+ Version 1.3, 3 November 2008
+
+
+ Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation, Inc.
+
+ 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
+https://www.gnu.org/licenses/.
+
+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.

- 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:
-
- #+attr_texinfo: :enum A
- 1. 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.
-
- 2. 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.
-
- 3. State on the Title page the name of the publisher of the
- Modified Version, as the publisher.
-
- 4. Preserve all the copyright notices of the Document.
-
- 5. Add an appropriate copyright notice for your modifications
- adjacent to the other copyright notices.
-
- 6. 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.
-
- 7. Preserve in that license notice the full lists of Invariant
- Sections and required Cover Texts given in the Document's
- license notice.
-
- 8. Include an unaltered copy of this License.
-
- 9. 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.
-
- 10. 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.
-
- 11. 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.
-
- 12. 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.
-
- 13. Delete any section Entitled "Endorsements". Such a section may
- not be included in the Modified Version.
-
- 14. Do not retitle any existing section to be Entitled
- "Endorsements" or to conflict in title with any Invariant
- Section.
-
- 15. 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
- https://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.

-*Preamble*
-#+end_center
-
-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.
-
-#+begin_center
-*TERMS AND CONDITIONS*
-#+end_center
-
-0. [@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. [@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. [@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. [@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. [@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. [@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:
-
- 1) [@1] The work must carry prominent notices stating that you modified it,
- and giving a relevant date.
-
- 2) [@2] 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".
-
- 3) [@3] 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.
-
- 4) [@4] 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. [@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:
-
- 1) [@1] 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.
-
- 2) [@2] 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.
-
- 3) [@3] 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.
-
- 4) [@4] 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.
-
- 5) [@5] 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. [@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:
-
- 1) [@a] Disclaiming warranty or limiting liability differently from the
- terms of sections 15 and 16 of this License; or
-
- 2) [@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
-
- 3) [@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
-
- 4) [@d] Limiting the use for publicity purposes of names of licensors
- or authors of the material; or
-
- 5) [@e] Declining to grant rights under trademark law for use of some
- trade names, trademarks, or service marks; or
-
- 6) [@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. [@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. [@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. [@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. [@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. [@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. [@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. [@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. [@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. [@15] *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. [@16] *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.

-** How to Apply These Terms to Your New Programs
-:PROPERTIES:
-:CUSTOM_ID: how-to-apply-these-terms-to-your-new-programs
-:END:
-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.
-
-#+begin_example
-
- Copyright (C)
-
- 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 .
-#+end_example
-
-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:
-
-#+begin_example
- Copyright (C)
- 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.
-#+end_example
-
-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 [[https://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 [[https://www.gnu.org/licenses/why-not-lgpl.html]].

+ GNU GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc.
+ 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.
+
+
+ Copyright (C)
+
+ 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 .
+
+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:
+
+ Copyright (C)
+ 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
+.
+
+ 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
+.
