-Funding Free Software
-*********************
-
- If you want to have more free software a few years from now, it makes
-sense for you to help encourage people to contribute funds for its
-development. The most effective approach known is to encourage
-commercial redistributors to donate.
-
- Users of free software systems can boost the pace of development by
-encouraging for-a-fee distributors to donate part of their selling price
-to free software developers--the Free Software Foundation, and others.
-
- The way to convince distributors to do this is to demand it and
-expect it from them. So when you compare distributors, judge them
-partly by how much they give to free software development. Show
-distributors they must compete to be the one who gives the most.
-
- To make this approach work, you must insist on numbers that you can
-compare, such as, "We will donate ten dollars to the Frobnitz project
-for each disk sold." Don't be satisfied with a vague promise, such as
-"A portion of the profits are donated," since it doesn't give a basis
-for comparison.
-
- Even a precise fraction "of the profits from this disk" is not very
-meaningful, since creative accounting and unrelated business decisions
-can greatly alter what fraction of the sales price counts as profit.
-If the price you pay is $50, ten percent of the profit is probably less
-than a dollar; it might be a few cents, or nothing at all.
-
- Some redistributors do development work themselves. This is useful
-too; but to keep everyone honest, you need to inquire how much they do,
-and what kind. Some kinds of development make much more long-term
-difference than others. For example, maintaining a separate version of
-a program contributes very little; maintaining the standard version of a
-program for the whole community contributes much. Easy new ports
-contribute little, since someone else would surely do them; difficult
-ports such as adding a new CPU to the GNU Compiler Collection
-contribute more; major new features or packages contribute the most.
-
- By establishing the idea that supporting further development is "the
-proper thing to do" when distributing free software for a fee, we can
-assure a steady flow of resources into making more free software.

-The GNU Project and GNU/Linux
-*****************************
-
- The GNU Project was launched in 1984 to develop a complete Unix-like
-operating system which is free software: the GNU system. (GNU is a
-recursive acronym for "GNU's Not Unix"; it is pronounced "guh-NEW".)
-Variants of the GNU operating system, which use the kernel Linux, are
-now widely used; though these systems are often referred to as "Linux",
-they are more accurately called GNU/Linux systems.

-GNU GENERAL PUBLIC LICENSE
-**************************
-
- Version 2, June 1991
- Copyright (C) 1989, 1991 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.
-
-Preamble
-========
-
- The licenses for most software are designed to take away your
-freedom to share and change it. By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.) You can apply it to
-your programs, too.
-
- When we speak of free software, we are referring to freedom, not
-price. Our General Public Licenses are designed to make sure that you
-have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it in
-new free programs; and that you know you can do these things.
-
- To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
-
- For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
-
- We protect your rights with two steps: (1) copyright the software,
-and (2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
- Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
-
- Finally, any free program is threatened constantly by software
-patents. We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
-
- The precise terms and conditions for copying, distribution and
-modification follow.
-
- TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
- 0. This License applies to any program or other work which contains a
- notice placed by the copyright holder saying it may be distributed
- under the terms of this General Public License. The "Program",
- below, refers to any such program or work, and a "work based on
- the Program" means either the Program or any derivative work under
- copyright law: that is to say, a work containing the Program or a
- portion of it, either verbatim or with modifications and/or
- translated into another language. (Hereinafter, translation is
- included without limitation in the term "modification".) Each
- licensee is addressed as "you".
-
- Activities other than copying, distribution and modification are
- not covered by this License; they are outside its scope. The act
- of running the Program is not restricted, and the output from the
- Program is covered only if its contents constitute a work based on
- the Program (independent of having been made by running the
- Program). Whether that is true depends on what the Program does.
-
- 1. You may copy and distribute verbatim copies of the Program's
- source code as you receive it, in any medium, provided that you
- conspicuously and appropriately publish on each copy an appropriate
- copyright notice and disclaimer of warranty; keep intact all the
- notices that refer to this License and to the absence of any
- warranty; and give any other recipients of the Program a copy of
- this License along with the Program.
-
- You may charge a fee for the physical act of transferring a copy,
- and you may at your option offer warranty protection in exchange
- for a fee.
