conditional and subject to Licensee's compliance with the following terms: 

(i) Licensee shall not remove or alter any copyright, trademark or other 
proprietary rights notice contained in any portion of the Licensed Software; 

(ii) Applications must add primary and substantial functionality to the 
Licensed Software; 

(iii) Applications may not pass on functionality which in any way makes it 
possible for others to create software with the Licensed Software; provided 
however that Licensee may use the Licensed Software's scripting and QML ("Qt 
Quick") functionality solely in order to enable scripting, themes and styles 
that augment the functionality and appearance of the Application(s) without 
adding primary and substantial functionality to the Application(s); 

(iv) Applications must not compete with the Licensed Software; 

(v) Licensee shall not use The Qt Company's or any of its suppliers' names, 
logos, or trademarks to market Applications, except that Licensee may use 
“Built with Qt” logo to indicate that Application(s) was developed using the 
Licensed Software; 

(vi) Licensee shall not distribute, sublicense or disclose source code of 
Licensed Software to any third party (provided however that Licensee may 
appoint employee(s) of Contractors as Designated Users to use Licensed 
Software pursuant to this Agreement). Such right may be available for the 
Licensee subject to a separate software development kit (“SDK”) license 
agreement to be concluded with The Qt Company; 

(vii) Licensee shall not grant the Customers a right to (i) make copies of the 
Redistributables except when and to the extent required to use the Applications 
and/or Devices for their intended purpose, (ii) modify the Redistributables or 
create derivative works thereof, (iii) decompile, disassemble or otherwise

the Redistributables to any third party, except as part of the onward sale of 
the Device on which the Redistributables are installed; 

(viii) Licensee shall not and shall cause that its Affiliates or Contractors 
shall not a) in any way combine, incorporate or integrate Licensed Software 
with, or use Licensed Software for creation of, any software created with or 
incorporating Open Source Qt, or b) incorporate or integrate Applications 
into a hardware device or product other than a Device, unless Licensee has 
received an advance written permission from The Qt Company to do so. Absent 
such written permission, any and all distribution by the Licensee during the 
Term of a hardware device or product a) which incorporate or integrate any 
part of Licensed Software or Open Source Qt; or b) where the main user 
interface or substantial functionality is provided by software build with 
Licensed Software or Open Source Qt or otherwise depends on the Licensed 
Software or Open Source Qt, shall be considered as a Device distribution under 
this Agreement and dependent on compliance thereof (including but not limited 
to obligation to pay applicable License Fees for such distribution); 

(ix) Licensee shall cause all of its Affiliates and Contractors entitled to 
make use of the licenses granted under this Agreement, to be contractually 
bound to comply with the relevant terms of this Agreement and not to use the 
Licensed Software beyond the terms hereof and for any purposes other than 
operating within the scope of their services for Licensee. Licensee shall be 
responsible for any and all actions and omissions of its Affiliates and 
Contractors relating to the Licensed Software and use thereof (including but 
not limited to payment of all applicable License Fees); 

(x) Except when and to the extent explicitly provided in this Section 3, 
Licensee shall not transfer, publish, disclose, display or otherwise make 
available the Licensed Software; 

; and 

(xi) Licensee shall not attempt or enlist a third party to conduct or attempt 
to conduct any of the above. 

Above terms shall not be applicable if and to the extent they conflict with any 
mandatory provisions of any applicable laws. 

Any use of Licensed Software beyond the provisions of this Agreement is 
strictly prohibited and requires an additional license from The Qt Company. 

4. THIRD PARTY SOFTWARE 

The Licensed Software may provide links to third party libraries or code 
(collectively "Third Party Software") to implement various functions. Third 
Party Software does not comprise part of the Licensed Software. In some cases, 
access to Third Party Software may be included in the Licensed Software. Such 
Third Party Software will be listed in the ".../src/3rdparty" source tree 
delivered with the Licensed Software or documented in the Licensed Software, as 
such may be amended from time to time. Licensee acknowledges that use or 
distribution of Third Party Software is in all respects subject to applicable 
license terms of applicable third party right holders. 

5. PRE-RELEASE CODE 

The Licensed Software may contain pre-release code and functionality marked or 
otherwise stated as “Technology Preview”, “Alpha”, “Beta” or similar 
designation. Such pre-release code may be present in order to provide 
experimental support for new platforms or preliminary versions of one or more 
new functionalities. The pre-release code may not be at the level of 
performance and compatibility of a final, generally available, product 
offering of the Licensed Software. The pre-release parts of the Licensed 
Software may not operate correctly, may contain errors and may be substantially 
modified by The Qt Company prior to the first commercial product release, if 
any. The Qt Company is under no obligation to make pre-release code 
commercially available, or provide any Support or Updates relating thereto. The 
Qt Company assumes no liability whatsoever regarding any pre-release code, but 
any use thereof is exclusively at Licensee’s own risk and expense. 

6. LIMITED WARRANTY AND WARRANTY DISCLAIMER 

The Qt Company hereby represents and warrants that it has the power and 
authority to grant the rights and licenses granted to Licensee under this 
Agreement. 

Except as set forth above, the Licensed Software is licensed to Licensee 
"as is" and Licensee’s exclusive remedy and The Qt Company’s entire liability 
for errors in the Licensed Software shall be limited, at The Qt Company’s 
option, to correction of the error, replacement of the Licensed Software or 
return of the applicable fees paid for the defective Licensed Software for the 
time period during which the License is not able to utilize the Licensed 
Software under the terms of this Agreement. 

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE QT COMPANY ON BEHALF OF 
ITSELF AND ITS LICENSORS, SUPPLIERS AND AFFILIATES, DISCLAIMS ALL OTHER 
WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED 
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON- 
INFRINGEMENT WITH REGARD TO THE LICENSED SOFTWARE. THE QT COMPANY DOES NOT 
WARRANT THAT THE LICENSED SOFTWARE WILL SATISFY LICENSEE’S REQUIREMENTS OR THAT 
IT WILL OPERATE WITHOUT DEFECT OR ERROR OR THAT THE OPERATION THEREOF WILL BE 
UNINTERRUPTED. ALL USE OF AND RELIANCE ON THE LICENSED SOFTWARE IS AT THE SOLE 
RISK OF AND RESPONSIBILITY OF LICENSEE. 

7. INDEMNIFICATION AND LIMITATION OF LIABILITY 

7.1 Limitation of Liability 

EXCEPT FOR (I) CASES OF GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT,  AND (II) 
BREACH OF CONFIDENTIALITY, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, IN NO 
EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY LOSS OF PROFIT, 
LOSS OF DATA, LOSS OF BUSINESS OR GOODWILL OR ANY OTHER INDIRECT, SPECIAL, 
CONSEQUENTIAL, INCIDENTAL OR PUNITIVE COST, DAMAGES OR EXPENSE OF ANY KIND, 
HOWSOEVER ARISING UNDER OR IN CONNECTION WITH THIS AGREEMENT. PARTIES 
SPECIFICALLY AGREE THAT LICENSEE’S OBLIGATION TO PAY LICENSE AND OTHER FEES 
CORRESPONDING TO ACTUAL USAGE OF LICENSED SOFTWARE HEREUNDER SHALL BE 
CONSIDERED AS A DIRECT DAMAGE. 

EXCEPT FOR (I) CASES OF GROSS NEGLIGENCE OR INTENTIONAL MISCONDUCT,  AND (II) 
BREACH OF CONFIDENTIALITY, AND TO THE EXTENT PERMITTED BY APPLICABLE LAW, IN 
NO EVENT SHALL EITHER PARTY’S TOTAL AGGREGATE LIABILITY UNDER THIS AGREEMENT 
EXCEED THE AGGREGATE LICENSE FEES PAID OR PAYABLE TO THE QT COMPANY FROM 
LICENSEE DURING THE PERIOD OF TWELVE (12) MONTHS IMMEDIATELY PRECEDING THE 
EVENT RESULTING IN SUCH LIABILITY. 

THE PROVISIONS OF THIS SECTION 7 ALLOCATE THE RISKS UNDER THIS AGREEMENT 
BETWEEN THE QT COMPANY AND LICENSEE AND THE PARTIES HAVE RELIED UPON THE 
LIMITATIONS SET FORTH HEREIN IN DETERMINING WHETHER TO ENTER INTO THIS AGREEMENT. 

7.2 Licensee´s Indemnification 

Licensee shall indemnify and hold harmless The Qt Company from and against any 
claim, injury, judgment, settlement, loss or expense, including attorneys' fees 
related to: (a) Licensee’s misrepresentation in connection with The Qt Company 
or the Licensed Software or breach of this Agreement, (b) the Application or 
Device (except where such cause of liability is solely attributable to the 
Licensed Software). 

8. SUPPORT, UPDATES AND ONLINE SERVICES 

Upon due payment of the agreed License Fees the Licensee will be eligible to 
receive Support and Updates and to use the Online Services during the License 
Term, provided, however, that in the event the License Term is longer than 36 
months, Support is provided only for the first 12 months, unless the Parties 
specifically otherwise agree. 

Unless otherwise decided by The Company at its free and absolute discretion, 
Upgrades will not be included in the Support but may be available subject to 
additional fees. 

From time to time The Qt Company may change the Support terms, provided that 
during the respective ongoing License Term the level of Support provided by The 
Qt Company may not be reduced without the consent of the Licensee. 

Unless otherwise agreed, The Qt Company shall not be responsible for providing 
any service or support to Customers. 

9. CONFIDENTIALITY 

Each Party acknowledges that during the Term of this Agreement each Party may 
receive information about the other Party's business, business methods, 
business plans, customers, business relations, technology, and other 
information, including the terms of this Agreement, that is confidential and 
of great value to the other Party, and the value of which would be 
significantly reduced if disclosed to third parties (“Confidential 
Information”). Accordingly, when a Party (the “Receiving Party”) receives 
Confidential Information from the other Party (the “Disclosing Party”), the 
Receiving Party shall only disclose such information to employees and 
Contractors on a need to know basis, and shall cause its employees and 
employees of its Affiliates to: (i) maintain any and all Confidential 
Information in confidence; (ii) not disclose the Confidential Information to a 
third party without the Disclosing Party's prior written approval; and (iii) 
not, directly or indirectly, use the Confidential Information for any purpose 
other than for exercising its rights and fulfilling its responsibilities 
pursuant to this Agreement. Each Party shall take reasonable measures to 
protect the Confidential Information of the other Party, which measures shall 
not be less than the measures taken by such Party to protect its own 
confidential and proprietary information. 

Obligation of confidentiality shall not apply to information that (i) is or 
becomes generally known to the public through no act or omission of the 
Receiving Party; (ii) was in the Receiving Party's lawful possession prior to 
the disclosure hereunder and was not subject to limitations on disclosure or 
use; (iii) is developed independently by employees or Contractors of the 
Receiving Party or other persons working for the Receiving Party who have not 
had access to the Confidential Information of the Disclosing Party, as proven 
by the written records of the Receiving Party; (iv) is lawfully disclosed to 
the Receiving Party without restrictions, by a third party not under an 
obligation of confidentiality; or (v) the Receiving Party is legally compelled 
to disclose, in which case the Receiving Party shall notify the Disclosing 
Party of such compelled disclosure and assert the privileged and confidential 
nature of the information and cooperate fully with the Disclosing Party to 
limit the scope of disclosure and the dissemination of disclosed Confidential 
Information to the minimum extent necessary. 

The obligations under this Section 9 shall continue to remain in force for a 
period of five (5) years after the last disclosure, and, with respect to trade 
secrets, for so long as such trade secrets are protected under applicable trade 
secret laws. 

10. FEES, DELIVERY AND PAYMENT 

10.1 License Fees 

License Fees are described in The Qt Company’s standard price list, quote or 
Purchase Order confirmation or in an appendix hereto, as the case may be. 

The License Fees shall not be refunded or claimed as a credit in any event or 
for any reason whatsoever. 

10.2 Ordering Licenses 

Licensee may purchase Development Licenses and Distribution Licenses pursuant 
to agreed pricing terms or, if no specific pricing terms have been agreed upon, 
at The Qt Company's standard pricing terms applicable at the time of purchase. 

Licensee shall submit all purchase orders for Development Licenses and 
Distribution Licenses to The Qt Company by email or any other method acceptable 
to The Qt Company (each such order is referred to herein as a “Purchase Order”) 
for confirmation, whereupon the Purchase Order shall become binding between the 
Parties. 

10.3 Distribution License Packs 

Unless otherwise agreed, Distribution Licenses shall be purchased by way of 
Distribution License Packs. 

Upon due payment of the ordered Distribution License Pack(s), the Licensee will 
have an account of Distribution Licenses available for installing, bundling or 
integrating (all jointly “installing”) the Redistributables with the Devices or 
for otherwise distributing the Redistributables in accordance with this 
Agreement. 

Each time Licensee “installs” or distributes a copy of Redistributables, then 
one Distribution License is used, and Licensee’s account of available 
Distribution Licenses is decreased accordingly. 

Licensee may “install” copies of the Redistributables so long as Licensee has 
Distribution Licenses remaining on its account. 

Redistributables will be deemed to have been “installed” into a Device when one 
of the following circumstances shall have occurred: a) the Redistributables 
have been loaded onto the Device and used outside of the Licensee’s premises or 
b) the Device has been fully tested and placed into Licensee's inventory 
(or sold) for the first time (i.e., Licensee will not be required to use 
(or pay for) more than one Distribution License for each individual Device, 
e.g. in a situation where a Device is returned to Licensee's inventory after 
delivery to a distributor or sale to a Customer). In addition, if Licensee 
includes a back-up copy of the Redistributables on a CD-ROM or other storage 
medium along with the product, that backup copy of the Redistributables will 
not be deemed to have been “installed” and will not require an additional 
Distribution License. 

10.4 Payment Terms 

License Fees and any other charges under this Agreement shall be paid by 
Licensee no later than thirty (30) days from the date of the applicable invoice 
from The Qt Company. 

The Qt Company will submit an invoice to Licensee after the date of this 
Agreement and/or after The Qt Company receives a Purchase Order from 
Licensee. 

A late payment charge of the lower of (a) one percent per month; or (b) the 
interest rate stipulated by applicable law, shall be charged on any unpaid 
balances that remain past due. 

The Qt Company shall have the right to suspend, terminate or withhold grants 
of all rights to the Licensed Software hereunder, including but not limited to 
the Developer License, Distribution License, and Support, should Licensee fail 
to make payment in timely fashion. 

10.5 Taxes 

All License Fees and other charges payable hereunder are gross amounts but 
exclusive of any value added tax, use tax, sales tax and other taxes, duties or 
tariffs (“Taxes”). Such applicable Taxes shall be paid by Licensee, or, where 
applicable, in lieu of payment of such Taxes, Licensee shall provide an 
exemption certificate to The Qt Company and any applicable authority. 

11 RECORD-KEEPING AND REPORTING OBLIGATIONS; AUDIT RIGHTS 

11.1 Licensee’s Record-keeping 

Licensee shall at all times maintain accurate and up-to-date written records of 
Licensee’s activities related to the use of Licensed Software and distribution 
of Redistributables. The records shall be adequate to determine Licensee’s 
compliance with the provisions of this Agreement and to demonstrate the number 
of Designated Users and Redistributables distributed by Licensee. The records 
shall conform to good accounting practices reasonably acceptable to The Qt 
Company. 

Licensee shall, within thirty (30) days from receiving The Qt Company’s request 
to that effect, deliver to The Qt Company a report on Licensee’s usage of 
Licensed Software, such report to copies of Redistributables distributed by 
Licensee during that calendar quarter, and also detailing the number of 
undistributed copies of Redistributables made by Licensee and remaining in its 
account contain information, in sufficient detail, on (i) amount of users 
working with Licensed Software, (ii) copies of Redistributables distributed by 
Licensee during that calendar quarter, (iii) number of undistributed copies of 
Redistributables and corresponding number of unused Distribution Licenses 
remaining on Licensee’s account, and (iv) any other information as The Qt 
Company may reasonably require from time to time. 

11.2. The Qt Company’s Audit Rights 

The Qt Company or an independent auditor acting on behalf of The Qt Company’s, 
may, upon at least five (5) business days’ prior written notice and at its 
expense, audit Licensee with respect to the use of the Redistributables, but 
not more frequently than once during each 6-month period. Such audit may be 
conducted by mail, electronic means or through an in-person visit to Licensee’s 
place of business. Any such in-person audit shall be conducted during regular 
business hours at Licensee's facilities and shall not unreasonably interfere 
with Licensee's business activities. The Qt Company or the independent auditor 
acting on behalf of The Qt Company shall be entitled to inspect Licensee’s 
Records. All such Licensee’s Records and use thereof shall be subject to an 
obligation of confidentiality under this Agreement. 

If an audit reveals that Licensee is using the Licensed Software beyond scope 
of the licenses Licensee has paid for, Licensee agrees to immediately pay The 
Qt Company any amounts owed for such unauthorized use. 

In addition, in the event the audit reveals a material violation of the terms 
of this Agreement (underpayment of more than 5% of License Fees shall always be 
deemed a material violation for purposes of this section), then the Licensee 
shall pay The Qt Company's reasonable cost of conducting such audit. 

12 TERM AND TERMINATION 

12.1 Term 

This Agreement shall enter into force upon due acceptance by both Parties and 
remain in force for as long as there is any Development License(s) in force 
(“Term”), unless and until terminated pursuant to the terms of this Section 12. 

12.2 Termination by The Qt Company 

The Qt Company shall have the right to terminate this Agreement upon thirty 
(30) days prior written notice if the Licensee is in material breach of any 
obligation of this Agreement and fails to remedy such breach within such notice 
period. 

12.3 Mutual Right to Terminate 

Either Party shall have the right to terminate this Agreement immediately upon

substantial part of its assets, ceases to conduct business, or an act 
equivalent to any of the above occurs under the laws of the jurisdiction of the 
other Party. 

12.4 Parties´ Rights and Duties upon Termination 

Upon expiry or termination of the Agreement Licensee shall cease and shall 
cause all Designated Users (including those of its Affiliates’ and 
Contractors’) to cease using the Licensed Software and distribution of the 
Redistributables under this Agreement. 

Notwithstanding the above, in the event the Agreement expires or is terminated: 

(i) as a result of The Qt Company choosing not to renew the Development 
License(s) as set forth in Section 3.1, then all valid licenses possessed by 
the Licensee at such date shall be extended to be valid in perpetuity under the 
terms of this Agreement and Licensee is entitled to purchase additional 
licenses as set forth in Section 10.2; or 

(ii) for reason other than by The Qt Company pursuant to item (i) above or 
pursuant to Section 12.2, then the Licensee is entitled, for a period of six 
(6) months after the effective date of termination, to continue distribution of 
Devices under the Distribution Licenses paid but unused at such effective date 
of termination. 

Upon any such termination the Licensee shall destroy or return to The Qt 
Company all copies of the Licensed Software and all related materials and will 
certify the same to The Qt Company upon its request, provided however that 
Licensee may retain and exploit such copies of the Licensed Software as it may 
reasonably require in providing continued support to Customers. 

Expiry or termination of this Agreement for any reason whatsoever shall not 
relieve Licensee of its obligation to pay any License Fees accrued or payable 
to The Qt Company prior to the effective date of termination, and Licensee 
shall immediately pay to The Qt Company all such fees upon the effective date 
of termination.  Termination of this Agreement shall not affect any rights of 
Customers to continue use of Applications and Devices (and therein incorporated 
Redistributables). 

12.5 Extension in case of bankruptcy 

In the event The Qt Company is declared bankrupt under a final, non-cancellable 
decision by relevant court of law, and this Agreement is not, at the date of 
expiry of the Development License(s) pursuant to Section 3.1, assigned to 
party, who has assumed The Qt Company’s position as a legitimate licensor of 
Licensed Software under this Agreement, then all valid licenses possessed by 
the Licensee at such date of expiry, and which the Licensee has not notified 
for expiry, shall be extended to be valid in perpetuity under the terms of 
this Agreement. 

13. GOVERNING LAW AND LEGAL VENUE

or if either Party so requires, of three (3), arbitrators. The award shall be 
final and binding and enforceable in any court of competent jurisdiction. The 
arbitration shall be held in Helsinki, Finland and the process shall be 
conducted in the English language. This Section shall not preclude parties from 
seeking provisional remedies in aid of arbitration from a court of appropriate 
jurisdiction. 

14. GENERAL PROVISIONS

The Qt Company shall be entitled to freely assign or transfer any of its 
rights, benefits or obligations under this Agreement.

Any terms and conditions that by their nature or otherwise reasonably should 
survive termination of this Agreement shall so be deemed to survive. 

14.4 Entire Agreement 

This Agreement, the exhibits hereto, the License Certificate and any applicable 
Purchase Order constitute the complete agreement between the Parties and 
supersedes all prior or contemporaneous discussions, representations, and 
proposals, written or oral, with respect to the subject matters discussed

14.6 Force Majeure 

Except for the payment obligations hereunder, neither Party shall be liable to

of act of God, terrorist attack or other similar unforeseeable catastrophic 
event that prevents either Party for fulfilling its obligations under this 
Agreement and which such Party cannot avoid or circumvent (“Force Majeure 
Event”).  If the Force Majeure Event results in a delay or non-performance of a 
Party for a period of three (3) months or longer, then either Party shall have 
the right to terminate this Agreement with immediate effect without any 
liability (except for the obligations of payment arising prior to the event of 
Force Majeure) towards the other Party.

Copyright (C) 2000, 2001, 2002, 2007, 2008 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. 

0. PREAMBLE 

The purpose of this License is to make a manual, textbook, or other 
functional and useful document "free" in the sense of freedom: to 
assure everyone the effective freedom to copy and redistribute it, 
with or without modifying it, either commercially or noncommercially. 
Secondarily, this License preserves for the author and publisher a way 
to get credit for their work, while not being considered responsible 
for modifications made by others. 

This License is a kind of "copyleft", which means that derivative 
works of the document must themselves be free in the same sense.  It 
complements the GNU General Public License, which is a copyleft 
license designed for free software. 

We have designed this License in order to use it for manuals for free 
software, because free software needs free documentation: a free 
program should come with manuals providing the same freedoms that the 
software does.  But this License is not limited to software manuals; 
it can be used for any textual work, regardless of subject matter or 
whether it is published as a printed book.  We recommend this License 
principally for works whose purpose is instruction or reference. 


1. APPLICABILITY AND DEFINITIONS 

This License applies to any manual or other work, in any medium, that 
contains a notice placed by the copyright holder saying it can be 
distributed under the terms of this License.  Such a notice grants a 
world-wide, royalty-free license, unlimited in duration, to use that 
work under the conditions stated herein.  The "Document", below, 
refers to any such manual or work.  Any member of the public is a 
licensee, and is addressed as "you".  You accept the license if you 
copy, modify or distribute the work in a way requiring permission 
under copyright law. 

A "Modified Version" of the Document means any work containing the 
Document or a portion of it, either copied verbatim, or with 
modifications and/or translated into another language. 

A "Secondary Section" is a named appendix or a front-matter section of 
the Document that deals exclusively with the relationship of the 
publishers or authors of the Document to the Document's overall 
subject (or to related matters) and contains nothing that could fall 
directly within that overall subject.  (Thus, if the Document is in 
part a textbook of mathematics, a Secondary Section may not explain 
any mathematics.)  The relationship could be a matter of historical 
connection with the subject or with related matters, or of legal, 
commercial, philosophical, ethical or political position regarding 
them. 

The "Invariant Sections" are certain Secondary Sections whose titles 
are designated, as being those of Invariant Sections, in the notice 
that says that the Document is released under this License.  If a 
section does not fit the above definition of Secondary then it is not 
allowed to be designated as Invariant.  The Document may contain zero 
Invariant Sections.  If the Document does not identify any Invariant 
Sections then there are none. 

The "Cover Texts" are certain short passages of text that are listed, 
as Front-Cover Texts or Back-Cover Texts, in the notice that says that 
the Document is released under this License.  A Front-Cover Text may 
be at most 5 words, and a Back-Cover Text may be at most 25 words. 

A "Transparent" copy of the Document means a machine-readable copy, 
represented in a format whose specification is available to the 
general public, that is suitable for revising the document 
straightforwardly with generic text editors or (for images composed of 
pixels) generic paint programs or (for drawings) some widely available 
drawing editor, and that is suitable for input to text formatters or 
for automatic translation to a variety of formats suitable for input 
to text formatters.  A copy made in an otherwise Transparent file 
format whose markup, or absence of markup, has been arranged to thwart 
or discourage subsequent modification by readers is not Transparent. 
An image format is not Transparent if used for any substantial amount 
of text.  A copy that is not "Transparent" is called "Opaque". 

Examples of suitable formats for Transparent copies include plain 
ASCII without markup, Texinfo input format, LaTeX input format, SGML 
or XML using a publicly available DTD, and standard-conforming simple 
HTML, PostScript or PDF designed for human modification.  Examples of 
transparent image formats include PNG, XCF and JPG.  Opaque formats 
include proprietary formats that can be read and edited only by 
proprietary word processors, SGML or XML for which the DTD and/or 
processing tools are not generally available, and the 
machine-generated HTML, PostScript or PDF produced by some word 
processors for output purposes only. 

