joachim99@69: Version 1.1, March 2000 joachim99@69: joachim99@69:

Copyright (C) 2000 Free Software Foundation, Inc. joachim99@69: 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
joachim99@69: Everyone is permitted to copy and distribute verbatim copies joachim99@69: of this license document, but changing it is not allowed.

joachim99@69: joachim99@69:

0. Preamble

joachim99@69: joachim99@69:

The purpose of this License is to make a manual, textbook, or other joachim99@69: written document "free" in the sense of freedom: to assure everyone joachim99@69: the effective freedom to copy and redistribute it, with or without joachim99@69: modifying it, either commercially or noncommercially. Secondarily, joachim99@69: this License preserves for the author and publisher a way to get joachim99@69: credit for their work, while not being considered responsible for joachim99@69: modifications made by others.

joachim99@69: joachim99@69:

This License is a kind of "copyleft", which means that derivative joachim99@69: works of the document must themselves be free in the same sense. It joachim99@69: complements the GNU General Public License, which is a copyleft joachim99@69: license designed for free software.

joachim99@69: joachim99@69:

We have designed this License in order to use it for manuals for free joachim99@69: software, because free software needs free documentation: a free joachim99@69: program should come with manuals providing the same freedoms that the joachim99@69: software does. But this License is not limited to software manuals; joachim99@69: it can be used for any textual work, regardless of subject matter or joachim99@69: whether it is published as a printed book. We recommend this License joachim99@69: principally for works whose purpose is instruction or reference.

joachim99@69: joachim99@69:

1. Applicability And Definitions

joachim99@69: joachim99@69:

This License applies to any manual or other work that contains a joachim99@69: notice placed by the copyright holder saying it can be distributed joachim99@69: under the terms of this License. The "Document", below, refers to any joachim99@69: such manual or work. Any member of the public is a licensee, and is joachim99@69: addressed as "you".

joachim99@69: joachim99@69:

A "Modified Version" of the Document means any work containing the joachim99@69: Document or a portion of it, either copied verbatim, or with joachim99@69: modifications and/or translated into another language.

joachim99@69: joachim99@69:

A "Secondary Section" is a named appendix or a front-matter section of joachim99@69: the Document that deals exclusively with the relationship of the joachim99@69: publishers or authors of the Document to the Document's overall subject joachim99@69: (or to related matters) and contains nothing that could fall directly joachim99@69: within that overall subject. (For example, if the Document is in part a joachim99@69: textbook of mathematics, a Secondary Section may not explain any joachim99@69: mathematics.) The relationship could be a matter of historical joachim99@69: connection with the subject or with related matters, or of legal, joachim99@69: commercial, philosophical, ethical or political position regarding joachim99@69: them.

joachim99@69: joachim99@69:

The "Invariant Sections" are certain Secondary Sections whose titles joachim99@69: are designated, as being those of Invariant Sections, in the notice joachim99@69: that says that the Document is released under this License.

joachim99@69: joachim99@69:

The "Cover Texts" are certain short passages of text that are listed, joachim99@69: as Front-Cover Texts or Back-Cover Texts, in the notice that says that joachim99@69: the Document is released under this License.

joachim99@69: joachim99@69:

A "Transparent" copy of the Document means a machine-readable copy, joachim99@69: represented in a format whose specification is available to the joachim99@69: general public, whose contents can be viewed and edited directly and joachim99@69: straightforwardly with generic text editors or (for images composed of joachim99@69: pixels) generic paint programs or (for drawings) some widely available joachim99@69: drawing editor, and that is suitable for input to text formatters or joachim99@69: for automatic translation to a variety of formats suitable for input joachim99@69: to text formatters. A copy made in an otherwise Transparent file joachim99@69: format whose markup has been designed to thwart or discourage joachim99@69: subsequent modification by readers is not Transparent. A copy that is joachim99@69: not "Transparent" is called "Opaque".

joachim99@69: joachim99@69:

Examples of suitable formats for Transparent copies include plain joachim99@69: ASCII without markup, Texinfo input format, LaTeX input format, SGML joachim99@69: or XML using a publicly available DTD, and standard-conforming simple joachim99@69: HTML designed for human modification. Opaque formats include joachim99@69: PostScript, PDF, proprietary formats that can be read and edited only joachim99@69: by proprietary word processors, SGML or XML for which the DTD and/or joachim99@69: processing tools are not generally available, and the joachim99@69: machine-generated HTML produced by some word processors for output joachim99@69: purposes only.

joachim99@69: joachim99@69:

The "Title Page" means, for a printed book, the title page itself, joachim99@69: plus such following pages as are needed to hold, legibly, the material joachim99@69: this License requires to appear in the title page. For works in joachim99@69: formats which do not have any title page as such, "Title Page" means joachim99@69: the text near the most prominent appearance of the work's title, joachim99@69: preceding the beginning of the body of the text.

joachim99@69: joachim99@69:

2. Verbatim Copying

joachim99@69: joachim99@69:

You may copy and distribute the Document in any medium, either joachim99@69: commercially or noncommercially, provided that this License, the joachim99@69: copyright notices, and the license notice saying this License applies joachim99@69: to the Document are reproduced in all copies, and that you add no other joachim99@69: conditions whatsoever to those of this License. You may not use joachim99@69: technical measures to obstruct or control the reading or further joachim99@69: copying of the copies you make or distribute. However, you may accept joachim99@69: compensation in exchange for copies. If you distribute a large enough joachim99@69: number of copies you must also follow the conditions in section 3.

joachim99@69: joachim99@69:

You may also lend copies, under the same conditions stated above, and joachim99@69: you may publicly display copies.

joachim99@69: joachim99@69:

3. Copying In Quantity

joachim99@69: joachim99@69:

If you publish printed copies of the Document numbering more than 100, joachim99@69: and the Document's license notice requires Cover Texts, you must enclose joachim99@69: the copies in covers that carry, clearly and legibly, all these Cover joachim99@69: Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on joachim99@69: the back cover. Both covers must also clearly and legibly identify joachim99@69: you as the publisher of these copies. The front cover must present joachim99@69: the full title with all words of the title equally prominent and joachim99@69: visible. You may add other material on the covers in addition. joachim99@69: Copying with changes limited to the covers, as long as they preserve joachim99@69: the title of the Document and satisfy these conditions, can be treated joachim99@69: as verbatim copying in other respects.

joachim99@69: joachim99@69:

If the required texts for either cover are too voluminous to fit joachim99@69: legibly, you should put the first ones listed (as many as fit joachim99@69: reasonably) on the actual cover, and continue the rest onto adjacent joachim99@69: pages.

joachim99@69: joachim99@69:

If you publish or distribute Opaque copies of the Document numbering joachim99@69: more than 100, you must either include a machine-readable Transparent joachim99@69: copy along with each Opaque copy, or state in or with each Opaque copy joachim99@69: a publicly-accessible computer-network location containing a complete joachim99@69: Transparent copy of the Document, free of added material, which the joachim99@69: general network-using public has access to download anonymously at no joachim99@69: charge using public-standard network protocols. If you use the latter joachim99@69: option, you must take reasonably prudent steps, when you begin joachim99@69: distribution of Opaque copies in quantity, to ensure that this joachim99@69: Transparent copy will remain thus accessible at the stated location joachim99@69: until at least one year after the last time you distribute an Opaque joachim99@69: copy (directly or through your agents or retailers) of that edition to joachim99@69: the public.

joachim99@69: joachim99@69:

It is requested, but not required, that you contact the authors of the joachim99@69: Document well before redistributing any large number of copies, to give joachim99@69: them a chance to provide you with an updated version of the Document.

joachim99@69: joachim99@69:

4. Modifications

joachim99@69: joachim99@69:

You may copy and distribute a Modified Version of the Document under joachim99@69: the conditions of sections 2 and 3 above, provided that you release joachim99@69: the Modified Version under precisely this License, with the Modified joachim99@69: Version filling the role of the Document, thus licensing distribution joachim99@69: and modification of the Modified Version to whoever possesses a copy joachim99@69: of it. In addition, you must do these things in the Modified Version:

joachim99@69: joachim99@69:
    joachim99@69:
  1. Use in the Title Page (and on the covers, if any) a title distinct joachim99@69: from that of the Document, and from those of previous versions joachim99@69: (which should, if there were any, be listed in the History section joachim99@69: of the Document). You may use the same title as a previous joachim99@69: version if the original publisher of that version gives joachim99@69: permission.
    2. joachim99@69: joachim99@69:
  2. List on the Title Page, as authors, one or more persons or joachim99@69: entities responsible for authorship of the modifications in the joachim99@69: Modified Version, together with at least five of the principal joachim99@69: authors of the Document (all of its principal authors, if it has joachim99@69: less than five).
    3. joachim99@69: joachim99@69:
  3. State on the Title page the name of the publisher of the Modified joachim99@69: Version, as the publisher.
    4. joachim99@69: joachim99@69:
  4. Preserve all the copyright notices of the Document.
    5. joachim99@69: joachim99@69:
  5. Add an appropriate copyright notice for your modifications joachim99@69: adjacent to the other copyright notices.
    6. joachim99@69: joachim99@69:
  6. Include, immediately after the copyright notices, a license notice joachim99@69: giving the public permission to use the Modified Version under the joachim99@69: terms of this License, in the form shown in the Addendum joachim99@69: below.
    7. joachim99@69: joachim99@69:
  7. Preserve in that license notice the full lists of Invariant joachim99@69: Sections and required Cover Texts given in the Document's license joachim99@69: notice.
    8. joachim99@69: joachim99@69:
  8. Include an unaltered copy of this License.
    9. joachim99@69: joachim99@69:
  9. Preserve the section entitled "History", and its title, and add to joachim99@69: it an item stating at least the title, year, new authors, and joachim99@69: publisher of the Modified Version as given on the Title Page. If joachim99@69: there is no section entitled "History" in the Document, create one joachim99@69: stating the title, year, authors, and publisher of the Document as joachim99@69: given on its Title Page, then add an item describing the Modified joachim99@69: Version as stated in the previous sentence.
    10. joachim99@69: joachim99@69:
  10. Preserve the network location, if any, given in the Document for joachim99@69: public access to a Transparent copy of the Document, and likewise joachim99@69: the network locations given in the Document for previous versions joachim99@69: it was based on. These may be placed in the "History" section. joachim99@69: You may omit a network location for a work that was published at joachim99@69: least four years before the Document itself, or if the original joachim99@69: publisher of the version it refers to gives permission.
    11. joachim99@69: joachim99@69:
  11. In any section entitled "Acknowledgements" or "Dedications", joachim99@69: preserve the section's title, and preserve in the section all the joachim99@69: substance and tone of each of the contributor acknowledgements joachim99@69: and/or dedications given therein.
    12. joachim99@69: joachim99@69:
  12. Preserve all the Invariant Sections of the Document, unaltered in joachim99@69: their text and in their titles. Section numbers or the equivalent joachim99@69: are not considered part of the section titles.
    13. joachim99@69: joachim99@69:
  13. Delete any section entitled "Endorsements". Such a section may joachim99@69: not be included in the Modified Version.
    14. joachim99@69: joachim99@69:
  14. Do not retitle any existing section as "Endorsements" or to joachim99@69: conflict in title with any Invariant Section.
    15. joachim99@69:
joachim99@69: joachim99@69:

If the Modified Version includes new front-matter sections or joachim99@69: appendices that qualify as Secondary Sections and contain no material joachim99@69: copied from the Document, you may at your option designate some or all joachim99@69: of these sections as invariant. To do this, add their titles to the joachim99@69: list of Invariant Sections in the Modified Version's license notice. joachim99@69: These titles must be distinct from any other section titles.

joachim99@69: joachim99@69:

You may add a section entitled "Endorsements", provided it contains joachim99@69: nothing but endorsements of your Modified Version by various joachim99@69: parties--for example, statements of peer review or that the text has joachim99@69: been approved by an organization as the authoritative definition of a joachim99@69: standard.

joachim99@69: joachim99@69:

You may add a passage of up to five words as a Front-Cover Text, and a joachim99@69: passage of up to 25 words as a Back-Cover Text, to the end of the list joachim99@69: of Cover Texts in the Modified Version. Only one passage of joachim99@69: Front-Cover Text and one of Back-Cover Text may be added by (or joachim99@69: through arrangements made by) any one entity. If the Document already joachim99@69: includes a cover text for the same cover, previously added by you or joachim99@69: by arrangement made by the same entity you are acting on behalf of, joachim99@69: you may not add another; but you may replace the old one, on explicit joachim99@69: permission from the previous publisher that added the old one.

joachim99@69: joachim99@69:

The author(s) and publisher(s) of the Document do not by this License joachim99@69: give permission to use their names for publicity for or to assert or joachim99@69: imply endorsement of any Modified Version.

joachim99@69: joachim99@69:

5. Combining Documents

joachim99@69: joachim99@69:

You may combine the Document with other documents released under this joachim99@69: License, under the terms defined in section 4 above for modified joachim99@69: versions, provided that you include in the combination all of the joachim99@69: Invariant Sections of all of the original documents, unmodified, and joachim99@69: list them all as Invariant Sections of your combined work in its joachim99@69: license notice.

joachim99@69: joachim99@69:

The combined work need only contain one copy of this License, and joachim99@69: multiple identical Invariant Sections may be replaced with a single joachim99@69: copy. If there are multiple Invariant Sections with the same name but joachim99@69: different contents, make the title of each such section unique by joachim99@69: adding at the end of it, in parentheses, the name of the original joachim99@69: author or publisher of that section if known, or else a unique number. joachim99@69: Make the same adjustment to the section titles in the list of joachim99@69: Invariant Sections in the license notice of the combined work.

joachim99@69: joachim99@69:

In the combination, you must combine any sections entitled "History" joachim99@69: in the various original documents, forming one section entitled joachim99@69: "History"; likewise combine any sections entitled "Acknowledgements", joachim99@69: and any sections entitled "Dedications". You must delete all sections joachim99@69: entitled "Endorsements."

joachim99@69: joachim99@69:

6. Collections Of Documents

joachim99@69: joachim99@69:

You may make a collection consisting of the Document and other documents joachim99@69: released under this License, and replace the individual copies of this joachim99@69: License in the various documents with a single copy that is included in joachim99@69: the collection, provided that you follow the rules of this License for joachim99@69: verbatim copying of each of the documents in all other respects.

joachim99@69: joachim99@69:

You may extract a single document from such a collection, and distribute joachim99@69: it individually under this License, provided you insert a copy of this joachim99@69: License into the extracted document, and follow this License in all joachim99@69: other respects regarding verbatim copying of that document.

joachim99@69: joachim99@69:

7. Aggregation With Independent Works

joachim99@69: joachim99@69:

A compilation of the Document or its derivatives with other separate joachim99@69: and independent documents or works, in or on a volume of a storage or joachim99@69: distribution medium, does not as a whole count as a Modified Version joachim99@69: of the Document, provided no compilation copyright is claimed for the joachim99@69: compilation. Such a compilation is called an "aggregate", and this joachim99@69: License does not apply to the other self-contained works thus compiled joachim99@69: with the Document, on account of their being thus compiled, if they joachim99@69: are not themselves derivative works of the Document.

joachim99@69: joachim99@69:

If the Cover Text requirement of section 3 is applicable to these joachim99@69: copies of the Document, then if the Document is less than one quarter joachim99@69: of the entire aggregate, the Document's Cover Texts may be placed on joachim99@69: covers that surround only the Document within the aggregate. joachim99@69: Otherwise they must appear on covers around the whole aggregate.

joachim99@69: joachim99@69:

8. Translation

joachim99@69: joachim99@69:

Translation is considered a kind of modification, so you may joachim99@69: distribute translations of the Document under the terms of section 4. joachim99@69: Replacing Invariant Sections with translations requires special joachim99@69: permission from their copyright holders, but you may include joachim99@69: translations of some or all Invariant Sections in addition to the joachim99@69: original versions of these Invariant Sections. You may include a joachim99@69: translation of this License provided that you also include the joachim99@69: original English version of this License. In case of a disagreement joachim99@69: between the translation and the original English version of this joachim99@69: License, the original English version will prevail.

joachim99@69: joachim99@69:

9. Termination

joachim99@69: joachim99@69:

You may not copy, modify, sublicense, or distribute the Document except joachim99@69: as expressly provided for under this License. Any other attempt to joachim99@69: copy, modify, sublicense or distribute the Document is void, and will joachim99@69: automatically terminate your rights under this License. However, joachim99@69: parties who have received copies, or rights, from you under this joachim99@69: License will not have their licenses terminated so long as such joachim99@69: parties remain in full compliance.

joachim99@69: joachim99@69:

10. Future Revisions Of This License

joachim99@69: joachim99@69:

The Free Software Foundation may publish new, revised versions joachim99@69: of the GNU Free Documentation License from time to time. Such new joachim99@69: versions will be similar in spirit to the present version, but may joachim99@69: differ in detail to address new problems or concerns. See joachim99@69: http:///www.gnu.org/copyleft/.

joachim99@69: joachim99@69:

Each version of the License is given a distinguishing version number. joachim99@69: If the Document specifies that a particular numbered version of this joachim99@69: License "or any later version" applies to it, you have the option of joachim99@69: following the terms and conditions either of that specified version or joachim99@69: of any later version that has been published (not as a draft) by the joachim99@69: Free Software Foundation. If the Document does not specify a version joachim99@69: number of this License, you may choose any version ever published (not joachim99@69: as a draft) by the Free Software Foundation.

joachim99@69: joachim99@69:
