 After filling an empty stomach for some while, Sheiny couldn't help but visit ideas of helping her mother to gain a few bucks. But the frustration of Sheiny about the world grew even more when she realized that there was nothing legal that she could do to help. She was trying to convince the mother about a few ideas. But mother felt those ideas to be too clever for her liking. And said something stupid like "You're just a child" to Sheiny on each such offering. 
 
-Without the mother there was an obvious and only choice to sell lemonade. A very good way to make enough money for a whole another lemon. She tried selling other things, like candy and chocolate bars. Adding a bit to their price to gain a little, but this was unsuccessful. Kids didn't want to spend more of their lunch money then necessary. And they could buy the same items for cheaper in the school's cafeteria. She sold one chocolate bar to Brandy. But he was ridiculed for that by other children. So she could not sell to him anymore.

But he was ridiculed for that by other children. So she could not sell to him anymore.
 
 Sheiny realized that her inability to make legal money only meant one thing. She had to make the money somehow illegally. Going to work was illegal enough, but since directors of businesses didn't want problems with the law themselves, they all would've denied her. Selling weapons was not possible because of how would have she obtained them in the first place. Selling drugs was more possible, but there was a competition with Richie and his gang that were already doing it in the school and they were also carrying knives. She didn't have anything to sell, legal or illegal, until she realized something. She is a 9 years old girl with a camera in her pocket. She can try and produce something to sell.

 Afterwards she asked Mr. Hambleton to chat a little after school. He was nervous about it, but still waited her after the school ended. She took him away from the school into a place where there is not too many people. And there they spoke about what kind of images excite him. She didn't simply want to get money from him. It was not interesting. Too stupid. Her mother would've done that. But Sheiny is instead doing a rather interesting research project. She is trying to answer whether she could produce stuff that people gonna pay for. She already knew his budget, she just needed to know what he would pay for. Mr. Hambleton could not believe what he was hearing. It was too good to be true. She found out about his secret thoughts and didn't just want to take advantage from it. She wanted to make an offering to him. To which he felt morally obligated to agree. 
 
-So the deal was done. She would produce some of the illegal stuff for him in exchange for money. And that's how Sheiny did her first real sell. But she didn't stop there. She wanted to learn more about this. For example, the image that she found on his computer should have been gotten there in some way. Is there a competition? How do they spread their stuff? What is the quality of their stuff? How can she produce better stuff? How can she sell more? These were the question on her mind now.

-1. Definitions.
+Version 1.3, 3 November 2008
 
-"License" shall mean the terms and conditions for use, reproduction, and distribution as defined by Sections 1 through 9 of this document.
+Copyright (C) 2000, 2001, 2002, 2007, 2008 Free Software Foundation,

-"Licensor" shall mean the copyright owner or entity authorized by the copyright owner that is granting the License.
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
 
-"Legal Entity" shall mean the union of the acting entity and all other entities that control, are controlled by, or are under common control with that entity. For the purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity.
+#### 0. PREAMBLE
 
-"You" (or "Your") shall mean an individual or Legal Entity exercising permissions granted by this License.
+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.
 
-"Source" form shall mean the preferred form for making modifications, including but not limited to software source code, documentation source, and configuration files.
+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.
 
-"Object" form shall mean any form resulting from mechanical transformation or translation of a Source form, including but not limited to compiled object code, generated documentation, and conversions to other media types.
+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.
 
-"Work" shall mean the work of authorship, whether in Source or Object form, made available under the License, as indicated by a copyright notice that is included in or attached to the work (an example is provided in the Appendix below).
+#### 1. APPLICABILITY AND DEFINITIONS
 
-"Derivative Works" shall mean any work, whether in Source or Object form, that is based on (or derived from) the Work and for which the editorial revisions, annotations, elaborations, or other modifications represent, as a whole, an original work of authorship. For the purposes of this License, Derivative Works shall not include works that remain separable from, or merely link (or bind by name) to the interfaces of, the Work and Derivative Works thereof.
+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.
 
-"Contribution" shall mean any work of authorship, including the original version of the Work and any modifications or additions to that Work or Derivative Works thereof, that is intentionally submitted to Licensor for inclusion in the Work by the copyright owner or by an individual or Legal Entity authorized to submit on behalf of the copyright owner. For the purposes of this definition, "submitted" means any form of electronic, verbal, or written communication sent to the Licensor or its representatives, including but not limited to communication on electronic mailing lists, source code control systems, and issue tracking systems that are managed by, or on behalf of, the Licensor for the purpose of discussing and improving the Work, but excluding communication that is conspicuously marked or otherwise designated in writing by the copyright owner as "Not a Contribution."
+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.
 
-"Contributor" shall mean Licensor and any individual or Legal Entity on behalf of whom a Contribution has been received by Licensor and subsequently incorporated within the Work.
+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.
 
-2. Grant of Copyright License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable copyright license to reproduce, prepare Derivative Works of, publicly display, publicly perform, sublicense, and distribute the Work and such Derivative Works in Source or Object form.
+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.
 
