127          modify, display, perform, sublicense and distribute the Original

129          as part of a Larger Work; and
130
131          (b) under Patents Claims infringed by the making, using or

135
136          (c) the licenses granted in this Section 2.1(a) and (b) are
137          effective on the date Initial Developer first distributes
138          Original Code under the terms of this License.
139
140          (d) Notwithstanding Section 2.1(b) above, no patent license is
141          granted: 1) for code that You delete from the Original Code; 2)

147     Subject to third party intellectual property claims, each Contributor
148     hereby grants You a world-wide, royalty-free, non-exclusive license
149
150          (a)  under intellectual property rights (other than patent or
151          trademark) Licensable by Contributor, to use, reproduce, modify,
152          display, perform, sublicense and distribute the Modifications

155          and/or as part of a Larger Work; and
156
157          (b) under Patent Claims infringed by the making, using, or
158          selling of  Modifications made by that Contributor either alone

165
166          (c) the licenses granted in Sections 2.2(a) and 2.2(b) are
167          effective on the date Contributor first makes Commercial Use of
168          the Covered Code.

176          Contributor Version) or other devices; or 4) under Patent Claims
177          infringed by Covered Code in the absence of Modifications made by
178          that Contributor.
179
1803. Distribution Obligations.
181
182     3.1. Application of License.
183     The Modifications which You create or to which You contribute are
184     governed by the terms of this License, including without limitation
185     Section 2.2. The Source Code version of Covered Code may be
186     distributed only under the terms of this License or a future version
187     of this License released under Section 6.1, and You must include a
188     copy of this License with every copy of the Source Code You
189     distribute. You may not offer or impose any terms on any Source Code
190     version that alters or restricts the applicable version of this
191     License or the recipients' rights hereunder. However, You may include
192     an additional document offering the additional rights described in
193     Section 3.5.
194
195     3.2. Availability of Source Code.
196     Any Modification which You create or to which You contribute must be
197     made available in Source Code form under the terms of this License
198     either on the same media as an Executable version or via an accepted
199     Electronic Distribution Mechanism to anyone to whom you made an
200     Executable version available; and if made available via Electronic
201     Distribution Mechanism, must remain available for at least twelve (12)
202     months after the date it initially became available, or at least six
203     (6) months after a subsequent version of that particular Modification
204     has been made available to such recipients. You are responsible for
205     ensuring that the Source Code version remains available even if the
206     Electronic Distribution Mechanism is maintained by a third party.
207
208     3.3. Description of Modifications.
209     You must cause all Covered Code to which You contribute to contain a
210     file documenting the changes You made to create that Covered Code and
211     the date of any change. You must include a prominent statement that
212     the Modification is derived, directly or indirectly, from Original
213     Code provided by the Initial Developer and including the name of the
214     Initial Developer in (a) the Source Code, and (b) in any notice in an
215     Executable version or related documentation in which You describe the
216     origin or ownership of the Covered Code.
217
218     3.4. Intellectual Property Matters
219          (a) Third Party Claims.
220          If Contributor has knowledge that a license under a third party's
221          intellectual property rights is required to exercise the rights
222          granted by such Contributor under Sections 2.1 or 2.2,
223          Contributor must include a text file with the Source Code
224          distribution titled "LEGAL" which describes the claim and the
225          party making the claim in sufficient detail that a recipient will
226          know whom to contact. If Contributor obtains such knowledge after
227          the Modification is made available as described in Section 3.2,
228          Contributor shall promptly modify the LEGAL file in all copies
229          Contributor makes available thereafter and shall take other steps
230          (such as notifying appropriate mailing lists or newsgroups)
231          reasonably calculated to inform those who received the Covered
232          Code that new knowledge has been obtained.
233
234          (b) Contributor APIs.
235          If Contributor's Modifications include an application programming
236          interface and Contributor has knowledge of patent licenses which
237          are reasonably necessary to implement that API, Contributor must
238          also include this information in the LEGAL file.
239
240               (c)    Representations.
241          Contributor represents that, except as disclosed pursuant to
242          Section 3.4(a) above, Contributor believes that Contributor's
243          Modifications are Contributor's original creation(s) and/or
244          Contributor has sufficient rights to grant the rights conveyed by
245          this License.
246
247     3.5. Required Notices.
