| GNU Free Documentation License
 | |
| 
 | |
| Version 1.1, March 2000
 | |
| 
 | |
| Copyright (C) 2000 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 written
 | |
| 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 that contains a notice placed
 | |
| by the copyright holder saying it can be distributed under the terms of this
 | |
| License. The "Document", below, refers to any such manual or work. Any member
 | |
| of the public is a licensee, and is addressed as "you".
 | |
| 
 | |
| 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.
 | |
| (For example, 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.
 | |
| 
 | |
| 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 "Transparent" copy of the Document means a machine-readable copy, represented
 | |
| in a format whose specification is available to the general public, whose
 | |
| contents can be viewed and edited directly and 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 has been designed to thwart or discourage
 | |
| subsequent modification by readers is not Transparent. 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 designed for human modification.
 | |
| Opaque formats include PostScript, PDF, 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 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.
 | |
| 
 | |
|    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 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 publicly-accessible
 | |
| computer-network location containing a complete Transparent copy of the Document,
 | |
| free of added material, which the general network-using public has access
 | |
| to download anonymously at no charge using public-standard network protocols.
 | |
| 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 less than five).
 | |
| 
 | |
| 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", and 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. In any section entitled "Acknowledgements" or "Dedications", preserve the
 | |
| section's title, 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 as "Endorsements" or to conflict in
 | |
| title with any Invariant Section.
 | |
| 
 | |
| 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.
 | |
| 
 | |
| 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,
 | |
| does not as a whole count as a Modified Version of the Document, provided
 | |
| no compilation copyright is claimed for the compilation. Such a compilation
 | |
| is called an "aggregate", and this License does not apply to the other self-contained
 | |
| works thus compiled with the Document, on account of their being thus compiled,
 | |
| if they 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 quarter of the entire
 | |
| aggregate, the Document's Cover Texts may be placed on covers that surround
 | |
| only the Document within the aggregate. Otherwise they must appear on covers
 | |
| around 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 provided that you also include the original English version
 | |
| of this License. In case of a disagreement between the translation and the
 | |
| original English version of this License, the original English version will
 | |
| prevail.
 | |
| 
 | |
|    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 1.1 or any later version published by the Free Software Foundation;
 | |
| with the Invariant Sections being LIST THEIR TITLES, with the Front-Cover
 | |
| Texts being LIST, and with the Back-Cover Texts being LIST. A copy of the
 | |
| license is included in the section entitled "GNU Free Documentation License".
 | |
| 
 | |
| If you have no Invariant Sections, write "with no Invariant Sections" instead
 | |
| of saying which ones are invariant. If you have no Front-Cover Texts, write
 | |
| "no Front-Cover Texts" instead of "Front-Cover Texts being LIST"; likewise
 | |
| for Back-Cover Texts.
 | |
| 
 | |
| 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.
 |