-
- 2. You may modify your copy or copies of the Program or any portion
- of it, thus forming a work based on the Program, and copy and
- distribute such modifications or work under the terms of Section 1
- above, provided that you also meet all of these conditions:
-
- a. You must cause the modified files to carry prominent notices
- stating that you changed the files and the date of any change.
-
- b. You must cause any work that you distribute or publish, that
- in whole or in part contains or is derived from the Program
- or any part thereof, to be licensed as a whole at no charge
- to all third parties under the terms of this License.
-
- c. If the modified program normally reads commands interactively
- when run, you must cause it, when started running for such
- interactive use in the most ordinary way, to print or display
- an announcement including an appropriate copyright notice and
- a notice that there is no warranty (or else, saying that you
- provide a warranty) and that users may redistribute the
- program under these conditions, and telling the user how to
- view a copy of this License. (Exception: if the Program
- itself is interactive but does not normally print such an
- announcement, your work based on the Program is not required
- to print an announcement.)
-
- These requirements apply to the modified work as a whole. If
- identifiable sections of that work are not derived from the
- Program, and can be reasonably considered independent and separate
- works in themselves, then this License, and its terms, do not
- apply to those sections when you distribute them as separate
- works. But when you distribute the same sections as part of a
- whole which is a work based on the Program, the distribution of
- the whole must be on the terms of this License, whose permissions
- for other licensees extend to the entire whole, and thus to each
- and every part regardless of who wrote it.
-
- Thus, it is not the intent of this section to claim rights or
- contest your rights to work written entirely by you; rather, the
- intent is to exercise the right to control the distribution of
- derivative or collective works based on the Program.
-
- In addition, mere aggregation of another work not based on the
- Program with the Program (or with a work based on the Program) on
- a volume of a storage or distribution medium does not bring the
- other work under the scope of this License.
-
- 3. You may copy and distribute the Program (or a work based on it,
- under Section 2) in object code or executable form under the terms
- of Sections 1 and 2 above provided that you also do one of the
- following:
-
- a. Accompany it with the complete corresponding machine-readable
- source code, which must be distributed under the terms of
- Sections 1 and 2 above on a medium customarily used for
- software interchange; or,
-
- b. Accompany it with a written offer, valid for at least three
- years, to give any third party, for a charge no more than your
- cost of physically performing source distribution, a complete
- machine-readable copy of the corresponding source code, to be
- distributed under the terms of Sections 1 and 2 above on a
- medium customarily used for software interchange; or,
-
- c. Accompany it with the information you received as to the offer
- to distribute corresponding source code. (This alternative is
- allowed only for noncommercial distribution and only if you
- received the program in object code or executable form with
- such an offer, in accord with Subsection b above.)
-
- The source code for a work means the preferred form of the work for
- making modifications to it. For an executable work, complete
- source code means all the source code for all modules it contains,
- plus any associated interface definition files, plus the scripts
- used to control compilation and installation of the executable.
- However, as a special exception, the source code distributed need
- not include anything that is normally distributed (in either
- source or binary form) with the major components (compiler,
- kernel, and so on) of the operating system on which the executable
- runs, unless that component itself accompanies the executable.
-
- If distribution of executable or object code is made by offering
- access to copy from a designated place, then offering equivalent
- access to copy the source code from the same place counts as
- distribution of the source code, even though third parties are not
- compelled to copy the source along with the object code.
-
- 4. You may not copy, modify, sublicense, or distribute the Program
- except as expressly provided under this License. Any attempt
- otherwise to copy, modify, sublicense or distribute the Program 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.
-
- 5. You are not required to accept this License, since you have not
- signed it. However, nothing else grants you permission to modify
- or distribute the Program or its derivative works. These actions
- are prohibited by law if you do not accept this License.
- Therefore, by modifying or distributing the Program (or any work
- based on the Program), you indicate your acceptance of this
- License to do so, and all its terms and conditions for copying,
- distributing or modifying the Program or works based on it.
-
- 6. Each time you redistribute the Program (or any work based on the
- Program), the recipient automatically receives a license from the
- original licensor to copy, distribute or modify the Program
- subject to these terms and conditions. You may not impose any
- further restrictions on the recipients' exercise of the rights
- granted herein. You are not responsible for enforcing compliance
- by third parties to this License.
