Everyone is permitted to copy and distribute verbatim copies

         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
         
      
      
      
         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
         
      
      
      
         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
         
      
      
      
         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
         
      
      
      
         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
         
      
      
      
         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
         
      
      
      
         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
         
      
      
      
         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
         
      
      
      
         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
         
      
      
      
         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
         
      
      
      
         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