The "Title Page" means, for a printed book, the title page itself, 
plus such following pages as are needed to hold, legibly, the material 
this License requires to appear in the title page.  For works in 
formats which do not have any title page as such, "Title Page" means 
the text near the most prominent appearance of the work's title, 
preceding the beginning of the body of the text. 

The "publisher" means any person or entity that distributes copies of 
the Document to the public. 

A section "Entitled XYZ" means a named subunit of the Document whose 
title either is precisely XYZ or contains XYZ in parentheses following 
text that translates XYZ in another language.  (Here XYZ stands for a 
specific section name mentioned below, such as "Acknowledgements", 
"Dedications", "Endorsements", or "History".)  To "Preserve the Title" 
of such a section when you modify the Document means that it remains a 
section "Entitled XYZ" according to this definition. 

The Document may include Warranty Disclaimers next to the notice which 
states that this License applies to the Document.  These Warranty 
Disclaimers are considered to be included by reference in this 
License, but only as regards disclaiming warranties: any other 
implication that these Warranty Disclaimers may have is void and has 
no effect on the meaning of this License. 

2. VERBATIM COPYING 

You may copy and distribute the Document in any medium, either 
commercially or noncommercially, provided that this License, the 
copyright notices, and the license notice saying this License applies 
to the Document are reproduced in all copies, and that you add no 
other conditions whatsoever to those of this License.  You may not use 
technical measures to obstruct or control the reading or further 
copying of the copies you make or distribute.  However, you may accept 
compensation in exchange for copies.  If you distribute a large enough 
number of copies you must also follow the conditions in section 3. 

You may also lend copies, under the same conditions stated above, and 
you may publicly display copies. 


3. COPYING IN QUANTITY 

If you publish printed copies (or copies in media that commonly have 
printed covers) of the Document, numbering more than 100, and the 
Document's license notice requires Cover Texts, you must enclose the 
copies in covers that carry, clearly and legibly, all these Cover 
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on 
the back cover.  Both covers must also clearly and legibly identify 
you as the publisher of these copies.  The front cover must present 
the full title with all words of the title equally prominent and 
visible.  You may add other material on the covers in addition. 
Copying with changes limited to the covers, as long as they preserve 
the title of the Document and satisfy these conditions, can be treated 
as verbatim copying in other respects. 

If the required texts for either cover are too voluminous to fit 
legibly, you should put the first ones listed (as many as fit 
reasonably) on the actual cover, and continue the rest onto adjacent 
pages. 

If you publish or distribute Opaque copies of the Document numbering 
more than 100, you must either include a machine-readable Transparent 
copy along with each Opaque copy, or state in or with each Opaque copy 
a computer-network location from which the general network-using 
public has access to download using public-standard network protocols 
a complete Transparent copy of the Document, free of added material. 
If you use the latter option, you must take reasonably prudent steps, 
when you begin distribution of Opaque copies in quantity, to ensure 
that this Transparent copy will remain thus accessible at the stated 
location until at least one year after the last time you distribute an 
Opaque copy (directly or through your agents or retailers) of that 
edition to the public. 

It is requested, but not required, that you contact the authors of the 
Document well before redistributing any large number of copies, to 
give them a chance to provide you with an updated version of the 
Document. 


4. MODIFICATIONS 

You may copy and distribute a Modified Version of the Document under 
the conditions of sections 2 and 3 above, provided that you release 
the Modified Version under precisely this License, with the Modified 
Version filling the role of the Document, thus licensing distribution 
and modification of the Modified Version to whoever possesses a copy 
of it.  In addition, you must do these things in the Modified Version: 

A. Use in the Title Page (and on the covers, if any) a title distinct 
  from that of the Document, and from those of previous versions 
  (which should, if there were any, be listed in the History section 
  of the Document).  You may use the same title as a previous version 
  if the original publisher of that version gives permission. 
B. List on the Title Page, as authors, one or more persons or entities 
  responsible for authorship of the modifications in the Modified 
  Version, together with at least five of the principal authors of the 
  Document (all of its principal authors, if it has fewer than five), 
  unless they release you from this requirement. 
C. State on the Title page the name of the publisher of the 
  Modified Version, as the publisher. 
D. Preserve all the copyright notices of the Document. 
E. Add an appropriate copyright notice for your modifications 
  adjacent to the other copyright notices. 
F. Include, immediately after the copyright notices, a license notice 
  giving the public permission to use the Modified Version under the 
  terms of this License, in the form shown in the Addendum below. 
G. Preserve in that license notice the full lists of Invariant Sections 
  and required Cover Texts given in the Document's license notice. 
H. Include an unaltered copy of this License. 
I. Preserve the section Entitled "History", Preserve its Title, and add 
  to it an item stating at least the title, year, new authors, and 
  publisher of the Modified Version as given on the Title Page.  If 
  there is no section Entitled "History" in the Document, create one 
  stating the title, year, authors, and publisher of the Document as 
  given on its Title Page, then add an item describing the Modified 
  Version as stated in the previous sentence. 
J. Preserve the network location, if any, given in the Document for 
  public access to a Transparent copy of the Document, and likewise 
  the network locations given in the Document for previous versions 
  it was based on.  These may be placed in the "History" section. 
  You may omit a network location for a work that was published at 
  least four years before the Document itself, or if the original 
  publisher of the version it refers to gives permission. 
K. For any section Entitled "Acknowledgements" or "Dedications", 
  Preserve the Title of the section, and preserve in the section all 
  the substance and tone of each of the contributor acknowledgements 
  and/or dedications given therein. 
L. Preserve all the Invariant Sections of the Document, 
  unaltered in their text and in their titles.  Section numbers 
  or the equivalent are not considered part of the section titles. 
M. Delete any section Entitled "Endorsements".  Such a section 
  may not be included in the Modified Version. 
N. Do not retitle any existing section to be Entitled "Endorsements" 
  or to conflict in title with any Invariant Section. 
O. Preserve any Warranty Disclaimers. 

If the Modified Version includes new front-matter sections or 
appendices that qualify as Secondary Sections and contain no material 
copied from the Document, you may at your option designate some or all 
of these sections as invariant.  To do this, add their titles to the 
list of Invariant Sections in the Modified Version's license notice. 
These titles must be distinct from any other section titles. 

You may add a section Entitled "Endorsements", provided it contains 
nothing but endorsements of your Modified Version by various 
parties--for example, statements of peer review or that the text has 
been approved by an organization as the authoritative definition of a 
standard. 

You may add a passage of up to five words as a Front-Cover Text, and a 
passage of up to 25 words as a Back-Cover Text, to the end of the list 
of Cover Texts in the Modified Version.  Only one passage of 
Front-Cover Text and one of Back-Cover Text may be added by (or 
through arrangements made by) any one entity.  If the Document already 
includes a cover text for the same cover, previously added by you or 
by arrangement made by the same entity you are acting on behalf of, 
you may not add another; but you may replace the old one, on explicit 
permission from the previous publisher that added the old one. 

The author(s) and publisher(s) of the Document do not by this License 
give permission to use their names for publicity for or to assert or 
imply endorsement of any Modified Version. 


5. COMBINING DOCUMENTS 

You may combine the Document with other documents released under this 
License, under the terms defined in section 4 above for modified 
versions, provided that you include in the combination all of the 
Invariant Sections of all of the original documents, unmodified, and 
list them all as Invariant Sections of your combined work in its 
license notice, and that you preserve all their Warranty Disclaimers. 

The combined work need only contain one copy of this License, and 
multiple identical Invariant Sections may be replaced with a single 
copy.  If there are multiple Invariant Sections with the same name but 
different contents, make the title of each such section unique by 
adding at the end of it, in parentheses, the name of the original 
author or publisher of that section if known, or else a unique number. 
Make the same adjustment to the section titles in the list of 
Invariant Sections in the license notice of the combined work. 

In the combination, you must combine any sections Entitled "History" 
in the various original documents, forming one section Entitled 
"History"; likewise combine any sections Entitled "Acknowledgements", 
and any sections Entitled "Dedications".  You must delete all sections 
Entitled "Endorsements". 


6. COLLECTIONS OF DOCUMENTS 

You may make a collection consisting of the Document and other 
documents released under this License, and replace the individual 
copies of this License in the various documents with a single copy 
that is included in the collection, provided that you follow the rules 
of this License for verbatim copying of each of the documents in all 
other respects. 

You may extract a single document from such a collection, and 
distribute it individually under this License, provided you insert a 
copy of this License into the extracted document, and follow this 
License in all other respects regarding verbatim copying of that 
document. 


7. AGGREGATION WITH INDEPENDENT WORKS 

A compilation of the Document or its derivatives with other separate 
and independent documents or works, in or on a volume of a storage or 
distribution medium, is called an "aggregate" if the copyright 
resulting from the compilation is not used to limit the legal rights 
of the compilation's users beyond what the individual works permit. 
When the Document is included in an aggregate, this License does not 
apply to the other works in the aggregate which are not themselves 
derivative works of the Document. 

If the Cover Text requirement of section 3 is applicable to these 
copies of the Document, then if the Document is less than one half of 
the entire aggregate, the Document's Cover Texts may be placed on 
covers that bracket the Document within the aggregate, or the 
electronic equivalent of covers if the Document is in electronic form. 
Otherwise they must appear on printed covers that bracket the whole 
aggregate. 


8. TRANSLATION 

Translation is considered a kind of modification, so you may 
distribute translations of the Document under the terms of section 4. 
Replacing Invariant Sections with translations requires special 
permission from their copyright holders, but you may include 
translations of some or all Invariant Sections in addition to the 
original versions of these Invariant Sections.  You may include a 
translation of this License, and all the license notices in the 
Document, and any Warranty Disclaimers, provided that you also include 
the original English version of this License and the original versions 
of those notices and disclaimers.  In case of a disagreement between 
the translation and the original version of this License or a notice 
or disclaimer, the original version will prevail. 

If a section in the Document is Entitled "Acknowledgements", 
"Dedications", or "History", the requirement (section 4) to Preserve 
its Title (section 1) will typically require changing the actual 
title. 


9. TERMINATION 

You may not copy, modify, sublicense, or distribute the Document 
except as expressly provided under this License.  Any attempt 
otherwise to copy, modify, sublicense, or distribute it is void, and 
will automatically terminate your rights under this License. 

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, receipt of a copy of some or all of the same material does 
not give you any rights to use it. 


10. FUTURE REVISIONS OF THIS LICENSE 

The Free Software Foundation may publish new, revised versions of the 
GNU Free Documentation 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.  See 
http://www.gnu.org/copyleft/. 

Each version of the License is given a distinguishing version number. 
If the Document specifies that a particular numbered version of this 
License "or any later version" applies to it, you have the option of 
following the terms and conditions either of that specified version or 
of any later version that has been published (not as a draft) by the 
Free Software Foundation.  If the Document does not specify a version 
number of this License, you may choose any version ever published (not 
as a draft) by the Free Software Foundation.  If the Document 
specifies that a proxy can decide which future versions of this 
License can be used, that proxy's public statement of acceptance of a 
version permanently authorizes you to choose that version for the 
Document. 

11. RELICENSING 

"Massive Multiauthor Collaboration Site" (or "MMC Site") means any 
World Wide Web server that publishes copyrightable works and also 
provides prominent facilities for anybody to edit those works.  A 
public wiki that anybody can edit is an example of such a server.  A 
"Massive Multiauthor Collaboration" (or "MMC") contained in the site 
means any set of copyrightable works thus published on the MMC site. 

"CC-BY-SA" means the Creative Commons Attribution-Share Alike 3.0  
license published by Creative Commons Corporation, a not-for-profit  
corporation with a principal place of business in San Francisco,  
California, as well as future copyleft versions of that license  
published by that same organization. 

"Incorporate" means to publish or republish a Document, in whole or in  
part, as part of another Document. 

An MMC is "eligible for relicensing" if it is licensed under this  
License, and if all works that were first published under this License  
somewhere other than this MMC, and subsequently incorporated in whole or  
in part into the MMC, (1) had no cover texts or invariant sections, and  
(2) were thus incorporated prior to November 1, 2008. 

The operator of an MMC Site may republish an MMC contained in the site 
under CC-BY-SA on the same site at any time before August 1, 2009, 
provided the MMC is eligible for relicensing. 


