-slib3a3 news:
-
-Multi-dimensional linear interpolation and resampling of arrays are

-with implementations which are case-sensitive when reading symbols.
-
- * grapheps.scm (graph:plot): Plot multiple traces from array.
- (functions->array): Generalizes graph:plot-function.
-
- * root.scm (integer-sqrt): Changed to algorithm attributed to
- Bradley Lucier by Steve VanDevender.
- * slib.texi (Root Finding): integer-sqrt changed to floor of sqrt.
-
- * linterp.scm (interpolate-array-ref, resample-array!): Added.
-
- * bytenumb.scm (bytes->ieee-float, bytes->ieee-double)

- Downcased *slib-version* symbol.
-
- * top-refs.scm (top-refs:expression): Check for lists before
- walking CASE and COND clauses (srfi-61.scm macro broke it).
-
- * http-cgi.scm (query-alist->parameter-list): Fixed order of nary
- fields.
- * http-cgi.scm (http:status-line): Changed to HTTP-1.0; works
- better in MS-Windows.

+@item
+PREAMBLE
+
+The purpose of this License is to make a manual, textbook, or other
+functional and useful document @dfn{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.
+
+@item
+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
+@sc{ascii} without markup, Texinfo input format, La@TeX{} input
+format, @acronym{SGML} or @acronym{XML} using a publicly available
+@acronym{DTD}, and standard-conforming simple @acronym{HTML},
+PostScript or @acronym{PDF} designed for human modification. Examples
+of transparent image formats include @acronym{PNG}, @acronym{XCF} and
+@acronym{JPG}. Opaque formats include proprietary formats that can be
+read and edited only by proprietary word processors, @acronym{SGML} or
+@acronym{XML} for which the @acronym{DTD} and/or processing tools are
+not generally available, and the machine-generated @acronym{HTML},
+PostScript or @acronym{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.
+
+@item
+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.
+
+@item
+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.
+
+@item
+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:
+
+@enumerate A
+@item
+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.
+
+@item
+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.
+
+@item
+State on the Title page the name of the publisher of the
+Modified Version, as the publisher.
+
+@item
+Preserve all the copyright notices of the Document.
+
+@item
+Add an appropriate copyright notice for your modifications
+adjacent to the other copyright notices.
+
+@item
+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.
+
+@item
+Preserve in that license notice the full lists of Invariant Sections
+and required Cover Texts given in the Document's license notice.
+
+@item
+Include an unaltered copy of this License.
+
+@item
+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.
+
+@item
+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.
+
+@item
+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.
+
+@item
+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.
+
+@item
+Delete any section Entitled ``Endorsements''. Such a section
+may not be included in the Modified Version.
+
+@item
+Do not retitle any existing section to be Entitled ``Endorsements'' or
+to conflict in title with any Invariant Section.
+
+@item
+Preserve any Warranty Disclaimers.
+@end enumerate
+
+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.
+
+@item
+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.''
+
+@item
+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.
+
+@item
+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.
+
+@item
+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.
+
+@item
+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.
+
+@item
+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
+@uref{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.

+
+@node How to use this License for your documents, , Copying This Manual, About this manual
+@subsection 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:
+
+@smallexample
+@group
+ Copyright (C) @var{year} @var{your name}.
+ Permission is granted to copy, distribute and/or modify this document
+ under the terms of the GNU Free Documentation License, Version 1.2
+ 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''.
+@end group
+@end smallexample
+
+If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
+replace the ``with...Texts.'' line with this:
+
+@smallexample
+@group
+ with the Invariant Sections being @var{list their titles}, with
+ the Front-Cover Texts being @var{list}, and with the Back-Cover Texts
+ being @var{list}.
+@end group
+@end smallexample
+
+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.

+8.6.1 Copying This Manual |
+------------------------- |
+ |
+ Version 1.2, November 2002 |
+ |
+ Copyright (C) 2000,2001,2002 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 |
+ 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. |

+8.6.2 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 1.2 |
+ 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. |
