 +====== ​ GNU Free Documentation License ======
 +<​code> ​                 GNU Free Documentation License
 +                    Version 1.2, November 2002
  
 +
 + ​Copyright (C) 2000,​2001,​2002 ​ Free Software Foundation, Inc.
 +     51 Franklin St, Fifth Floor, Boston, MA  02110-1301 ​ USA
 + ​Everyone is permitted to copy and distribute verbatim copies
 + of this license document, but changing it is not allowed.
 +
 +
 +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.
 +
 +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 for under this License. ​ Any other attempt to
 +copy, modify, sublicense or distribute the Document is void, and will
 +automatically terminate your rights under this License. ​ However,
 +parties who have received copies, or rights, from you under this
 +License will not have their licenses terminated so long as such
 +parties remain in full compliance.
 +
 +
 +10. FUTURE REVISIONS OF THIS LICENSE
 +
 +The Free Software Foundation may publish new, revised versions
 +of the GNU Free Documentation License from time to time.  Such new
 +versions will be similar in spirit to the present version, but may
 +differ in detail to address new problems or concerns. ​ See
 +http://​www.gnu.org/​copyleft/​.
 +
 +Each version of the License is given a distinguishing version number.
 +If the Document specifies that a particular numbered version of this
 +License "or any later version"​ applies to it, you have the option of
 +following the terms and conditions either of that specified version or
 +of any later version that has been published (not as a draft) by the
 +Free Software Foundation. ​ If the Document does not specify a version
 +number of this License, you may choose any version ever published (not
 +as a draft) by the Free Software Foundation.
 +
 +
 +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 1.2
 +    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.