ADDENDUM: How to use this License for your documents 

To use this License in a document you have written, include a copy of 
the License in the document and put the following copyright and 
license notices just after the title page: 

   Copyright (c)  YEAR  YOUR NAME. 
   Permission is granted to copy, distribute and/or modify this document 
   under the terms of the GNU Free Documentation License, Version 1.3 
   or any later version published by the Free Software Foundation; 
   with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts. 
   A copy of the license is included in the section entitled "GNU 
   Free Documentation License". 

If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, 
replace the "with...Texts." line with this: 

   with the Invariant Sections being LIST THEIR TITLES, with the 
   Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST. 

If you have Invariant Sections without Cover Texts, or some other 
combination of the three, merge those two alternatives to suit the 
situation. 

If your document contains nontrivial examples of program code, we 
recommend releasing these examples in parallel under your choice of 
free software license, such as the GNU General Public License, 
to permit their use in free software. 
                   GNU GENERAL PUBLIC LICENSE 
                      Version 2, June 1991 

Copyright (C) 1989, 1991 Free Software Foundation, Inc., 
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA 
Everyone is permitted to copy and distribute verbatim copies 
of this license document, but changing it is not allowed. 

                           Preamble 

 The licenses for most software are designed to take away your 
freedom to share and change it.  By contrast, the GNU General Public 
License is intended to guarantee your freedom to share and change free 
software--to make sure the software is free for all its users.  This 
General Public License applies to most of the Free 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 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 
this service 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 make restrictions that forbid 
anyone to deny you these rights or to ask you to surrender the rights. 
These restrictions translate to certain responsibilities for you if you 
distribute copies of the software, or if you modify it. 

 For example, if you distribute copies 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 so they know their 
rights. 

 We protect your rights with two steps: (1) copyright the software, and 
(2) offer you this license which gives you legal permission to copy, 
distribute and/or modify the software. 

 Also, for each author's protection and ours, 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 any problems introduced by others will not reflect on the original 
authors' reputations. 

 Finally, any free program is threatened constantly by software 
patents.  We wish to avoid the danger that redistributors of a free 
program will individually obtain patent licenses, in effect making the 
program proprietary.  To prevent this, we have made it clear that any 
patent must be licensed for everyone's free use or not licensed at all. 

 The precise terms and conditions for copying, distribution and 
modification follow. 

                   GNU GENERAL PUBLIC LICENSE 
  TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 

 0. This License applies to any program or other work which contains 
a notice placed by the copyright holder saying it may be distributed 
under the terms of this General Public License.  The "Program", below, 
refers to any such program or work, and a "work based on the Program" 
means either the Program or any derivative work under copyright law: 
that is to say, a work containing the Program or a portion of it, 
either verbatim or with modifications and/or translated into another 
language.  (Hereinafter, translation is included without limitation in 
the term "modification".)  Each licensee is addressed as "you". 

Activities other than copying, distribution and modification are not 
covered 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 (independent of having been made by running the Program). 
Whether that is true depends on what the Program does. 

 1. You may copy and distribute 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 and disclaimer of warranty; keep intact all the 
notices that refer to this License and to the absence of any warranty; 
and give any other recipients of the Program a copy of this License 
along with the Program. 

You may charge a fee for the physical act of transferring a copy, and 
you may at your option offer warranty protection in exchange for a fee. 

 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 
distribute 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 files to carry prominent notices 
   stating that you changed the files and the date of any change. 

   b) You must cause any work that you distribute or publish, that in 
   whole or in part contains or is derived from the Program or any 
   part thereof, to be licensed as a whole at no charge to all third 
   parties under the terms of this License. 

   c) If the modified program normally reads commands interactively 
   when run, you must cause it, when started running for such 
   interactive use in the most ordinary way, to print or display an 
   announcement including an appropriate copyright notice and a 
   notice that there is no warranty (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.  (Exception: 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 
identifiable sections of that work are not derived from the Program, 
and can be reasonably considered independent and separate works in 
themselves, 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 is a work based 
on the Program, the distribution of the whole must be on the terms of 
this License, whose 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 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, 
under Section 2) in object code or executable form under the terms of 
Sections 1 and 2 above provided that you also do one of the following: 

   a) Accompany it with the complete corresponding machine-readable 
   source code, which must be distributed under 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 give any third party, for a charge no more than your 
   cost of physically performing 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 medium 
   customarily used for software interchange; or, 

   c) Accompany it with the information you received as to the offer 
   to distribute corresponding source code.  (This alternative is 
   allowed only for noncommercial distribution and only if you 
   received the program in object code or executable form with such 
   an offer, in accord with Subsection b above.) 

The source code for a work means the preferred form of the work for 
making modifications to it.  For an executable work, complete source 
code means all the source code for all modules it contains, plus any 
associated interface definition files, plus the scripts used to 
control compilation and installation of the executable.  However, as a 
special exception, the source code distributed need not include 
anything that is normally distributed (in either source or binary 
form) with the major components (compiler, kernel, and so on) of the 
operating system on which the executable runs, unless that component 
itself accompanies the executable. 

If distribution of executable or object code is made by offering 
access to copy from a designated place, then offering equivalent 
access to copy the source code from the same place counts as 
distribution of the source code, even though third parties are not 
compelled to copy the source along with the object code. 

 4. You may not copy, modify, sublicense, or distribute the Program 
except as expressly provided under this License.  Any attempt 
otherwise to copy, modify, sublicense or distribute the Program is 
void, and will automatically terminate your rights under this License. 
However, parties who have received copies, or rights, from you under 
this License will not have their licenses terminated so long as such 
parties remain in full compliance. 

 5. You are not required to accept this License, since you have not 
signed it.  However, nothing else grants you permission to modify or 
distribute 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 based on the 
Program), you indicate your acceptance of this License to do so, and 
all its terms and conditions for copying, distributing or modifying 
the Program or works based on it. 

 6. Each time you redistribute the Program (or any work based on the 
Program), the recipient automatically receives a license from the 
original licensor 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 granted herein. 
You are not responsible for enforcing compliance by third parties to 
this License. 

 7. If, as a consequence of a court judgment or allegation of patent 
infringement or for any other reason (not limited to patent issues), 
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 
distribute so as to satisfy simultaneously your obligations 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 royalty-free redistribution of the Program 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 distribution of the Program. 

If any portion of this section is held invalid 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 
circumstances. 

It is not the purpose of this section to induce you to infringe any 
patents or other property right claims or to contest validity of any 
such claims; this section has the sole purpose of protecting the 
integrity of the free software distribution system, which is 
implemented by public license practices.  Many people have made 
generous contributions to the wide range of software distributed 
through that system in reliance on consistent application of that 
system; it is up to the author/donor to decide if he or she is willing 
to distribute software through any other system and a licensee cannot 
impose that choice. 

This section is intended to make thoroughly 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 countries either by patents or by copyrighted interfaces, the 
original copyright holder who places the Program under this License 
may add an explicit geographical distribution limitation excluding 
those countries, so that distribution is permitted only in or among 
countries not thus excluded.  In such case, this License incorporates 
the limitation as if written in the body of this License. 

 9. The Free Software Foundation may publish revised and/or new versions 
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 version number.  If the Program 
specifies a version number of this License which 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 Program does 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 
programs whose distribution conditions are different, 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 sometimes 
make exceptions for this.  Our decision will be guided by the two goals 
of preserving the free status of all derivatives of our free software and 
of promoting the sharing and reuse of software generally. 

                           NO WARRANTY 

 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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. 

 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR 
REDISTRIBUTE 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. 

                    END OF TERMS AND CONDITIONS 

           How to Apply These Terms to Your New Programs 

 If you develop a new program, and you want it to be of the greatest 
possible use to the public, the best way to achieve this is to make it 
free software which everyone can redistribute and change under these terms. 

 To do so, attach the following notices to the program.  It is safest 
to attach them to the start of each source file to most effectively 
convey the exclusion of warranty; and each file should have at least 
the "copyright" line and a pointer to where the full notice is found. 

   <one line to give the program's name and a brief idea of what it does.> 
   Copyright (C) <year>  <name of author> 

   This program is free software; you can redistribute it and/or modify 
   it under the terms of the GNU General Public License as published by 
   the Free Software Foundation; either version 2 of the License, or 
   (at your option) any later version. 

   This program is distributed in the hope that it will be useful, 
   but WITHOUT ANY WARRANTY; without even the implied warranty of 
   MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the 
   GNU General Public License for more details. 

   You should have received a copy of the GNU General Public License along 
   with this program; if not, write to the Free Software Foundation, Inc., 
   51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. 

Also add information on how to contact you by electronic and paper mail. 

If the program is interactive, make it output a short notice like this 
when it starts in an interactive mode: 

   Gnomovision version 69, Copyright (C) year name of author 
   Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 
   This is free software, and you are welcome to redistribute it 
   under certain conditions; type `show c' for details. 

The hypothetical commands `show w' and `show c' should show the appropriate 
parts of the General Public License.  Of course, the commands you use may 
be called something other than `show w' and `show c'; they could even be 
mouse-clicks or menu items--whatever suits your program. 

You should also get your employer (if you work as a programmer) or your 
school, if any, to sign a "copyright disclaimer" for the program, if 
necessary.  Here is a sample; alter the names: 

 Yoyodyne, Inc., hereby disclaims all copyright interest in the program 
 `Gnomovision' (which makes passes at compilers) written by James Hacker. 

 <signature of Ty Coon>, 1 April 1989 
 Ty Coon, President of Vice 

This General Public License does not permit incorporating your program into 
proprietary programs.  If your program is a subroutine library, you may 
consider it more useful to permit linking proprietary applications with the 
library.  If this is what you want to do, use the GNU Lesser General 
Public License instead of this License.

                   GNU GENERAL PUBLIC LICENSE 
                      Version 3, 29 June 2007 

Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 
Everyone is permitted to copy and distribute verbatim copies 
of this license document, but changing it is not allowed. 

                           Preamble 

 The GNU General Public License is a free, copyleft license for 
software and other kinds of works. 

 The licenses for most software and other practical works are designed 
to take away your freedom to share and change the works.  By contrast, 
the GNU General Public License is intended to guarantee your freedom to 
share and change all versions of a program--to make sure it remains free 
software for all its users.  We, the Free Software Foundation, use the 
GNU General Public License for most of our software; it applies also to 
any other work released this way by its authors.  You can apply it to 
your programs, too. 

 When we speak of free software, we are referring to freedom, not 
price.  Our General Public Licenses are designed to make sure that you 
have the freedom to distribute copies of free software (and charge for 
them if you wish), that you receive source code or can get it if you 
want it, that you can change the software or use pieces of it in new 
free programs, and that you know you can do these things. 

 To protect your rights, we need to prevent others from denying you 
these rights or asking you to surrender the rights.  Therefore, you have 
certain responsibilities if you distribute copies of the software, or if 
you modify it: responsibilities to respect the freedom of others. 

 For example, if you distribute copies of such a program, whether 
gratis or for a fee, you must pass on to the recipients the same 
freedoms that you received.  You must make sure that they, too, receive 
or can get the source code.  And you must show them these terms so they 
know their rights. 

 Developers that use the GNU GPL protect your rights with two steps: 
(1) assert copyright on the software, and (2) offer you this License 
giving you legal permission to copy, distribute and/or modify it. 

 For the developers' and authors' protection, the GPL clearly explains 
that there is no warranty for this free software.  For both users' and 
authors' sake, the GPL requires that modified versions be marked as 
changed, so that their problems will not be attributed erroneously to 
authors of previous versions. 

 Some devices are designed to deny users access to install or run 
modified versions of the software inside them, although the manufacturer 
can do so.  This is fundamentally incompatible with the aim of 
protecting users' freedom to change the software.  The systematic 
pattern of such abuse occurs in the area of products for individuals to 
use, which is precisely where it is most unacceptable.  Therefore, we 
have designed this version of the GPL to prohibit the practice for those 
products.  If such problems arise substantially in other domains, we 
stand ready to extend this provision to those domains in future versions 
of the GPL, as needed to protect the freedom of users. 

 Finally, every program is threatened constantly by software patents. 
States should not allow patents to restrict development and use of 
software on general-purpose computers, but in those that do, we wish to 
avoid the special danger that patents applied to a free program could 
make it effectively proprietary.  To prevent this, the GPL assures that 
patents cannot be used to render the program non-free. 

 The precise terms and conditions for copying, distribution and 
modification follow. 

                      TERMS AND CONDITIONS 

 0. Definitions. 

 "This License" refers to version 3 of the GNU General Public License. 

 "Copyright" also means copyright-like laws that apply to other kinds of 
works, such as semiconductor masks. 

 "The Program" refers to any copyrightable work licensed under this 
License.  Each licensee is addressed as "you".  "Licensees" and 
"recipients" may be individuals or organizations. 