-
- 7. If, as a consequence of a court judgment or allegation of patent
- infringement or for any other reason (not limited to patent
- issues), conditions are imposed on you (whether by court order,
- agreement or otherwise) that contradict the conditions of this
- License, they do not excuse you from the conditions of this
- License. If you cannot distribute so as to satisfy simultaneously
- your obligations under this License and any other pertinent
- obligations, then as a consequence you may not distribute the
- Program at all. For example, if a patent license would not permit
- royalty-free redistribution of the Program by all those who
- receive copies directly or indirectly through you, then the only
- way you could satisfy both it and this License would be to refrain
- entirely from distribution of the Program.
-
- If any portion of this section is held invalid or unenforceable
- under any particular circumstance, the balance of the section is
- intended to apply and the section as a whole is intended to apply
- in other circumstances.
-
- It is not the purpose of this section to induce you to infringe any
- patents or other property right claims or to contest validity of
- any such claims; this section has the sole purpose of protecting
- the integrity of the free software distribution system, which is
- implemented by public license practices. Many people have made
- generous contributions to the wide range of software distributed
- through that system in reliance on consistent application of that
- system; it is up to the author/donor to decide if he or she is
- willing to distribute software through any other system and a
- licensee cannot impose that choice.
-
- This section is intended to make thoroughly clear what is believed
- to be a consequence of the rest of this License.
-
- 8. If the distribution and/or use of the Program is restricted in
- certain countries either by patents or by copyrighted interfaces,
- the original copyright holder who places the Program under this
- License may add an explicit geographical distribution limitation
- excluding those countries, so that distribution is permitted only
- in or among countries not thus excluded. In such case, this
- License incorporates the limitation as if written in the body of
- this License.
-
- 9. The Free Software Foundation may publish revised and/or new
- versions of the General Public 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.
-
- Each version is given a distinguishing version number. If the
- Program specifies a version number of this License which applies
- to it and "any later version", you have the option of following
- the terms and conditions either of that version or of any later
- version published by the Free Software Foundation. If the Program
- does not specify a version number of this License, you may choose
- any version ever published by the Free Software Foundation.
-
- 10. If you wish to incorporate parts of the Program into other free
- programs whose distribution conditions are different, write to the
- author to ask for permission. For software which is copyrighted
- by the Free Software Foundation, write to the Free Software
- Foundation; we sometimes make exceptions for this. Our decision
- will be guided by the two goals of preserving the free status of
- all derivatives of our free software and of promoting the sharing
- and reuse of software generally.
-
- NO WARRANTY
-
- 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
- WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
- LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
- HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
- WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
- NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
- FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
- QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
- PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
- SERVICING, REPAIR OR CORRECTION.
-
- 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
- WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
- MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
- LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
- INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
- INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
- DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
- OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY
- OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
- ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
-
- END OF TERMS AND CONDITIONS
-
-How to Apply These Terms to Your New Programs
-=============================================
-
- If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these
-terms.
-
- To do so, attach the following notices to the program. It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
- ONE LINE TO GIVE THE PROGRAM'S NAME AND A BRIEF IDEA OF WHAT IT DOES.
- Copyright (C) YEAR NAME OF AUTHOR
-
- This program is free software; you can redistribute it and/or modify
- it under the terms of the GNU General Public License as published by
- the Free Software Foundation; either version 2 of the License, or
- (at your option) any later version.
-
- This program is distributed in the hope that it will be useful,
- but WITHOUT ANY WARRANTY; without even the implied warranty of
- MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
- GNU General Public License for more details.
-
- You should have received a copy of the GNU General Public License
- along with this program; if not, write to the Free Software
- Foundation, Inc., 59 Temple Place - Suite 330,
- Boston, MA 02111-1307, USA.
-
- Also add information on how to contact you by electronic and paper
-mail.
-
- If the program is interactive, make it output a short notice like
-this when it starts in an interactive mode:
-
- Gnomovision version 69, Copyright (C) YEAR NAME OF AUTHOR
- Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
- type `show w'.
- This is free software, and you are welcome to redistribute it
- under certain conditions; type `show c' for details.
-
- The hypothetical commands `show w' and `show c' should show the
-appropriate parts of the General Public License. Of course, the
-commands you use may be called something other than `show w' and `show
-c'; they could even be mouse-clicks or menu items--whatever suits your
-program.