-3. Grant of Patent License. Subject to the terms and conditions of this License, each Contributor hereby grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free, irrevocable (except as stated in this section) patent license to make, have made, use, offer to sell, sell, import, and otherwise transfer the Work, where such license applies only to those patent claims licensable by such Contributor that are necessarily infringed by their Contribution(s) alone or by combination of their Contribution(s) with the Work to which such Contribution(s) was submitted. If You institute patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Work or a Contribution incorporated within the Work constitutes direct or contributory patent infringement, then any patent licenses granted to You under this License for that Work shall terminate as of the date such litigation is filed.
+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.
 
-4. Redistribution. You may reproduce and distribute copies of the Work or Derivative Works thereof in any medium, with or without modifications, and in Source or Object form, provided that You meet the following conditions:
+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".
 
-(a) You must give any other recipients of the Work or Derivative Works a copy of this License; and
+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.
 
-(b) You must cause any modified files to carry prominent notices stating that You changed the files; and
+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.
 
-(c) You must retain, in the Source form of any Derivative Works that You distribute, all copyright, patent, trademark, and attribution notices from the Source form of the Work, excluding those notices that do not pertain to any part of the Derivative Works; and
+The "publisher" means any person or entity that distributes copies of
+the Document to the public.
 
-(d) If the Work includes a "NOTICE" text file as part of its distribution, then any Derivative Works that You distribute must include a readable copy of the attribution notices contained within such NOTICE file, excluding those notices that do not pertain to any part of the Derivative Works, in at least one of the following places: within a NOTICE text file distributed as part of the Derivative Works; within the Source form or documentation, if provided along with the Derivative Works; or, within a display generated by the Derivative Works, if and wherever such third-party notices normally appear. The contents of the NOTICE file are for informational purposes only and do not modify the License. You may add Your own attribution notices within Derivative Works that You distribute, alongside or as an addendum to the NOTICE text from the Work, provided that such additional attribution notices cannot be construed as modifying the License.
+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.
 
-You may add Your own copyright statement to Your modifications and may provide additional or different license terms and conditions for use, reproduction, or distribution of Your modifications, or for any such Derivative Works as a whole, provided Your use, reproduction, and distribution of the Work otherwise complies with the conditions stated in this License.
+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.
 
-5. Submission of Contributions. Unless You explicitly state otherwise, any Contribution intentionally submitted for inclusion in the Work by You to the Licensor shall be under the terms and conditions of this License, without any additional terms or conditions. Notwithstanding the above, nothing herein shall supersede or modify the terms of any separate license agreement you may have executed with Licensor regarding such Contributions.
+#### 2. VERBATIM COPYING
 
-6. Trademarks. This License does not grant permission to use the trade names, trademarks, service marks, or product names of the Licensor, except as required for reasonable and customary use in describing the origin of the Work and reproducing the content of the NOTICE file.
+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.
 
-7. Disclaimer of Warranty. Unless required by applicable law or agreed to in writing, Licensor provides the Work (and each Contributor provides its Contributions) on an "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied, including, without limitation, any warranties or conditions of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are solely responsible for determining the appropriateness of using or redistributing the Work and assume any risks associated with Your exercise of permissions under this License.
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
 
-8. Limitation of Liability. In no event and under no legal theory, whether in tort (including negligence), contract, or otherwise, unless required by applicable law (such as deliberate and grossly negligent acts) or agreed to in writing, shall any Contributor be liable to You for damages, including any direct, indirect, special, incidental, or consequential damages of any character arising as a result of this License or out of the use or inability to use the Work (including but not limited to damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses), even if such Contributor has been advised of the possibility of such damages.
+#### 3. COPYING IN QUANTITY
 
-9. Accepting Warranty or Additional Liability. While redistributing the Work or Derivative Works thereof, You may choose to offer, and charge a fee for, acceptance of support, warranty, indemnity, or other liability obligations and/or rights consistent with this License. However, in accepting such obligations, You may act only on Your own behalf and on Your sole responsibility, not on behalf of any other Contributor, and only if You agree to indemnify, defend, and hold each Contributor harmless for any liability incurred by, or claims asserted against, such Contributor by reason of your accepting any such warranty or additional liability.
+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.
 
-END OF TERMS AND CONDITIONS
+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.
 
-APPENDIX: How to apply the Apache License to your work.
+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.
 
-To apply the Apache License to your work, attach the following boilerplate notice, with the fields enclosed by brackets "[]" replaced with your own identifying information. (Don't include the brackets!) The text should be enclosed in the appropriate comment syntax for the file format. We also recommend that a file or class name and description of purpose be included on the same "printed page" as the copyright notice for easier identification within third-party archives.
+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
 
-Licensed under the Apache License, Version 2.0 (the "License"); 
-you may not use this file except in compliance with the License. 
-You may obtain a copy of the License at
+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:
 
-http://www.apache.org/licenses/LICENSE-2.0
+-   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.
 
-Unless required by applicable law or agreed to in writing, software 
-distributed under the License is distributed on an "AS IS" BASIS, 
-WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 
-See the License for the specific language governing permissions and 
-limitations under the License.
+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.