 To "modify" a work means to copy from or adapt all or part of the work 
in a fashion requiring copyright permission, other than the making of an 
exact copy.  The resulting work is called a "modified version" of the 
earlier work or a work "based on" the earlier work. 

 A "covered work" means either the unmodified Program or a work based 
on the Program. 

 To "propagate" a work means to do anything with it that, without 
permission, would make you directly or secondarily liable for 
infringement under applicable copyright law, except executing it on a 
computer or modifying a private copy.  Propagation includes copying, 
distribution (with or without modification), making available to the 
public, and in some countries other activities as well. 

 To "convey" a work means any kind of propagation that enables other 
parties to make or receive copies.  Mere interaction with a user through 
a computer network, with no transfer of a copy, is not conveying. 

 An interactive user interface displays "Appropriate Legal Notices" 
to the extent that it includes a convenient and prominently visible 
feature that (1) displays an appropriate copyright notice, and (2) 
tells the user that there is no warranty for the work (except to the 
extent that warranties are provided), that licensees may convey the 
work under this License, and how to view a copy of this License.  If 
the interface presents a list of user commands or options, such as a 
menu, a prominent item in the list meets this criterion. 

 1. Source Code. 

 The "source code" for a work means the preferred form of the work 
for making modifications to it.  "Object code" means any non-source 
form of a work. 

 A "Standard Interface" means an interface that either is an official 
standard defined by a recognized standards body, or, in the case of 
interfaces specified for a particular programming language, one that 
is widely used among developers working in that language. 

 The "System Libraries" of an executable work include anything, other 
than the work as a whole, that (a) is included in the normal form of 
packaging a Major Component, but which is not part of that Major 
Component, and (b) serves only to enable use of the work with that 
Major Component, or to implement a Standard Interface for which an 
implementation is available to the public in source code form.  A 
"Major Component", in this context, means a major essential component 
(kernel, window system, and so on) of the specific operating system 
(if any) on which the executable work runs, or a compiler used to 
produce the work, or an object code interpreter used to run it. 

 The "Corresponding Source" for a work in object code form means all 
the source code needed to generate, install, and (for an executable 
work) run the object code and to modify the work, including scripts to 
control those activities.  However, it does not include the work's 
System Libraries, or general-purpose tools or generally available free 
programs which are used unmodified in performing those activities but 
which are not part of the work.  For example, Corresponding Source 
includes interface definition files associated with source files for 
the work, and the source code for shared libraries and dynamically 
linked subprograms that the work is specifically designed to require, 
such as by intimate data communication or control flow between those 
subprograms and other parts of the work. 

 The Corresponding Source need not include anything that users 
can regenerate automatically from other parts of the Corresponding 
Source. 

 The Corresponding Source for a work in source code form is that 
same work. 

 2. Basic Permissions. 

 All rights granted under this License are granted for the term of 
copyright on the Program, and are irrevocable provided the stated 
conditions are met.  This License explicitly affirms your unlimited 
permission to run the unmodified Program.  The output from running a 
covered work is covered by this License only if the output, given its 
content, constitutes a covered work.  This License acknowledges your 
rights of fair use or other equivalent, as provided by copyright law. 

 You may make, run and propagate covered works that you do not 
convey, without conditions so long as your license otherwise remains 
in force.  You may convey covered works to others for the sole purpose 
of having them make modifications exclusively for you, or provide you 
with facilities for running those works, provided that you comply with 
the terms of this License in conveying all material for which you do 
not control copyright.  Those thus making or running the covered works 
for you must do so exclusively on your behalf, under your direction 
and control, on terms that prohibit them from making any copies of 
your copyrighted material outside their relationship with you. 

 Conveying under any other circumstances is permitted solely under 
the conditions stated below.  Sublicensing is not allowed; section 10 
makes it unnecessary. 

 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 

 No covered work shall be deemed part of an effective technological 
measure under any applicable law fulfilling obligations under article 
11 of the WIPO copyright treaty adopted on 20 December 1996, or 
similar laws prohibiting or restricting circumvention of such 
measures. 

 When you convey a covered work, you waive any legal power to forbid 
circumvention of technological measures to the extent such circumvention 
is effected by exercising rights under this License with respect to 
the covered work, and you disclaim any intention to limit operation or 
modification of the work as a means of enforcing, against the work's 
users, your or third parties' legal rights to forbid circumvention of 
technological measures. 

 4. Conveying Verbatim Copies. 

 You may convey verbatim copies of the Program's source code as you 
receive it, in any medium, provided that you conspicuously and 
appropriately publish on each copy an appropriate copyright notice; 
keep intact all notices stating that this License and any 
non-permissive terms added in accord with section 7 apply to the code; 
keep intact all notices of the absence of any warranty; and give all 
recipients a copy of this License along with the Program. 

 You may charge any price or no price for each copy that you convey, 
and you may offer support or warranty protection for a fee. 

 5. Conveying Modified Source Versions. 

 You may convey a work based on the Program, or the modifications to 
produce it from the Program, in the form of source code under the 
terms of section 4, provided that you also meet all of these conditions: 

   a) The work must carry prominent notices stating that you modified 
   it, and giving a relevant date. 

   b) The work must carry prominent notices stating that it is 
   released under this License and any conditions added under section 
   7.  This requirement modifies the requirement in section 4 to 
   "keep intact all notices". 

   c) You must license the entire work, as a whole, under this 
   License to anyone who comes into possession of a copy.  This 
   License will therefore apply, along with any applicable section 7 
   additional terms, to the whole of the work, and all its parts, 
   regardless of how they are packaged.  This License gives no 
   permission to license the work in any other way, but it does not 
   invalidate such permission if you have separately received it. 

   d) If the work has interactive user interfaces, each must display 
   Appropriate Legal Notices; however, if the Program has interactive 
   interfaces that do not display Appropriate Legal Notices, your 
   work need not make them do so. 

 A compilation of a covered work with other separate and independent 
works, which are not by their nature extensions of the covered work, 
and which are not combined with it such as to form a larger program, 
in or on a volume of a storage or distribution medium, is called an 
"aggregate" if the compilation and its resulting copyright are not 
used to limit the access or legal rights of the compilation's users 
beyond what the individual works permit.  Inclusion of a covered work 
in an aggregate does not cause this License to apply to the other 
parts of the aggregate. 

 6. Conveying Non-Source Forms. 

 You may convey a covered work in object code form under the terms 
of sections 4 and 5, provided that you also convey the 
machine-readable Corresponding Source under the terms of this License, 
in one of these ways: 

   a) Convey the object code in, or embodied in, a physical product 
   (including a physical distribution medium), accompanied by the 
   Corresponding Source fixed on a durable physical medium 
   customarily used for software interchange. 

   b) Convey the object code in, or embodied in, a physical product 
   (including a physical distribution medium), accompanied by a 
   written offer, valid for at least three years and valid for as 
   long as you offer spare parts or customer support for that product 
   model, to give anyone who possesses the object code either (1) a 
   copy of the Corresponding Source for all the software in the 
   product that is covered by this License, on a durable physical 
   medium customarily used for software interchange, for a price no 
   more than your reasonable cost of physically performing this 
   conveying of source, or (2) access to copy the 
   Corresponding Source from a network server at no charge. 

   c) Convey individual copies of the object code with a copy of the 
   written offer to provide the Corresponding Source.  This 
   alternative is allowed only occasionally and noncommercially, and 
   only if you received the object code with such an offer, in accord 
   with subsection 6b. 

   d) Convey the object code by offering access from a designated 
   place (gratis or for a charge), and offer equivalent access to the 
   Corresponding Source in the same way through the same place at no 
   further charge.  You need not require recipients to copy the 
   Corresponding Source along with the object code.  If the place to 
   copy the object code is a network server, the Corresponding Source 
   may be on a different server (operated by you or a third party) 
   that supports equivalent copying facilities, provided you maintain 
   clear directions next to the object code saying where to find the 
   Corresponding Source.  Regardless of what server hosts the 
   Corresponding Source, you remain obligated to ensure that it is 
   available for as long as needed to satisfy these requirements. 

   e) Convey the object code using peer-to-peer transmission, provided 
   you inform other peers where the object code and Corresponding 
   Source of the work are being offered to the general public at no 
   charge under subsection 6d. 

 A separable portion of the object code, whose source code is excluded 
from the Corresponding Source as a System Library, need not be 
included in conveying the object code work. 

 A "User Product" is either (1) a "consumer product", which means any 
tangible personal property which is normally used for personal, family, 
or household purposes, or (2) anything designed or sold for incorporation 
into a dwelling.  In determining whether a product is a consumer product, 
doubtful cases shall be resolved in favor of coverage.  For a particular 
product received by a particular user, "normally used" refers to a 
typical or common use of that class of product, regardless of the status 
of the particular user or of the way in which the particular user 
actually uses, or expects or is expected to use, the product.  A product 
is a consumer product regardless of whether the product has substantial 
commercial, industrial or non-consumer uses, unless such uses represent 
the only significant mode of use of the product. 

 "Installation Information" for a User Product means any methods, 
procedures, authorization keys, or other information required to install 
and execute modified versions of a covered work in that User Product from 
a modified version of its Corresponding Source.  The information must 
suffice to ensure that the continued functioning of the modified object 
code is in no case prevented or interfered with solely because 
modification has been made. 

 If you convey an object code work under this section in, or with, or 
specifically for use in, a User Product, and the conveying occurs as 
part of a transaction in which the right of possession and use of the 
User Product is transferred to the recipient in perpetuity or for a 
fixed term (regardless of how the transaction is characterized), the 
Corresponding Source conveyed under this section must be accompanied 
by the Installation Information.  But this requirement does not apply 
if neither you nor any third party retains the ability to install 
modified object code on the User Product (for example, the work has 
been installed in ROM). 

 The requirement to provide Installation Information does not include a 
requirement to continue to provide support service, warranty, or updates 
for a work that has been modified or installed by the recipient, or for 
the User Product in which it has been modified or installed.  Access to a 
network may be denied when the modification itself materially and 
adversely affects the operation of the network or violates the rules and 
protocols for communication across the network. 

 Corresponding Source conveyed, and Installation Information provided, 
in accord with this section must be in a format that is publicly 
documented (and with an implementation available to the public in 
source code form), and must require no special password or key for 
unpacking, reading or copying. 

 7. Additional Terms. 

 "Additional permissions" are terms that supplement the terms of this 
License by making exceptions from one or more of its conditions. 
Additional permissions that are applicable to the entire Program shall 
be treated as though they were included in this License, to the extent 
that they are valid under applicable law.  If additional permissions 
apply only to part of the Program, that part may be used separately 
under those permissions, but the entire Program remains governed by 
this License without regard to the additional permissions. 

 When you convey a copy of a covered work, you may at your option 
remove any additional permissions from that copy, or from any part of 
it.  (Additional permissions may be written to require their own 
removal in certain cases when you modify the work.)  You may place 
additional permissions on material, added by you to a covered work, 
for which you have or can give appropriate copyright permission. 

 Notwithstanding any other provision of this License, for material you 
add to a covered work, you may (if authorized by the copyright holders of 
that material) supplement the terms of this License with terms: 

   a) Disclaiming warranty or limiting liability differently from the 
   terms of sections 15 and 16 of this License; or 

   b) Requiring preservation of specified reasonable legal notices or 
   author attributions in that material or in the Appropriate Legal 
   Notices displayed by works containing it; or 

   c) Prohibiting misrepresentation of the origin of that material, or 
   requiring that modified versions of such material be marked in 
   reasonable ways as different from the original version; or 

   d) Limiting the use for publicity purposes of names of licensors or 
   authors of the material; or 

   e) Declining to grant rights under trademark law for use of some 
   trade names, trademarks, or service marks; or 

   f) Requiring indemnification of licensors and authors of that 
   material by anyone who conveys the material (or modified versions of 
   it) with contractual assumptions of liability to the recipient, for 
   any liability that these contractual assumptions directly impose on 
   those licensors and authors. 

 All other non-permissive additional terms are considered "further 
restrictions" within the meaning of section 10.  If the Program as you 
received it, or any part of it, contains a notice stating that it is 
governed by this License along with a term that is a further 
restriction, you may remove that term.  If a license document contains 
a further restriction but permits relicensing or conveying under this 
License, you may add to a covered work material governed by the terms 
of that license document, provided that the further restriction does 
not survive such relicensing or conveying. 

 If you add terms to a covered work in accord with this section, you 
must place, in the relevant source files, a statement of the 
additional terms that apply to those files, or a notice indicating 
where to find the applicable terms. 

 Additional terms, permissive or non-permissive, may be stated in the 
form of a separately written license, or stated as exceptions; 
the above requirements apply either way. 