-
- You should also get your employer (if you work as a programmer) or
-your school, if any, to sign a "copyright disclaimer" for the program,
-if necessary. Here is a sample; alter the names:
-
- Yoyodyne, Inc., hereby disclaims all copyright interest in the program
- `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
- SIGNATURE OF TY COON, 1 April 1989
- Ty Coon, President of Vice
-
- This General Public License does not permit incorporating your
-program into proprietary programs. If your program is a subroutine
-library, you may consider it more useful to permit linking proprietary
-applications with the library. If this is what you want to do, use the
-GNU Library General Public License instead of this License.

- Version 1.1, March 2000
- Copyright (C) 2000 Free Software Foundation, Inc.
- 59 Temple Place, Suite 330, Boston, MA 02111-1307, USA
-
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
- 0. PREAMBLE
-
- The purpose of this License is to make a manual, textbook, or other
- written document "free" in the sense of freedom: to assure everyone
- the effective freedom to copy and redistribute it, with or without
- modifying it, either commercially or noncommercially. Secondarily,
- this License preserves for the author and publisher a way to get
- credit for their work, while not being considered responsible for
- modifications made by others.
-
- This License is a kind of "copyleft", which means that derivative
- works of the document must themselves be free in the same sense.
- It complements the GNU General Public License, which is a copyleft
- license designed for free software.
-
- We have designed this License in order to use it for manuals for
- free software, because free software needs free documentation: a
- free program should come with manuals providing the same freedoms
- that the software does. But this License is not limited to
- software manuals; it can be used for any textual work, regardless
- of subject matter or whether it is published as a printed book.
- We recommend this License principally for works whose purpose is
- instruction or reference.
-
- 1. APPLICABILITY AND DEFINITIONS
-
- This License applies to any manual or other work that contains a
- notice placed by the copyright holder saying it can be distributed
- under the terms of this License. The "Document", below, refers to
- any such manual or work. Any member of the public is a licensee,
- and is addressed as "you".
-
- A "Modified Version" of the Document means any work containing the
- Document or a portion of it, either copied verbatim, or with
- modifications and/or translated into another language.
-
- A "Secondary Section" is a named appendix or a front-matter
- section of the Document that deals exclusively with the
- relationship of the publishers or authors of the Document to the
- Document's overall subject (or to related matters) and contains
- nothing that could fall directly within that overall subject.
- (For example, if the Document is in part a textbook of
- mathematics, a Secondary Section may not explain any mathematics.)
- The relationship could be a matter of historical connection with
- the subject or with related matters, or of legal, commercial,
- philosophical, ethical or political position regarding them.
-
- The "Invariant Sections" are certain Secondary Sections whose
- titles are designated, as being those of Invariant Sections, in
- the notice that says that the Document is released under this
- License.
-
- The "Cover Texts" are certain short passages of text that are
- listed, as Front-Cover Texts or Back-Cover Texts, in the notice
- that says that the Document is released under this License.
-
- A "Transparent" copy of the Document means a machine-readable copy,
- represented in a format whose specification is available to the
- general public, whose contents can be viewed and edited directly
- and straightforwardly with generic text editors or (for images
- composed of pixels) generic paint programs or (for drawings) some
- widely available drawing editor, and that is suitable for input to
- text formatters or for automatic translation to a variety of
- formats suitable for input to text formatters. A copy made in an
- otherwise Transparent file format whose markup has been designed
- to thwart or discourage subsequent modification by readers is not
- Transparent. A copy that is not "Transparent" is called "Opaque".
-
- Examples of suitable formats for Transparent copies include plain
- ASCII without markup, Texinfo input format, LaTeX input format,
- SGML or XML using a publicly available DTD, and
- standard-conforming simple HTML designed for human modification.
- Opaque formats include PostScript, PDF, proprietary formats that
- can be read and edited only by proprietary word processors, SGML
- or XML for which the DTD and/or processing tools are not generally
- available, and the machine-generated HTML produced by some word
- processors for output purposes only.
-
- The "Title Page" means, for a printed book, the title page itself,
- plus such following pages as are needed to hold, legibly, the
- material this License requires to appear in the title page. For
- works in formats which do not have any title page as such, "Title
- Page" means the text near the most prominent appearance of the
- work's title, preceding the beginning of the body of the text.