248     You must duplicate the notice in Exhibit A in each file of the Source
249     Code.  If it is not possible to put such notice in a particular Source
250     Code file due to its structure, then You must include such notice in a
251     location (such as a relevant directory) where a user would be likely
252     to look for such a notice.  If You created one or more Modification(s)
253     You may add your name as a Contributor to the notice described in
254     Exhibit A.  You must also duplicate this License in any documentation
255     for the Source Code where You describe recipients' rights or ownership
256     rights relating to Covered Code.  You may choose to offer, and to
257     charge a fee for, warranty, support, indemnity or liability
258     obligations to one or more recipients of Covered Code. However, You
259     may do so only on Your own behalf, and not on behalf of the Initial
260     Developer or any Contributor. You must make it absolutely clear than
261     any such warranty, support, indemnity or liability obligation is
262     offered by You alone, and You hereby agree to indemnify the Initial
263     Developer and every Contributor for any liability incurred by the
264     Initial Developer or such Contributor as a result of warranty,
265     support, indemnity or liability terms You offer.
266
267     3.6. Distribution of Executable Versions.
268     You may distribute Covered Code in Executable form only if the
269     requirements of Section 3.1-3.5 have been met for that Covered Code,
270     and if You include a notice stating that the Source Code version of
271     the Covered Code is available under the terms of this License,
272     including a description of how and where You have fulfilled the
273     obligations of Section 3.2. The notice must be conspicuously included
274     in any notice in an Executable version, related documentation or
275     collateral in which You describe recipients' rights relating to the
276     Covered Code. You may distribute the Executable version of Covered
277     Code or ownership rights under a license of Your choice, which may
278     contain terms different from this License, provided that You are in
279     compliance with the terms of this License and that the license for the
280     Executable version does not attempt to limit or alter the recipient's
281     rights in the Source Code version from the rights set forth in this
282     License. If You distribute the Executable version under a different
283     license You must make it absolutely clear that any terms which differ
284     from this License are offered by You alone, not by the Initial
285     Developer or any Contributor. You hereby agree to indemnify the
286     Initial Developer and every Contributor for any liability incurred by
287     the Initial Developer or such Contributor as a result of any such
288     terms You offer.
289
290     3.7. Larger Works.
291     You may create a Larger Work by combining Covered Code with other code
292     not governed by the terms of this License and distribute the Larger
293     Work as a single product. In such a case, You must make sure the
294     requirements of this License are fulfilled for the Covered Code.
295
2964. Inability to Comply Due to Statute or Regulation.
297
298     If it is impossible for You to comply with any of the terms of this
299     License with respect to some or all of the Covered Code due to
300     statute, judicial order, or regulation then You must: (a) comply with
301     the terms of this License to the maximum extent possible; and (b)
302     describe the limitations and the code they affect. Such description
303     must be included in the LEGAL file described in Section 3.4 and must
304     be included with all distributions of the Source Code. Except to the
305     extent prohibited by statute or regulation, such description must be
306     sufficiently detailed for a recipient of ordinary skill to be able to
307     understand it.
308
3095. Application of this License.
310
311     This License applies to code to which the Initial Developer has
312     attached the notice in Exhibit A and to related Covered Code.
313
3146. Versions of the License.
315
316     6.1. New Versions.
317     Netscape Communications Corporation ("Netscape") may publish revised
318     and/or new versions of the License from time to time. Each version
319     will be given a distinguishing version number.
320
321     6.2. Effect of New Versions.
322     Once Covered Code has been published under a particular version of the
323     License, You may always continue to use it under the terms of that
324     version. You may also choose to use such Covered Code under the terms
325     of any subsequent version of the License published by Netscape. No one
326     other than Netscape has the right to modify the terms applicable to
327     Covered Code created under this License.
328
329     6.3. Derivative Works.
330     If You create or use a modified version of this License (which you may
331     only do in order to apply it to code which is not already Covered Code
332     governed by this License), You must (a) rename Your license so that
333     the phrases "Mozilla", "MOZILLAPL", "MOZPL", "Netscape",
334     "MPL", "NPL" or any confusingly similar phrase do not appear in your
335     license (except to note that your license differs from this License)
336     and (b) otherwise make it clear that Your version of the license
337     contains terms which differ from the Mozilla Public License and
338     Netscape Public License. (Filling in the name of the Initial
339     Developer, Original Code or Contributor in the notice described in
340     Exhibit A shall not of themselves be deemed to be modifications of
341     this License.)