 8. Termination. 

 You may not propagate or modify a covered work except as expressly 
provided under this License.  Any attempt otherwise to propagate or 
modify it is void, and will automatically terminate your rights under 
this License (including any patent licenses granted under the third 
paragraph of section 11). 

 However, if you cease all violation of this License, then your 
license from a particular copyright holder is reinstated (a) 
provisionally, unless and until the copyright holder explicitly and 
finally terminates your license, and (b) permanently, if the copyright 
holder fails to notify you of the violation by some reasonable means 
prior to 60 days after the cessation. 

 Moreover, your license from a particular copyright holder is 
reinstated permanently if the copyright holder notifies you of the 
violation by some reasonable means, this is the first time you have 
received notice of violation of this License (for any work) from that 
copyright holder, and you cure the violation prior to 30 days after 
your receipt of the notice. 

 Termination of your rights under this section does not terminate the 
licenses of parties who have received copies or rights from you under 
this License.  If your rights have been terminated and not permanently 
reinstated, you do not qualify to receive new licenses for the same 
material under section 10. 

 9. Acceptance Not Required for Having Copies. 

 You are not required to accept this License in order to receive or 
run a copy of the Program.  Ancillary propagation of a covered work 
occurring solely as a consequence of using peer-to-peer transmission 
to receive a copy likewise does not require acceptance.  However, 
nothing other than this License grants you permission to propagate or 
modify any covered work.  These actions infringe copyright if you do 
not accept this License.  Therefore, by modifying or propagating a 
covered work, you indicate your acceptance of this License to do so. 

 10. Automatic Licensing of Downstream Recipients. 

 Each time you convey a covered work, the recipient automatically 
receives a license from the original licensors, to run, modify and 
propagate that work, subject to this License.  You are not responsible 
for enforcing compliance by third parties with this License. 

 An "entity transaction" is a transaction transferring control of an 
organization, or substantially all assets of one, or subdividing an 
organization, or merging organizations.  If propagation of a covered 
work results from an entity transaction, each party to that 
transaction who receives a copy of the work also receives whatever 
licenses to the work the party's predecessor in interest had or could 
give under the previous paragraph, plus a right to possession of the 
Corresponding Source of the work from the predecessor in interest, if 
the predecessor has it or can get it with reasonable efforts. 

 You may not impose any further restrictions on the exercise of the 
rights granted or affirmed under this License.  For example, you may 
not impose a license fee, royalty, or other charge for exercise of 
rights granted under this License, and you may not initiate litigation 
(including a cross-claim or counterclaim in a lawsuit) alleging that 
any patent claim is infringed by making, using, selling, offering for 
sale, or importing the Program or any portion of it. 

 11. Patents. 

 A "contributor" is a copyright holder who authorizes use under this 
License of the Program or a work on which the Program is based.  The 
work thus licensed is called the contributor's "contributor version". 

 A contributor's "essential patent claims" are all patent claims 
owned or controlled by the contributor, whether already acquired or 
hereafter acquired, that would be infringed by some manner, permitted 
by this License, of making, using, or selling its contributor version, 
but do not include claims that would be infringed only as a 
consequence of further modification of the contributor version.  For 
purposes of this definition, "control" includes the right to grant 
patent sublicenses in a manner consistent with the requirements of 
this License. 

 Each contributor grants you a non-exclusive, worldwide, royalty-free 
patent license under the contributor's essential patent claims, to 
make, use, sell, offer for sale, import and otherwise run, modify and 
propagate the contents of its contributor version. 

 In the following three paragraphs, a "patent license" is any express 
agreement or commitment, however denominated, not to enforce a patent 
(such as an express permission to practice a patent or covenant not to 
sue for patent infringement).  To "grant" such a patent license to a 
party means to make such an agreement or commitment not to enforce a 
patent against the party. 

 If you convey a covered work, knowingly relying on a patent license, 
and the Corresponding Source of the work is not available for anyone 
to copy, free of charge and under the terms of this License, through a 
publicly available network server or other readily accessible means, 
then you must either (1) cause the Corresponding Source to be so 
available, or (2) arrange to deprive yourself of the benefit of the 
patent license for this particular work, or (3) arrange, in a manner 
consistent with the requirements of this License, to extend the patent 
license to downstream recipients.  "Knowingly relying" means you have 
actual knowledge that, but for the patent license, your conveying the 
covered work in a country, or your recipient's use of the covered work 
in a country, would infringe one or more identifiable patents in that 
country that you have reason to believe are valid. 

 If, pursuant to or in connection with a single transaction or 
arrangement, you convey, or propagate by procuring conveyance of, a 
covered work, and grant a patent license to some of the parties 
receiving the covered work authorizing them to use, propagate, modify 
or convey a specific copy of the covered work, then the patent license 
you grant is automatically extended to all recipients of the covered 
work and works based on it. 

 A patent license is "discriminatory" if it does not include within 
the scope of its coverage, prohibits the exercise of, or is 
conditioned on the non-exercise of one or more of the rights that are 
specifically granted under this License.  You may not convey a covered 
work if you are a party to an arrangement with a third party that is 
in the business of distributing software, under which you make payment 
to the third party based on the extent of your activity of conveying 
the work, and under which the third party grants, to any of the 
parties who would receive the covered work from you, a discriminatory 
patent license (a) in connection with copies of the covered work 
conveyed by you (or copies made from those copies), or (b) primarily 
for and in connection with specific products or compilations that 
contain the covered work, unless you entered into that arrangement, 
or that patent license was granted, prior to 28 March 2007. 

 Nothing in this License shall be construed as excluding or limiting 
any implied license or other defenses to infringement that may 
otherwise be available to you under applicable patent law. 

 12. No Surrender of Others' Freedom. 

 If conditions are imposed on you (whether by court order, agreement or 
otherwise) that contradict the conditions of this License, they do not 
excuse you from the conditions of this License.  If you cannot convey a 
covered work so as to satisfy simultaneously your obligations under this 
License and any other pertinent obligations, then as a consequence you may 
not convey it at all.  For example, if you agree to terms that obligate you 
to collect a royalty for further conveying from those to whom you convey 
the Program, the only way you could satisfy both those terms and this 
License would be to refrain entirely from conveying the Program. 

 13. Use with the GNU Affero General Public License. 

 Notwithstanding any other provision of this License, you have 
permission to link or combine any covered work with a work licensed 
under version 3 of the GNU Affero General Public License into a single 
combined work, and to convey the resulting work.  The terms of this 
License will continue to apply to the part which is the covered work, 
but the special requirements of the GNU Affero General Public License, 
section 13, concerning interaction through a network will apply to the 
combination as such. 

 14. Revised Versions of this License. 

 The Free Software Foundation may publish revised and/or new versions of 
the GNU General Public License from time to time.  Such new versions will 
be similar in spirit to the present version, but may differ in detail to 
address new problems or concerns. 

 Each version is given a distinguishing version number.  If the 
Program specifies that a certain numbered version of the GNU General 
Public License "or any later version" applies to it, you have the 
option of following the terms and conditions either of that numbered 
version or of any later version published by the Free Software 
Foundation.  If the Program does not specify a version number of the 
GNU General Public License, you may choose any version ever published 
by the Free Software Foundation. 

 If the Program specifies that a proxy can decide which future 
versions of the GNU General Public License can be used, that proxy's 
public statement of acceptance of a version permanently authorizes you 
to choose that version for the Program. 

 Later license versions may give you additional or different 
permissions.  However, no additional obligations are imposed on any 
author or copyright holder as a result of your choosing to follow a 
later version. 

 15. Disclaimer of Warranty. 

 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 
ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 

 16. Limitation of Liability. 

 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 
SUCH DAMAGES. 

 17. Interpretation of Sections 15 and 16. 

 If the disclaimer of warranty and limitation of liability provided 
above cannot be given local legal effect according to their terms, 
reviewing courts shall apply local law that most closely approximates 
an absolute waiver of all civil liability in connection with the 
Program, unless a warranty or assumption of liability accompanies a 
copy of the Program in return for a fee. 

                    END OF TERMS AND CONDITIONS 

           How to Apply These Terms to Your New Programs 

 If you develop a new program, and you want it to be of the greatest 
possible use to the public, the best way to achieve this is to make it 
free software which everyone can redistribute and change under these terms. 

 To do so, attach the following notices to the program.  It is safest 
to attach them to the start of each source file to most effectively 
state the exclusion of warranty; and each file should have at least 
the "copyright" line and a pointer to where the full notice is found. 

   <one line to give the program's name and a brief idea of what it does.> 
   Copyright (C) <year>  <name of author> 

   This program is free software: you can redistribute it and/or modify 
   it under the terms of the GNU General Public License as published by 
   the Free Software Foundation, either version 3 of the License, or 
   (at your option) any later version. 

   This program is distributed in the hope that it will be useful, 
   but WITHOUT ANY WARRANTY; without even the implied warranty of 
   MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the 
   GNU General Public License for more details. 

   You should have received a copy of the GNU General Public License 
   along with this program.  If not, see <http://www.gnu.org/licenses/>. 

Also add information on how to contact you by electronic and paper mail. 

 If the program does terminal interaction, make it output a short 
notice like this when it starts in an interactive mode: 

   <program>  Copyright (C) <year>  <name of author> 
   This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 
   This is free software, and you are welcome to redistribute it 
   under certain conditions; type `show c' for details. 

The hypothetical commands `show w' and `show c' should show the appropriate 
parts of the General Public License.  Of course, your program's commands 
might be different; for a GUI interface, you would use an "about box". 

 You should also get your employer (if you work as a programmer) or school, 
if any, to sign a "copyright disclaimer" for the program, if necessary. 
For more information on this, and how to apply and follow the GNU GPL, see 
<http://www.gnu.org/licenses/>. 

 The GNU General Public License does not permit incorporating your program 
into proprietary programs.  If your program is a subroutine library, you 
may consider it more useful to permit linking proprietary applications with 
the library.  If this is what you want to do, use the GNU Lesser General 
Public License instead of this License.  But first, please read 
<http://www.gnu.org/philosophy/why-not-lgpl.html>. 
This is the GNU General Public License version 3, annotated with The 
Qt Company GPL Exception 1.0:

The Qt Company GPL Exception 1.0 

Exception 1: 

As a special exception you may create a larger work which contains the 
output of this application and distribute that work under terms of your 
choice, so long as the work is not otherwise derived from or based on 
this application and so long as the work does not in itself generate 
output that contains the output from this application in its original 
or modified form. 

Exception 2: 

As a special exception, you have permission to combine this application 
with Plugins licensed under the terms of your choice, to produce an 
executable, and to copy and distribute the resulting executable under 
the terms of your choice. However, the executable must be accompanied 
by a prominent notice offering all users of the executable the entire 
source code to this application, excluding the source code of the 
independent modules, but including any changes you have made to this 
application, under the terms of this license.

                   GNU GENERAL PUBLIC LICENSE 
                      Version 3, 29 June 2007 

Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 
Everyone is permitted to copy and distribute verbatim copies 
of this license document, but changing it is not allowed. 

                           Preamble 

 The GNU General Public License is a free, copyleft license for 
software and other kinds of works. 

 The licenses for most software and other practical works are designed 
to take away your freedom to share and change the works.  By contrast, 
the GNU General Public License is intended to guarantee your freedom to 
share and change all versions of a program--to make sure it remains free 
software for all its users.  We, the Free Software Foundation, use the 
GNU General Public License for most of our software; it applies also to 
any other work released this way by its authors.  You can apply it to 
your programs, too. 

 When we speak of free software, we are referring to freedom, not 
price.  Our General Public Licenses are designed to make sure that you 
have the freedom to distribute copies of free software (and charge for 
them if you wish), that you receive source code or can get it if you 
want it, that you can change the software or use pieces of it in new 
free programs, and that you know you can do these things. 

 To protect your rights, we need to prevent others from denying you 
these rights or asking you to surrender the rights.  Therefore, you have 
certain responsibilities if you distribute copies of the software, or if 
you modify it: responsibilities to respect the freedom of others. 

 For example, if you distribute copies of such a program, whether 
gratis or for a fee, you must pass on to the recipients the same 
freedoms that you received.  You must make sure that they, too, receive 
or can get the source code.  And you must show them these terms so they 
know their rights. 

 Developers that use the GNU GPL protect your rights with two steps: 
(1) assert copyright on the software, and (2) offer you this License 
giving you legal permission to copy, distribute and/or modify it. 

 For the developers' and authors' protection, the GPL clearly explains 
that there is no warranty for this free software.  For both users' and 
authors' sake, the GPL requires that modified versions be marked as 
changed, so that their problems will not be attributed erroneously to 
authors of previous versions. 

