******************************

     GNU Free Documentation License
     
     Version 1.1, March 2000
     
     Copyright (C) 2000  Free Software Foundation, Inc.
     59 Temple Place, Suite 330, Boston, MA  02111-1307  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.
     
     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.