-
- 2. VERBATIM COPYING
-
- You may copy and distribute the Document in any medium, either
- commercially or noncommercially, provided that this License, the
- copyright notices, and the license notice saying this License
- applies to the Document are reproduced in all copies, and that you
- add no other conditions whatsoever to those of this License. You
- may not use technical measures to obstruct or control the reading
- or further copying of the copies you make or distribute. However,
- you may accept compensation in exchange for copies. If you
- distribute a large enough number of copies you must also follow
- the conditions in section 3.
-
- You may also lend copies, under the same conditions stated above,
- and you may publicly display copies.
-
- 3. COPYING IN QUANTITY
-
- If you publish printed copies of the Document numbering more than
- 100, and the Document's license notice requires Cover Texts, you
- must enclose the copies in covers that carry, clearly and legibly,
- all these Cover Texts: Front-Cover Texts on the front cover, and
- Back-Cover Texts on the back cover. Both covers must also clearly
- and legibly identify you as the publisher of these copies. The
- front cover must present the full title with all words of the
- title equally prominent and visible. You may add other material
- on the covers in addition. Copying with changes limited to the
- covers, as long as they preserve the title of the Document and
- satisfy these conditions, can be treated as verbatim copying in
- other respects.
-
- If the required texts for either cover are too voluminous to fit
- legibly, you should put the first ones listed (as many as fit
- reasonably) on the actual cover, and continue the rest onto
- adjacent pages.
-
- If you publish or distribute Opaque copies of the Document
- numbering more than 100, you must either include a
- machine-readable Transparent copy along with each Opaque copy, or
- state in or with each Opaque copy a publicly-accessible
- computer-network location containing a complete Transparent copy
- of the Document, free of added material, which the general
- network-using public has access to download anonymously at no
- charge using public-standard network protocols. If you use the
- latter option, you must take reasonably prudent steps, when you
- begin distribution of Opaque copies in quantity, to ensure that
- this Transparent copy will remain thus accessible at the stated
- location until at least one year after the last time you
- distribute an Opaque copy (directly or through your agents or
- retailers) of that edition to the public.
-
- It is requested, but not required, that you contact the authors of
- the Document well before redistributing any large number of
- copies, to give them a chance to provide you with an updated
- version of the Document.
-
- 4. MODIFICATIONS
-
- You may copy and distribute a Modified Version of the Document
- under the conditions of sections 2 and 3 above, provided that you
- release the Modified Version under precisely this License, with
- the Modified Version filling the role of the Document, thus
- licensing distribution and modification of the Modified Version to
- whoever possesses a copy of it. In addition, you must do these
- things in the Modified Version:
-
- A. Use in the Title Page (and on the covers, if any) a title
- distinct from that of the Document, and from those of
- previous versions (which should, if there were any, be listed
- in the History section of the Document). You may use the
- same title as a previous version if the original publisher of
- that version gives permission.
-
- B. List on the Title Page, as authors, one or more persons or
- entities responsible for authorship of the modifications in
- the Modified Version, together with at least five of the
- principal authors of the Document (all of its principal
- authors, if it has less than five).
-
- C. State on the Title page the name of the publisher of the
- Modified Version, as the publisher.
-
- D. Preserve all the copyright notices of the Document.
-
- E. Add an appropriate copyright notice for your modifications
- adjacent to the other copyright notices.
-
- F. Include, immediately after the copyright notices, a license
- notice giving the public permission to use the Modified
- Version under the terms of this License, in the form shown in
- the Addendum below.
-
- G. Preserve in that license notice the full lists of Invariant
- Sections and required Cover Texts given in the Document's
- license notice.
-
- H. Include an unaltered copy of this License.
-
- I. Preserve the section entitled "History", and its title, and
- add to it an item stating at least the title, year, new
- authors, and publisher of the Modified Version as given on
- the Title Page. If there is no section entitled "History" in
- the Document, create one stating the title, year, authors,
- and publisher of the Document as given on its Title Page,
- then add an item describing the Modified Version as stated in
- the previous sentence.
-
- J. Preserve the network location, if any, given in the Document
- for public access to a Transparent copy of the Document, and
- likewise the network locations given in the Document for
- previous versions it was based on. These may be placed in
- the "History" section. You may omit a network location for a
- work that was published at least four years before the
- Document itself, or if the original publisher of the version
- it refers to gives permission.