342
3437. DISCLAIMER OF WARRANTY.
344
345     COVERED CODE IS PROVIDED UNDER THIS LICENSE ON AN "AS IS" BASIS,
346     WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING,
347     WITHOUT LIMITATION, WARRANTIES THAT THE COVERED CODE IS FREE OF
348     DEFECTS, MERCHANTABLE, FIT FOR A PARTICULAR PURPOSE OR NON-INFRINGING.
349     THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE COVERED CODE
350     IS WITH YOU. SHOULD ANY COVERED CODE PROVE DEFECTIVE IN ANY RESPECT,
351     YOU (NOT THE INITIAL DEVELOPER OR ANY OTHER CONTRIBUTOR) ASSUME THE
352     COST OF ANY NECESSARY SERVICING, REPAIR OR CORRECTION. THIS DISCLAIMER
353     OF WARRANTY CONSTITUTES AN ESSENTIAL PART OF THIS LICENSE. NO USE OF
354     ANY COVERED CODE IS AUTHORIZED HEREUNDER EXCEPT UNDER THIS DISCLAIMER.
355
3568. TERMINATION.
357
358     8.1.  This License and the rights granted hereunder will terminate
359     automatically if You fail to comply with terms herein and fail to cure
360     such breach within 30 days of becoming aware of the breach. All
361     sublicenses to the Covered Code which are properly granted shall
362     survive any termination of this License. Provisions which, by their
363     nature, must remain in effect beyond the termination of this License
364     shall survive.
365
366     8.2.  If You initiate litigation by asserting a patent infringement
367     claim (excluding declatory judgment actions) against Initial Developer
368     or a Contributor (the Initial Developer or Contributor against whom
369     You file such action is referred to as "Participant")  alleging that:
370
371     (a)  such Participant's Contributor Version directly or indirectly
372     infringes any patent, then any and all rights granted by such
373     Participant to You under Sections 2.1 and/or 2.2 of this License
374     shall, upon 60 days notice from Participant terminate prospectively,
375     unless if within 60 days after receipt of notice You either: (i)
376     agree in writing to pay Participant a mutually agreeable reasonable
377     royalty for Your past and future use of Modifications made by such
378     Participant, or (ii) withdraw Your litigation claim with respect to
379     the Contributor Version against such Participant.  If within 60 days
380     of notice, a reasonable royalty and payment arrangement are not
381     mutually agreed upon in writing by the parties or the litigation claim
382     is not withdrawn, the rights granted by Participant to You under
383     Sections 2.1 and/or 2.2 automatically terminate at the expiration of
384     the 60 day notice period specified above.
385
386     (b)  any software, hardware, or device, other than such Participant's
387     Contributor Version, directly or indirectly infringes any patent, then
388     any rights granted to You by such Participant under Sections 2.1(b)
389     and 2.2(b) are revoked effective as of the date You first made, used,
390     sold, distributed, or had made, Modifications made by that
391     Participant.
392
393     8.3.  If You assert a patent infringement claim against Participant
394     alleging that such Participant's Contributor Version directly or
395     indirectly infringes any patent where such claim is resolved (such as
396     by license or settlement) prior to the initiation of patent
397     infringement litigation, then the reasonable value of the licenses
398     granted by such Participant under Sections 2.1 or 2.2 shall be taken
399     into account in determining the amount or value of any payment or
400     license.
401
402     8.4.  In the event of termination under Sections 8.1 or 8.2 above,
403     all end user license agreements (excluding distributors and resellers)
404     which have been validly granted by You or any distributor hereunder
405     prior to termination shall survive termination.
