit linking proprietary applications w ith the library. If this is what y ou want to do, use the
GNU Lesser General Public License instead of this License.

Version 2, June 1991, Copyright (C) 19 89, 1991 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, B oston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allo wed.
Preamble
The licenses for most software are d esigned to take away your freed om to share and change it. By contrast, the GNU General Public License is intend ed to guarantee your
freedom to share and change fre e software--to make sure the software is fre e for all its users. This General Public L icense applies to most of the Fre e Software Foundation's
software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License
instead.) You can apply it to your prog rams, too.
When we speak of free software, we are referring to freedom, not price. Our G eneral Public Licenses are desig ned to make sure that you hav e the freedom to distribute copies
of free software (and charge f or this service if you wish), that you receive source code or can get it if y ou 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 make restrictions that forbid any one to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain
responsibilities for you if you d istribute copies of the software, or if you modify it.
For example, if you distribute copie s of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have . You must make sure that they,
too, receive or can get the source code. And you must show them these terms s o they know their rights.
We protect your rights with two step s: (1) copyright the software, and (2) offer you this license which gives y ou legal permission to copy, distrib ute and/or modify the software.
Also, for each author's protection and our s, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by
someone else and passed on, we want its recipients to know that what they have is not the original, so that a ny problems introduced by others will n ot reflect on the original
authors' reputations.
Finally, any free program is threaten ed constantly by software pate nts. We wish to avoid the dange r that redistributors of a free program will in dividually obtain patent licenses,
in effect making the program p roprietary. To prevent this, we have made it clear that any patent must b e licensed for everyone's free use or not license d at all.
The precise terms and conditions for c opying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a not ice placed by the copyright hold er saying it may be distributed under the terms of this General Pub lic
License. The "Program", below, refers to any such program or work, and a "work based on the Program" means e ither the Program or any de rivative work under copyright law:
that is to say, a work containing the Program or a portion of it, either v erbatim or with modifications and/or tra nslated into another language. ( Hereinafter, translation is
included without limitation in the ter m "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not cov ered by this License; they are outside its scope. The act of running the Program is not restricted, and the
output from the Program is covered only if its contents constitute a work based on the Program (independ ent of having been made by runn ing the Program). Whether that is
true depends on what the Program does.
1. You may copy and distribute ve rbatim copies of the Program's source code as you receive it, in any me dium, provided that you conspicuou sly and appropriately publish on
each copy an appropriate copyrigh t notice and disclaimer of warranty; k eep intact all the notices that refer to th is License and to the absence of any warranty; and give any
other recipients of the Program a cop y of this License along with the Prog ram.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty p rotection in exchange for a f ee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and d istribute such modifications or work
under the terms of Section 1 above , provided that you also meet all of these conditions:
a) You must cause the modified file s to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that y ou distribute or publish, that in whole or in part contains or is derived f rom the Program or any part the reof, to be licensed as a whole at n o
charge to all third parties under the terms of this License.
c) If the modified program normally re ads commands interactively when run, you must cause it, when started runnin g for such interactive use in the most ordinary way, to
print or display an announcement inclu ding an appropriate copyright notice and a notice that there is no warran ty (or else, saying that you provide a warranty) and that users
may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Excep tion: if the Program itself is interactive but does not
normally print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiab le sections of that work are not de rived from the Program, and can be reasonably considered independent and separate works in themselve s, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the
same sections as part of a whole which i s a work based on the Progra m, the distribution of the whole must b e on the terms of this License, who se permissions for other
licensees extend to the entire whole, and thus to each and every p art regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution
of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution
medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, un der Section 2) in object code or executab le form under the terms of Sections 1 and 2 above provided tha t
you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which must be distributed u nder the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to g ive any third party, for a charge no more than your cost of physically perf orming source distribution, a
complete machine-readable copy of the corresponding source code , to be distributed under the terms of Sections 1 and 2 above on a med ium customarily used for software
interchange; or,
c) Accompany it with the information you received as to the offer to d istribute corresponding source code. (This alte rnative is allowed only f or noncommercial distribution and
only if you received the program in object code or executable form with such an offer, in accord with Subse ction b above.)
The source code for a work means the preferred form of the work for makin g modifications to it. For an executable work, complete source code me ans all the source code for all
modules it contains, plus any associated interface definition files, plus th e scripts used to control compilation and installation of the executab le. However, as a special exception,
the source code distributed need not include anything that is normally d istributed (in either source or binary form) with the major components (comp iler, kernel, and so on) of
the operating system on which the exe cutable runs, unless that component itself accompanies the executab le.
If distribution of executable or object code is made by offering access to copy from a designated place, the n offering equivalent access to copy the source code from the same
place counts as distribution of the sour ce code, even though third partie s are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicen se, or distribute the Program excep t as expressly provided und er this License. Any attempt otherwise to copy, modify, sublicense or
distribute the Program is void, and will a utomatically terminate your rig hts under this License. However, parties who have received copies, or rights, from you under this
License will not have their licenses ter minated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signe d it. However, nothing else grants y ou permission to modify or distribu te the Program or its derivative
works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work ba sed on the Program), you
indicate your acceptance of this License to do so, and all its terms and conditio ns for copying, distributing or modifying the Program or works based on it.
6. Each time you redistribute the Progra m (or any work based on the Program), the recipient automatically receiv es a license from the original li censor to copy, distribute or
modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights g ranted herein. You are not
responsible for enforcing compliance b y third parties to this License.
7. If, as a consequence of a court judg ment or allegation of patent inf ringement or for any other reason (not li mited to patent issues), conditions are imposed on you (whether
by court order, agreement or otherwi se) that contradict the conditions of th is License, they do not excuse you from the conditions of this License. If y ou cannot distribute so as
to satisfy simultaneously your obligatio ns under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example,
if a patent license would not permit roy alty-free redistribution of the Program by all those who receive copies d irectly or indirectly through you, th en the only way you could
satisfy both it and this License would be to refrain entirely from distributi on of the Program.
If any portion of this section is held inv alid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is
intended to apply in other circumstan ces.
It is not the purpose of this section to induce you to infringe any pa tents or other property right claims or to conte st validity of any such claims; this section has the sole
purpose of protecting the integrity of the free software distribution system, whi ch is implemented by public license practices. Many people have made generous contributions to
the wide range of software distribute d through that system in reliance on consistent application of that system; it is up to the author/donor to de cide if he or she is willing to
distribute software through any othe r system and a licensee cannot impose that choice.
This section is intended to make thorough ly clear what is believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain count ries either by patents or by copyrighted interfaces, the original cop yright holder who places the
Program under this License may add an explicit geographical distribution lim itation excluding those countries, so th at distribution is permitted only in or among countries not
thus excluded. In such case, this Licen se incorporates the limitation as if wri tten in the body of this License.
9. The Free Software Foundation may p ublish revised and/or new v ersions of the 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 v ersion number. If the Program spe cifies a version number of this Licen se which applies to it and "any later version", you have the option
of following the terms and conditions e ither of that version or of any later version published by the Free Software Foundation. If the Program d oes not specify a version number
of this License, you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free p rograms whose distribution conditions are dif ferent, write to the author to ask f or permission. For software
which is copyrighted by the Free Software Foundation, write to the Fre e Software Foundation; we sometimes mak e exceptions for this. Our decision wi ll be guided by the two
goals of preserving the free status of all derivatives of our free software and of promoting the sharing and re use of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSE D FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE C OPYRIGHT HOLDERS AN D/OR OTHER PARTIES PROVIDE THE PROGRA M "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, B UT NOT LIMITED TO, THE IMPLIED WARRA NTIES OF MERCHANTABILIT Y AND FITNESS FOR A PARTICULAR PUR POSE. THE ENTIRE RISK
AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS W ITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERV ICING, REPAIR OR CORRECTION.
