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.