406
4079. LIMITATION OF LIABILITY.
408
409     UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY, WHETHER TORT
410     (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL YOU, THE INITIAL
411     DEVELOPER, ANY OTHER CONTRIBUTOR, OR ANY DISTRIBUTOR OF COVERED CODE,
412     OR ANY SUPPLIER OF ANY OF SUCH PARTIES, BE LIABLE TO ANY PERSON FOR
413     ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY
414     CHARACTER INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF GOODWILL,
415     WORK STOPPAGE, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER
416     COMMERCIAL DAMAGES OR LOSSES, EVEN IF SUCH PARTY SHALL HAVE BEEN
417     INFORMED OF THE POSSIBILITY OF SUCH DAMAGES. THIS LIMITATION OF
418     LIABILITY SHALL NOT APPLY TO LIABILITY FOR DEATH OR PERSONAL INJURY
419     RESULTING FROM SUCH PARTY'S NEGLIGENCE TO THE EXTENT APPLICABLE LAW
420     PROHIBITS SUCH LIMITATION. SOME JURISDICTIONS DO NOT ALLOW THE
421     EXCLUSION OR LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO
422     THIS EXCLUSION AND LIMITATION MAY NOT APPLY TO YOU.
423
42410. U.S. GOVERNMENT END USERS.
425
426     The Covered Code is a "commercial item," as that term is defined in
427     48 C.F.R. 2.101 (Oct. 1995), consisting of "commercial computer
428     software" and "commercial computer software documentation," as such
429     terms are used in 48 C.F.R. 12.212 (Sept. 1995). Consistent with 48
430     C.F.R. 12.212 and 48 C.F.R. 227.7202-1 through 227.7202-4 (June 1995),
431     all U.S. Government End Users acquire Covered Code with only those
432     rights set forth herein.
433
43411. MISCELLANEOUS.
435
436     This License represents the complete agreement concerning subject
437     matter hereof. If any provision of this License is held to be
438     unenforceable, such provision shall be reformed only to the extent
439     necessary to make it enforceable. This License shall be governed by
440     California law provisions (except to the extent applicable law, if
441     any, provides otherwise), excluding its conflict-of-law provisions.
442     With respect to disputes in which at least one party is a citizen of,
443     or an entity chartered or registered to do business in the United
444     States of America, any litigation relating to this License shall be
445     subject to the jurisdiction of the Federal Courts of the Northern
446     District of California, with venue lying in Santa Clara County,
447     California, with the losing party responsible for costs, including
448     without limitation, court costs and reasonable attorneys' fees and
449     expenses. The application of the United Nations Convention on
450     Contracts for the International Sale of Goods is expressly excluded.
451     Any law or regulation which provides that the language of a contract
452     shall be construed against the drafter shall not apply to this
453     License.
454
45512. RESPONSIBILITY FOR CLAIMS.
456
457     As between Initial Developer and the Contributors, each party is
458     responsible for claims and damages arising, directly or indirectly,
459     out of its utilization of rights under this License and You agree to
460     work with Initial Developer and Contributors to distribute such
461     responsibility on an equitable basis. Nothing herein is intended or
462     shall be deemed to constitute any admission of liability.
463
46413. MULTIPLE-LICENSED CODE.
465
466     Initial Developer may designate portions of the Covered Code as
467     "Multiple-Licensed".  "Multiple-Licensed" means that the Initial
468     Developer permits you to utilize portions of the Covered Code under
469     Your choice of the NPL or the alternative licenses, if any, specified
470     by the Initial Developer in the file described in Exhibit A.

5490. PREAMBLE
550
551The purpose of this License is to make a manual, textbook, or other
552written document "free" in the sense of freedom: to assure everyone
553the effective freedom to copy and redistribute it, with or without
554modifying it, either commercially or noncommercially.  Secondarily,
555this License preserves for the author and publisher a way to get
556credit for their work, while not being considered responsible for
557modifications made by others.
558
559This License is a kind of "copyleft", which means that derivative
560works of the document must themselves be free in the same sense.  It
561complements the GNU General Public License, which is a copyleft
562license designed for free software.
563
564We have designed this License in order to use it for manuals for free
565software, because free software needs free documentation: a free
566program should come with manuals providing the same freedoms that the
567software does.  But this License is not limited to software manuals;
568it can be used for any textual work, regardless of subject matter or
569whether it is published as a printed book.  We recommend this License
570principally for works whose purpose is instruction or reference.
571
572
5731. APPLICABILITY AND DEFINITIONS
574
575This License applies to any manual or other work that contains a
576notice placed by the copyright holder saying it can be distributed
577under the terms of this License.  The "Document", below, refers to any
578such manual or work.  Any member of the public is a licensee, and is
579addressed as "you".
580
581A "Modified Version" of the Document means any work containing the
582Document or a portion of it, either copied verbatim, or with
583modifications and/or translated into another language.