 Some devices are designed to deny users access to install or run 
modified versions of the software inside them, although the manufacturer 
can do so.  This is fundamentally incompatible with the aim of 
protecting users' freedom to change the software.  The systematic 
pattern of such abuse occurs in the area of products for individuals to 
use, which is precisely where it is most unacceptable.  Therefore, we 
have designed this version of the GPL to prohibit the practice for those 
products.  If such problems arise substantially in other domains, we 
stand ready to extend this provision to those domains in future versions 
of the GPL, as needed to protect the freedom of users. 

 Finally, every program is threatened constantly by software patents. 
States should not allow patents to restrict development and use of 
software on general-purpose computers, but in those that do, we wish to 
avoid the special danger that patents applied to a free program could 
make it effectively proprietary.  To prevent this, the GPL assures that 
patents cannot be used to render the program non-free. 

 The precise terms and conditions for copying, distribution and 
modification follow. 

                      TERMS AND CONDITIONS 

 0. Definitions. 

 "This License" refers to version 3 of the GNU General Public License. 

 "Copyright" also means copyright-like laws that apply to other kinds of 
works, such as semiconductor masks. 

 "The Program" refers to any copyrightable work licensed under this 
License.  Each licensee is addressed as "you".  "Licensees" and 
"recipients" may be individuals or organizations. 

 To "modify" a work means to copy from or adapt all or part of the work 
in a fashion requiring copyright permission, other than the making of an 
exact copy.  The resulting work is called a "modified version" of the 
earlier work or a work "based on" the earlier work. 

 A "covered work" means either the unmodified Program or a work based 
on the Program. 

 To "propagate" a work means to do anything with it that, without 
permission, would make you directly or secondarily liable for 
infringement under applicable copyright law, except executing it on a 
computer or modifying a private copy.  Propagation includes copying, 
distribution (with or without modification), making available to the 
public, and in some countries other activities as well. 

 To "convey" a work means any kind of propagation that enables other 
parties to make or receive copies.  Mere interaction with a user through 
a computer network, with no transfer of a copy, is not conveying. 

 An interactive user interface displays "Appropriate Legal Notices" 
to the extent that it includes a convenient and prominently visible 
feature that (1) displays an appropriate copyright notice, and (2) 
tells the user that there is no warranty for the work (except to the 
extent that warranties are provided), that licensees may convey the 
work under this License, and how to view a copy of this License.  If 
the interface presents a list of user commands or options, such as a 
menu, a prominent item in the list meets this criterion. 

 1. Source Code. 

 The "source code" for a work means the preferred form of the work 
for making modifications to it.  "Object code" means any non-source 
form of a work. 

 A "Standard Interface" means an interface that either is an official 
standard defined by a recognized standards body, or, in the case of 
interfaces specified for a particular programming language, one that 
is widely used among developers working in that language. 

 The "System Libraries" of an executable work include anything, other 
than the work as a whole, that (a) is included in the normal form of 
packaging a Major Component, but which is not part of that Major 
Component, and (b) serves only to enable use of the work with that 
Major Component, or to implement a Standard Interface for which an 
implementation is available to the public in source code form.  A 
"Major Component", in this context, means a major essential component 
(kernel, window system, and so on) of the specific operating system 
(if any) on which the executable work runs, or a compiler used to 
produce the work, or an object code interpreter used to run it. 

 The "Corresponding Source" for a work in object code form means all 
the source code needed to generate, install, and (for an executable 
work) run the object code and to modify the work, including scripts to 
control those activities.  However, it does not include the work's 
System Libraries, or general-purpose tools or generally available free 
programs which are used unmodified in performing those activities but 
which are not part of the work.  For example, Corresponding Source 
includes interface definition files associated with source files for 
the work, and the source code for shared libraries and dynamically 
linked subprograms that the work is specifically designed to require, 
such as by intimate data communication or control flow between those 
subprograms and other parts of the work. 

 The Corresponding Source need not include anything that users 
can regenerate automatically from other parts of the Corresponding 
Source. 

 The Corresponding Source for a work in source code form is that 
same work. 

 2. Basic Permissions. 

 All rights granted under this License are granted for the term of 
copyright on the Program, and are irrevocable provided the stated 
conditions are met.  This License explicitly affirms your unlimited 
permission to run the unmodified Program.  The output from running a 
covered work is covered by this License only if the output, given its 
content, constitutes a covered work.  This License acknowledges your 
rights of fair use or other equivalent, as provided by copyright law. 

 You may make, run and propagate covered works that you do not 
convey, without conditions so long as your license otherwise remains 
in force.  You may convey covered works to others for the sole purpose 
of having them make modifications exclusively for you, or provide you 
with facilities for running those works, provided that you comply with 
the terms of this License in conveying all material for which you do 
not control copyright.  Those thus making or running the covered works 
for you must do so exclusively on your behalf, under your direction 
and control, on terms that prohibit them from making any copies of 
your copyrighted material outside their relationship with you. 

 Conveying under any other circumstances is permitted solely under 
the conditions stated below.  Sublicensing is not allowed; section 10 
makes it unnecessary. 

 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 

 No covered work shall be deemed part of an effective technological 
measure under any applicable law fulfilling obligations under article 
11 of the WIPO copyright treaty adopted on 20 December 1996, or 
similar laws prohibiting or restricting circumvention of such 
measures. 

 When you convey a covered work, you waive any legal power to forbid 
circumvention of technological measures to the extent such circumvention 
is effected by exercising rights under this License with respect to 
the covered work, and you disclaim any intention to limit operation or 
modification of the work as a means of enforcing, against the work's 
users, your or third parties' legal rights to forbid circumvention of 
technological measures. 

 4. Conveying Verbatim Copies. 

 You may convey verbatim copies of the Program's source code as you 
receive it, in any medium, provided that you conspicuously and 
appropriately publish on each copy an appropriate copyright notice; 
keep intact all notices stating that this License and any 
non-permissive terms added in accord with section 7 apply to the code; 
keep intact all notices of the absence of any warranty; and give all 
recipients a copy of this License along with the Program. 

 You may charge any price or no price for each copy that you convey, 
and you may offer support or warranty protection for a fee. 

 5. Conveying Modified Source Versions. 

 You may convey a work based on the Program, or the modifications to 
produce it from the Program, in the form of source code under the 
terms of section 4, provided that you also meet all of these conditions: 

   a) The work must carry prominent notices stating that you modified 
   it, and giving a relevant date. 

   b) The work must carry prominent notices stating that it is 
   released under this License and any conditions added under section 
   7.  This requirement modifies the requirement in section 4 to 
   "keep intact all notices". 

   c) You must license the entire work, as a whole, under this 
   License to anyone who comes into possession of a copy.  This 
   License will therefore apply, along with any applicable section 7 
   additional terms, to the whole of the work, and all its parts, 
   regardless of how they are packaged.  This License gives no 
   permission to license the work in any other way, but it does not 
   invalidate such permission if you have separately received it. 

   d) If the work has interactive user interfaces, each must display 
   Appropriate Legal Notices; however, if the Program has interactive 
   interfaces that do not display Appropriate Legal Notices, your 
   work need not make them do so. 

 A compilation of a covered work with other separate and independent 
works, which are not by their nature extensions of the covered work, 
and which are not combined with it such as to form a larger program, 
in or on a volume of a storage or distribution medium, is called an 
"aggregate" if the compilation and its resulting copyright are not 
used to limit the access or legal rights of the compilation's users 
beyond what the individual works permit.  Inclusion of a covered work 
in an aggregate does not cause this License to apply to the other 
parts of the aggregate. 

 6. Conveying Non-Source Forms. 

 You may convey a covered work in object code form under the terms 
of sections 4 and 5, provided that you also convey the 
machine-readable Corresponding Source under the terms of this License, 
in one of these ways: 

   a) Convey the object code in, or embodied in, a physical product 
   (including a physical distribution medium), accompanied by the 
   Corresponding Source fixed on a durable physical medium 
   customarily used for software interchange. 

   b) Convey the object code in, or embodied in, a physical product 
   (including a physical distribution medium), accompanied by a 
   written offer, valid for at least three years and valid for as 
   long as you offer spare parts or customer support for that product 
   model, to give anyone who possesses the object code either (1) a 
   copy of the Corresponding Source for all the software in the 
   product that is covered by this License, on a durable physical 
   medium customarily used for software interchange, for a price no 
   more than your reasonable cost of physically performing this 
   conveying of source, or (2) access to copy the 
   Corresponding Source from a network server at no charge. 

   c) Convey individual copies of the object code with a copy of the 
   written offer to provide the Corresponding Source.  This 
   alternative is allowed only occasionally and noncommercially, and 
   only if you received the object code with such an offer, in accord 
   with subsection 6b. 

   d) Convey the object code by offering access from a designated 
   place (gratis or for a charge), and offer equivalent access to the 
   Corresponding Source in the same way through the same place at no 
   further charge.  You need not require recipients to copy the 
   Corresponding Source along with the object code.  If the place to 
   copy the object code is a network server, the Corresponding Source 
   may be on a different server (operated by you or a third party) 
   that supports equivalent copying facilities, provided you maintain 
   clear directions next to the object code saying where to find the 
   Corresponding Source.  Regardless of what server hosts the 
   Corresponding Source, you remain obligated to ensure that it is 
   available for as long as needed to satisfy these requirements. 

   e) Convey the object code using peer-to-peer transmission, provided 
   you inform other peers where the object code and Corresponding 
   Source of the work are being offered to the general public at no 
   charge under subsection 6d. 

 A separable portion of the object code, whose source code is excluded 
from the Corresponding Source as a System Library, need not be 
included in conveying the object code work. 

 A "User Product" is either (1) a "consumer product", which means any 
tangible personal property which is normally used for personal, family, 
or household purposes, or (2) anything designed or sold for incorporation 
into a dwelling.  In determining whether a product is a consumer product, 
doubtful cases shall be resolved in favor of coverage.  For a particular 
product received by a particular user, "normally used" refers to a 
typical or common use of that class of product, regardless of the status 
of the particular user or of the way in which the particular user 
actually uses, or expects or is expected to use, the product.  A product 
is a consumer product regardless of whether the product has substantial 
commercial, industrial or non-consumer uses, unless such uses represent 
the only significant mode of use of the product. 

 "Installation Information" for a User Product means any methods, 
procedures, authorization keys, or other information required to install 
and execute modified versions of a covered work in that User Product from 
a modified version of its Corresponding Source.  The information must 
suffice to ensure that the continued functioning of the modified object 
code is in no case prevented or interfered with solely because 
modification has been made. 

 If you convey an object code work under this section in, or with, or 
specifically for use in, a User Product, and the conveying occurs as 
part of a transaction in which the right of possession and use of the 
User Product is transferred to the recipient in perpetuity or for a 
fixed term (regardless of how the transaction is characterized), the 
Corresponding Source conveyed under this section must be accompanied 
by the Installation Information.  But this requirement does not apply 
if neither you nor any third party retains the ability to install 
modified object code on the User Product (for example, the work has 
been installed in ROM). 

 The requirement to provide Installation Information does not include a 
requirement to continue to provide support service, warranty, or updates 
for a work that has been modified or installed by the recipient, or for 
the User Product in which it has been modified or installed.  Access to a 
network may be denied when the modification itself materially and 
adversely affects the operation of the network or violates the rules and 
protocols for communication across the network. 

 Corresponding Source conveyed, and Installation Information provided, 
in accord with this section must be in a format that is publicly 
documented (and with an implementation available to the public in 
source code form), and must require no special password or key for 
unpacking, reading or copying. 

 7. Additional Terms. 

 "Additional permissions" are terms that supplement the terms of this 
License by making exceptions from one or more of its conditions. 
Additional permissions that are applicable to the entire Program shall 
be treated as though they were included in this License, to the extent 
that they are valid under applicable law.  If additional permissions 
apply only to part of the Program, that part may be used separately 
under those permissions, but the entire Program remains governed by 
this License without regard to the additional permissions. 

 When you convey a copy of a covered work, you may at your option 
remove any additional permissions from that copy, or from any part of 
it.  (Additional permissions may be written to require their own 
removal in certain cases when you modify the work.)  You may place 
additional permissions on material, added by you to a covered work, 
for which you have or can give appropriate copyright permission. 

 Notwithstanding any other provision of this License, for material you 
add to a covered work, you may (if authorized by the copyright holders of 
that material) supplement the terms of this License with terms: 

   a) Disclaiming warranty or limiting liability differently from the 
   terms of sections 15 and 16 of this License; or 

   b) Requiring preservation of specified reasonable legal notices or 
   author attributions in that material or in the Appropriate Legal 
   Notices displayed by works containing it; or 

   c) Prohibiting misrepresentation of the origin of that material, or 
   requiring that modified versions of such material be marked in 
   reasonable ways as different from the original version; or 

   d) Limiting the use for publicity purposes of names of licensors or 
   authors of the material; or 

   e) Declining to grant rights under trademark law for use of some 
   trade names, trademarks, or service marks; or 

   f) Requiring indemnification of licensors and authors of that 
   material by anyone who conveys the material (or modified versions of 
   it) with contractual assumptions of liability to the recipient, for 
   any liability that these contractual assumptions directly impose on 
   those licensors and authors. 

 All other non-permissive additional terms are considered "further 
restrictions" within the meaning of section 10.  If the Program as you 
received it, or any part of it, contains a notice stating that it is 
governed by this License along with a term that is a further 
restriction, you may remove that term.  If a license document contains 
a further restriction but permits relicensing or conveying under this 
License, you may add to a covered work material governed by the terms 
of that license document, provided that the further restriction does 
not survive such relicensing or conveying. 

 If you add terms to a covered work in accord with this section, you 
must place, in the relevant source files, a statement of the 
additional terms that apply to those files, or a notice indicating 
where to find the applicable terms. 

 Additional terms, permissive or non-permissive, may be stated in the 
form of a separately written license, or stated as exceptions; 
the above requirements apply either way. 

 8. Termination. 

 You may not propagate or modify a covered work except as expressly 
provided under this License.  Any attempt otherwise to propagate or 
modify it is void, and will automatically terminate your rights under 
this License (including any patent licenses granted under the third 
paragraph of section 11). 

 However, if you cease all violation of this License, then your 
license from a particular copyright holder is reinstated (a) 
provisionally, unless and until the copyright holder explicitly and 
finally terminates your license, and (b) permanently, if the copyright 
holder fails to notify you of the violation by some reasonable means 
prior to 60 days after the cessation. 

 Moreover, your license from a particular copyright holder is 
reinstated permanently if the copyright holder notifies you of the 
violation by some reasonable means, this is the first time you have 
received notice of violation of this License (for any work) from that 
copyright holder, and you cure the violation prior to 30 days after 
your receipt of the notice. 

 Termination of your rights under this section does not terminate the 
licenses of parties who have received copies or rights from you under 
this License.  If your rights have been terminated and not permanently 
reinstated, you do not qualify to receive new licenses for the same 
material under section 10. 

 9. Acceptance Not Required for Having Copies. 

 You are not required to accept this License in order to receive or 
run a copy of the Program.  Ancillary propagation of a covered work 
occurring solely as a consequence of using peer-to-peer transmission 
to receive a copy likewise does not require acceptance.  However, 
nothing other than this License grants you permission to propagate or 
modify any covered work.  These actions infringe copyright if you do 
not accept this License.  Therefore, by modifying or propagating a 
covered work, you indicate your acceptance of this License to do so. 

 10. Automatic Licensing of Downstream Recipients. 

 Each time you convey a covered work, the recipient automatically 
receives a license from the original licensors, to run, modify and 
propagate that work, subject to this License.  You are not responsible 
for enforcing compliance by third parties with this License. 

 An "entity transaction" is a transaction transferring control of an 
organization, or substantially all assets of one, or subdividing an 
organization, or merging organizations.  If propagation of a covered 
work results from an entity transaction, each party to that 
transaction who receives a copy of the work also receives whatever 
licenses to the work the party's predecessor in interest had or could 
give under the previous paragraph, plus a right to possession of the 
Corresponding Source of the work from the predecessor in interest, if 
the predecessor has it or can get it with reasonable efforts. 

 You may not impose any further restrictions on the exercise of the 
rights granted or affirmed under this License.  For example, you may 
not impose a license fee, royalty, or other charge for exercise of 
rights granted under this License, and you may not initiate litigation 
(including a cross-claim or counterclaim in a lawsuit) alleging that 
any patent claim is infringed by making, using, selling, offering for 
sale, or importing the Program or any portion of it. 

 11. Patents. 

 A "contributor" is a copyright holder who authorizes use under this 
License of the Program or a work on which the Program is based.  The 
work thus licensed is called the contributor's "contributor version". 

 A contributor's "essential patent claims" are all patent claims 
owned or controlled by the contributor, whether already acquired or 
hereafter acquired, that would be infringed by some manner, permitted 
by this License, of making, using, or selling its contributor version, 
but do not include claims that would be infringed only as a 
consequence of further modification of the contributor version.  For 
purposes of this definition, "control" includes the right to grant 
patent sublicenses in a manner consistent with the requirements of 
this License. 

 Each contributor grants you a non-exclusive, worldwide, royalty-free 
patent license under the contributor's essential patent claims, to 
make, use, sell, offer for sale, import and otherwise run, modify and 
propagate the contents of its contributor version. 

 In the following three paragraphs, a "patent license" is any express 
agreement or commitment, however denominated, not to enforce a patent 
(such as an express permission to practice a patent or covenant not to 
sue for patent infringement).  To "grant" such a patent license to a 
party means to make such an agreement or commitment not to enforce a 
patent against the party. 

 If you convey a covered work, knowingly relying on a patent license, 
and the Corresponding Source of the work is not available for anyone 
to copy, free of charge and under the terms of this License, through a 
publicly available network server or other readily accessible means, 
then you must either (1) cause the Corresponding Source to be so 
available, or (2) arrange to deprive yourself of the benefit of the 
patent license for this particular work, or (3) arrange, in a manner 
consistent with the requirements of this License, to extend the patent 
license to downstream recipients.  "Knowingly relying" means you have 
actual knowledge that, but for the patent license, your conveying the 
covered work in a country, or your recipient's use of the covered work 
in a country, would infringe one or more identifiable patents in that 
country that you have reason to believe are valid. 

 If, pursuant to or in connection with a single transaction or 
arrangement, you convey, or propagate by procuring conveyance of, a 
covered work, and grant a patent license to some of the parties 
receiving the covered work authorizing them to use, propagate, modify 
or convey a specific copy of the covered work, then the patent license 
you grant is automatically extended to all recipients of the covered 
work and works based on it. 

 A patent license is "discriminatory" if it does not include within 
the scope of its coverage, prohibits the exercise of, or is 
conditioned on the non-exercise of one or more of the rights that are 
specifically granted under this License.  You may not convey a covered 
work if you are a party to an arrangement with a third party that is 
in the business of distributing software, under which you make payment 
to the third party based on the extent of your activity of conveying 
the work, and under which the third party grants, to any of the 
parties who would receive the covered work from you, a discriminatory 
patent license (a) in connection with copies of the covered work 
conveyed by you (or copies made from those copies), or (b) primarily 
for and in connection with specific products or compilations that 
contain the covered work, unless you entered into that arrangement, 
or that patent license was granted, prior to 28 March 2007. 

 Nothing in this License shall be construed as excluding or limiting 
any implied license or other defenses to infringement that may 
otherwise be available to you under applicable patent law. 

 12. No Surrender of Others' Freedom. 

 If conditions are imposed on you (whether by court order, agreement or 
otherwise) that contradict the conditions of this License, they do not 
excuse you from the conditions of this License.  If you cannot convey a 
covered work so as to satisfy simultaneously your obligations under this 
License and any other pertinent obligations, then as a consequence you may 
not convey it at all.  For example, if you agree to terms that obligate you 
to collect a royalty for further conveying from those to whom you convey 
the Program, the only way you could satisfy both those terms and this 
License would be to refrain entirely from conveying the Program. 

 13. Use with the GNU Affero General Public License. 

 Notwithstanding any other provision of this License, you have 
permission to link or combine any covered work with a work licensed 
under version 3 of the GNU Affero General Public License into a single 
combined work, and to convey the resulting work.  The terms of this 
License will continue to apply to the part which is the covered work, 
but the special requirements of the GNU Affero General Public License, 
section 13, concerning interaction through a network will apply to the 
combination as such. 

 14. Revised Versions of this License. 

 The Free Software Foundation may publish revised and/or new versions of 
the GNU General Public License from time to time.  Such new versions will 
be similar in spirit to the present version, but may differ in detail to 
address new problems or concerns. 

 Each version is given a distinguishing version number.  If the 
Program specifies that a certain numbered version of the GNU General 
Public License "or any later version" applies to it, you have the 
option of following the terms and conditions either of that numbered 
version or of any later version published by the Free Software 
Foundation.  If the Program does not specify a version number of the 
GNU General Public License, you may choose any version ever published 
by the Free Software Foundation. 

 If the Program specifies that a proxy can decide which future 
versions of the GNU General Public License can be used, that proxy's 
public statement of acceptance of a version permanently authorizes you 
to choose that version for the Program. 

 Later license versions may give you additional or different 
permissions.  However, no additional obligations are imposed on any 
author or copyright holder as a result of your choosing to follow a 
later version. 

 15. Disclaimer of Warranty. 

 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 
APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 
OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 
PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 
IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 
ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 

 16. Limitation of Liability. 

 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 
USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 
DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 
EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 
SUCH DAMAGES. 

 17. Interpretation of Sections 15 and 16. 

 If the disclaimer of warranty and limitation of liability provided 
above cannot be given local legal effect according to their terms, 
reviewing courts shall apply local law that most closely approximates 
an absolute waiver of all civil liability in connection with the 
Program, unless a warranty or assumption of liability accompanies a 
copy of the Program in return for a fee. 

                    END OF TERMS AND CONDITIONS 

           How to Apply These Terms to Your New Programs 

 If you develop a new program, and you want it to be of the greatest 
possible use to the public, the best way to achieve this is to make it 
free software which everyone can redistribute and change under these terms. 

 To do so, attach the following notices to the program.  It is safest 
to attach them to the start of each source file to most effectively 
state the exclusion of warranty; and each file should have at least 
the "copyright" line and a pointer to where the full notice is found. 

   <one line to give the program's name and a brief idea of what it does.> 
   Copyright (C) <year>  <name of author> 

   This program is free software: you can redistribute it and/or modify 
   it under the terms of the GNU General Public License as published by 
   the Free Software Foundation, either version 3 of the License, or 
   (at your option) any later version. 

   This program is distributed in the hope that it will be useful, 
   but WITHOUT ANY WARRANTY; without even the implied warranty of 
   MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the 
   GNU General Public License for more details. 

   You should have received a copy of the GNU General Public License 
   along with this program.  If not, see <http://www.gnu.org/licenses/>. 

Also add information on how to contact you by electronic and paper mail. 

 If the program does terminal interaction, make it output a short 
notice like this when it starts in an interactive mode: 

   <program>  Copyright (C) <year>  <name of author> 
   This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. 
   This is free software, and you are welcome to redistribute it 
   under certain conditions; type `show c' for details. 

The hypothetical commands `show w' and `show c' should show the appropriate 
parts of the General Public License.  Of course, your program's commands 
might be different; for a GUI interface, you would use an "about box". 

 You should also get your employer (if you work as a programmer) or school, 
if any, to sign a "copyright disclaimer" for the program, if necessary. 
For more information on this, and how to apply and follow the GNU GPL, see 
<http://www.gnu.org/licenses/>. 

 The GNU General Public License does not permit incorporating your program 
into proprietary programs.  If your program is a subroutine library, you 
may consider it more useful to permit linking proprietary applications with 
the library.  If this is what you want to do, use the GNU Lesser General 
Public License instead of this License.  But first, please read

                  GNU LESSER GENERAL PUBLIC LICENSE 
                      Version 3, 29 June 2007 

Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 
Everyone is permitted to copy and distribute verbatim copies 
of this license document, but changing it is not allowed. 


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

 0. Additional Definitions. 

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

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

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

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

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

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

 1. Exception to Section 3 of the GNU GPL. 

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

 2. Conveying Modified Versions. 

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

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

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

 3. Object Code Incorporating Material from Library Header Files. 

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

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

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

 4. Combined Works. 

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

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

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

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

  d) Do one of the following: 

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

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

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

 5. Combined Libraries. 

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

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

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

 6. Revised Versions of the GNU Lesser General Public License. 

 The Free Software Foundation may publish revised and/or new versions 
of the GNU Lesser General Public License from time to time. Such new 
versions will be similar in spirit to the present version, but may 
differ in detail to address new problems or concerns. 

 Each version is given a distinguishing version number. If the 
Library as you received it specifies that a certain numbered version 
of the GNU Lesser General Public License "or any later version" 
applies to it, you have the option of following the terms and 
conditions either of that published version or of any later version 
published by the Free Software Foundation. If the Library as you 
received it does not specify a version number of the GNU Lesser 
General Public License, you may choose any version of the GNU Lesser 
General Public License ever published by the Free Software Foundation. 

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