584
585A "Secondary Section" is a named appendix or a front-matter section of
586the Document that deals exclusively with the relationship of the
587publishers or authors of the Document to the Document's overall subject
588(or to related matters) and contains nothing that could fall directly
589within that overall subject.  (For example, if the Document is in part a
590textbook of mathematics, a Secondary Section may not explain any
591mathematics.)  The relationship could be a matter of historical
592connection with the subject or with related matters, or of legal,
593commercial, philosophical, ethical or political position regarding
594them.
595
596The "Invariant Sections" are certain Secondary Sections whose titles
597are designated, as being those of Invariant Sections, in the notice
598that says that the Document is released under this License.
599
600The "Cover Texts" are certain short passages of text that are listed,
601as Front-Cover Texts or Back-Cover Texts, in the notice that says that
602the Document is released under this License.
603
604A "Transparent" copy of the Document means a machine-readable copy,
605represented in a format whose specification is available to the
606general public, whose contents can be viewed and edited directly and
607straightforwardly with generic text editors or (for images composed of
608pixels) generic paint programs or (for drawings) some widely available
609drawing editor, and that is suitable for input to text formatters or
610for automatic translation to a variety of formats suitable for input
611to text formatters.  A copy made in an otherwise Transparent file
612format whose markup has been designed to thwart or discourage
613subsequent modification by readers is not Transparent.  A copy that is
614not "Transparent" is called "Opaque".
615
616Examples of suitable formats for Transparent copies include plain
617ASCII without markup, Texinfo input format, LaTeX input format, SGML
618or XML using a publicly available DTD, and standard-conforming simple
619HTML designed for human modification.  Opaque formats include
620PostScript, PDF, proprietary formats that can be read and edited only
621by proprietary word processors, SGML or XML for which the DTD and/or
622processing tools are not generally available, and the
623machine-generated HTML produced by some word processors for output
624purposes only.
625
626The "Title Page" means, for a printed book, the title page itself,
627plus such following pages as are needed to hold, legibly, the material
628this License requires to appear in the title page.  For works in
629formats which do not have any title page as such, "Title Page" means
630the text near the most prominent appearance of the work's title,
631preceding the beginning of the body of the text.
632
633
6342. VERBATIM COPYING
635
636You may copy and distribute the Document in any medium, either
637commercially or noncommercially, provided that this License, the
638copyright notices, and the license notice saying this License applies
639to the Document are reproduced in all copies, and that you add no other
640conditions whatsoever to those of this License.  You may not use
641technical measures to obstruct or control the reading or further
642copying of the copies you make or distribute.  However, you may accept
643compensation in exchange for copies.  If you distribute a large enough
644number of copies you must also follow the conditions in section 3.
645
646You may also lend copies, under the same conditions stated above, and
647you may publicly display copies.
648
649
6503. COPYING IN QUANTITY
651
652If you publish printed copies of the Document numbering more than 100,
653and the Document's license notice requires Cover Texts, you must enclose
654the copies in covers that carry, clearly and legibly, all these Cover
655Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
656the back cover.  Both covers must also clearly and legibly identify
657you as the publisher of these copies.  The front cover must present
658the full title with all words of the title equally prominent and
659visible.  You may add other material on the covers in addition.
660Copying with changes limited to the covers, as long as they preserve
661the title of the Document and satisfy these conditions, can be treated
662as verbatim copying in other respects.
663
664If the required texts for either cover are too voluminous to fit
665legibly, you should put the first ones listed (as many as fit
666reasonably) on the actual cover, and continue the rest onto adjacent
667pages.
668
669If you publish or distribute Opaque copies of the Document numbering
670more than 100, you must either include a machine-readable Transparent
671copy along with each Opaque copy, or state in or with each Opaque copy
672a publicly-accessible computer-network location containing a complete
673Transparent copy of the Document, free of added material, which the
674general network-using public has access to download anonymously at no
675charge using public-standard network protocols.  If you use the latter
676option, you must take reasonably prudent steps, when you begin
677distribution of Opaque copies in quantity, to ensure that this
678Transparent copy will remain thus accessible at the stated location
679until at least one year after the last time you distribute an Opaque
680copy (directly or through your agents or retailers) of that edition to
681the public.
682
683It is requested, but not required, that you contact the authors of the
684Document well before redistributing any large number of copies, to give
685them a chance to provide you with an updated version of the Document.
686
687
6884. MODIFICATIONS
689
690You may copy and distribute a Modified Version of the Document under
691the conditions of sections 2 and 3 above, provided that you release
692the Modified Version under precisely this License, with the Modified
693Version filling the role of the Document, thus licensing distribution
694and modification of the Modified Version to whoever possesses a copy
695of it.  In addition, you must do these things in the Modified Version:
696
697A. Use in the Title Page (and on the covers, if any) a title distinct
698   from that of the Document, and from those of previous versions
699   (which should, if there were any, be listed in the History section
700   of the Document).  You may use the same title as a previous version
701   if the original publisher of that version gives permission.
702B. List on the Title Page, as authors, one or more persons or entities
703   responsible for authorship of the modifications in the Modified
704   Version, together with at least five of the principal authors of the
705   Document (all of its principal authors, if it has less than five).
706C. State on the Title page the name of the publisher of the
707   Modified Version, as the publisher.
708D. Preserve all the copyright notices of the Document.
709E. Add an appropriate copyright notice for your modifications
710   adjacent to the other copyright notices.
711F. Include, immediately after the copyright notices, a license notice
712   giving the public permission to use the Modified Version under the
713   terms of this License, in the form shown in the Addendum below.
714G. Preserve in that license notice the full lists of Invariant Sections
715   and required Cover Texts given in the Document's license notice.
716H. Include an unaltered copy of this License.
717I. Preserve the section entitled "History", and its title, and add to
718   it an item stating at least the title, year, new authors, and
719   publisher of the Modified Version as given on the Title Page.  If
720   there is no section entitled "History" in the Document, create one
721   stating the title, year, authors, and publisher of the Document as
722   given on its Title Page, then add an item describing the Modified
723   Version as stated in the previous sentence.
724J. Preserve the network location, if any, given in the Document for
725   public access to a Transparent copy of the Document, and likewise
726   the network locations given in the Document for previous versions
727   it was based on.  These may be placed in the "History" section.
728   You may omit a network location for a work that was published at
729   least four years before the Document itself, or if the original
730   publisher of the version it refers to gives permission.
731K. In any section entitled "Acknowledgements" or "Dedications",
732   preserve the section's title, and preserve in the section all the
733   substance and tone of each of the contributor acknowledgements
734   and/or dedications given therein.
735L. Preserve all the Invariant Sections of the Document,
736   unaltered in their text and in their titles.  Section numbers
737   or the equivalent are not considered part of the section titles.
738M. Delete any section entitled "Endorsements".  Such a section
739   may not be included in the Modified Version.
740N. Do not retitle any existing section as "Endorsements"
741   or to conflict in title with any Invariant Section.
742
743If the Modified Version includes new front-matter sections or
744appendices that qualify as Secondary Sections and contain no material
745copied from the Document, you may at your option designate some or all
746of these sections as invariant.  To do this, add their titles to the
747list of Invariant Sections in the Modified Version's license notice.
748These titles must be distinct from any other section titles.
749
750You may add a section entitled "Endorsements", provided it contains
751nothing but endorsements of your Modified Version by various
752parties--for example, statements of peer review or that the text has
753been approved by an organization as the authoritative definition of a
754standard.
755
756You may add a passage of up to five words as a Front-Cover Text, and a
757passage of up to 25 words as a Back-Cover Text, to the end of the list
758of Cover Texts in the Modified Version.  Only one passage of
759Front-Cover Text and one of Back-Cover Text may be added by (or
760through arrangements made by) any one entity.  If the Document already
761includes a cover text for the same cover, previously added by you or
762by arrangement made by the same entity you are acting on behalf of,
763you may not add another; but you may replace the old one, on explicit
764permission from the previous publisher that added the old one.
765
766The author(s) and publisher(s) of the Document do not by this License
767give permission to use their names for publicity for or to assert or
768imply endorsement of any Modified Version.
769
770
7715. COMBINING DOCUMENTS
772
773You may combine the Document with other documents released under this
774License, under the terms defined in section 4 above for modified
775versions, provided that you include in the combination all of the
776Invariant Sections of all of the original documents, unmodified, and
777list them all as Invariant Sections of your combined work in its
778license notice.
779
780The combined work need only contain one copy of this License, and
781multiple identical Invariant Sections may be replaced with a single
782copy.  If there are multiple Invariant Sections with the same name but
783different contents, make the title of each such section unique by
784adding at the end of it, in parentheses, the name of the original
785author or publisher of that section if known, or else a unique number.
786Make the same adjustment to the section titles in the list of
787Invariant Sections in the license notice of the combined work.
788
789In the combination, you must combine any sections entitled "History"
790in the various original documents, forming one section entitled
791"History"; likewise combine any sections entitled "Acknowledgements",
792and any sections entitled "Dedications".  You must delete all sections
793entitled "Endorsements."
794
795
7966. COLLECTIONS OF DOCUMENTS
797
798You may make a collection consisting of the Document and other documents
799released under this License, and replace the individual copies of this
800License in the various documents with a single copy that is included in
801the collection, provided that you follow the rules of this License for
802verbatim copying of each of the documents in all other respects.
803
804You may extract a single document from such a collection, and distribute
805it individually under this License, provided you insert a copy of this
806License into the extracted document, and follow this License in all
807other respects regarding verbatim copying of that document.
808
809
8107. AGGREGATION WITH INDEPENDENT WORKS
811
812A compilation of the Document or its derivatives with other separate
813and independent documents or works, in or on a volume of a storage or
814distribution medium, does not as a whole count as a Modified Version
815of the Document, provided no compilation copyright is claimed for the
816compilation.  Such a compilation is called an "aggregate", and this
817License does not apply to the other self-contained works thus compiled
818with the Document, on account of their being thus compiled, if they
819are not themselves derivative works of the Document.
820
821If the Cover Text requirement of section 3 is applicable to these
822copies of the Document, then if the Document is less than one quarter
823of the entire aggregate, the Document's Cover Texts may be placed on
824covers that surround only the Document within the aggregate.
825Otherwise they must appear on covers around the whole aggregate.
826
827
8288. TRANSLATION
829
830Translation is considered a kind of modification, so you may
831distribute translations of the Document under the terms of section 4.
832Replacing Invariant Sections with translations requires special
833permission from their copyright holders, but you may include
834translations of some or all Invariant Sections in addition to the
835original versions of these Invariant Sections.  You may include a
836translation of this License provided that you also include the
837original English version of this License.  In case of a disagreement
838between the translation and the original English version of this
839License, the original English version will prevail.
840
841
8429. TERMINATION
843
844You may not copy, modify, sublicense, or distribute the Document except
845as expressly provided for under this License.  Any other attempt to
846copy, modify, sublicense or distribute the Document is void, and will
847automatically terminate your rights under this License.  However,
848parties who have received copies, or rights, from you under this
849License will not have their licenses terminated so long as such
850parties remain in full compliance.
851
852
85310. FUTURE REVISIONS OF THIS LICENSE
854
855The Free Software Foundation may publish new, revised versions
856of the GNU Free Documentation License from time to time.  Such new
857versions will be similar in spirit to the present version, but may
858differ in detail to address new problems or concerns.  See
859http://www.gnu.org/copyleft/.
860
861Each version of the License is given a distinguishing version number.
862If the Document specifies that a particular numbered version of this
863License "or any later version" applies to it, you have the option of
864following the terms and conditions either of that specified version or
865of any later version that has been published (not as a draft) by the
866Free Software Foundation.  If the Document does not specify a version
867number of this License, you may choose any version ever published (not
868as a draft) by the Free Software Foundation.
869
870
871ADDENDUM: How to use this License for your documents
872
873To use this License in a document you have written, include a copy of
874the License in the document and put the following copyright and
875license notices just after the title page:
876
877      Copyright (c)  YEAR  YOUR NAME.
878      Permission is granted to copy, distribute and/or modify this document
879      under the terms of the GNU Free Documentation License, Version 1.1
880      or any later version published by the Free Software Foundation;
881      with the Invariant Sections being LIST THEIR TITLES, with the
882      Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
883      A copy of the license is included in the section entitled "GNU
884      Free Documentation License".
885
886If you have no Invariant Sections, write "with no Invariant Sections"
887instead of saying which ones are invariant.  If you have no
888Front-Cover Texts, write "no Front-Cover Texts" instead of
889"Front-Cover Texts being LIST"; likewise for Back-Cover Texts.
890
891If your document contains nontrivial examples of program code, we
892recommend releasing these examples in parallel under your choice of
893free software license, such as the GNU General Public License,
894to permit their use in free software.