-
- K. In any section entitled "Acknowledgments" or "Dedications",
- preserve the section's title, and preserve in the section all
- the substance and tone of each of the contributor
- acknowledgments and/or dedications given therein.
-
- L. Preserve all the Invariant Sections of the Document,
- unaltered in their text and in their titles. Section numbers
- or the equivalent are not considered part of the section
- titles.
-
- M. Delete any section entitled "Endorsements". Such a section
- may not be included in the Modified Version.
-
- N. Do not retitle any existing section as "Endorsements" or to
- conflict in title with any Invariant Section.
-
- If the Modified Version includes new front-matter sections or
- appendices that qualify as Secondary Sections and contain no
- material copied from the Document, you may at your option
- designate some or all of these sections as invariant. To do this,
- add their titles to the list of Invariant Sections in the Modified
- Version's license notice. These titles must be distinct from any
- other section titles.
-
- You may add a section entitled "Endorsements", provided it contains
- nothing but endorsements of your Modified Version by various
- parties--for example, statements of peer review or that the text
- has been approved by an organization as the authoritative
- definition of a standard.
-
- You may add a passage of up to five words as a Front-Cover Text,
- and a passage of up to 25 words as a Back-Cover Text, to the end
- of the list of Cover Texts in the Modified Version. Only one
- passage of Front-Cover Text and one of Back-Cover Text may be
- added by (or through arrangements made by) any one entity. If the
- Document already includes a cover text for the same cover,
- previously added by you or by arrangement made by the same entity
- you are acting on behalf of, you may not add another; but you may
- replace the old one, on explicit permission from the previous
- publisher that added the old one.
-
- The author(s) and publisher(s) of the Document do not by this
- License give permission to use their names for publicity for or to
- assert or imply endorsement of any Modified Version.
-
- 5. COMBINING DOCUMENTS
-
- You may combine the Document with other documents released under
- this License, under the terms defined in section 4 above for
- modified versions, provided that you include in the combination
- all of the Invariant Sections of all of the original documents,
- unmodified, and list them all as Invariant Sections of your
- combined work in its license notice.
-
- The combined work need only contain one copy of this License, and
- multiple identical Invariant Sections may be replaced with a single
- copy. If there are multiple Invariant Sections with the same name
- but different contents, make the title of each such section unique
- by adding at the end of it, in parentheses, the name of the
- original author or publisher of that section if known, or else a
- unique number. Make the same adjustment to the section titles in
- the list of Invariant Sections in the license notice of the
- combined work.
-
- In the combination, you must combine any sections entitled
- "History" in the various original documents, forming one section
- entitled "History"; likewise combine any sections entitled
- "Acknowledgments", and any sections entitled "Dedications". You
- must delete all sections entitled "Endorsements."
-
- 6. COLLECTIONS OF DOCUMENTS
-
- You may make a collection consisting of the Document and other
- documents released under this License, and replace the individual
- copies of this License in the various documents with a single copy
- that is included in the collection, provided that you follow the
- rules of this License for verbatim copying of each of the
- documents in all other respects.
-
- You may extract a single document from such a collection, and
- distribute it individually under this License, provided you insert
- a copy of this License into the extracted document, and follow
- this License in all other respects regarding verbatim copying of
- that document.
-
- 7. AGGREGATION WITH INDEPENDENT WORKS
-
- A compilation of the Document or its derivatives with other
- separate and independent documents or works, in or on a volume of
- a storage or distribution medium, does not as a whole count as a
- Modified Version of the Document, provided no compilation
- copyright is claimed for the compilation. Such a compilation is
- called an "aggregate", and this License does not apply to the
- other self-contained works thus compiled with the Document, on
- account of their being thus compiled, if they are not themselves
- derivative works of the Document.
-
- If the Cover Text requirement of section 3 is applicable to these
- copies of the Document, then if the Document is less than one
- quarter of the entire aggregate, the Document's Cover Texts may be
- placed on covers that surround only the Document within the
- aggregate. Otherwise they must appear on covers around the whole
- aggregate.
-
- 8. TRANSLATION
-
- Translation is considered a kind of modification, so you may
- distribute translations of the Document under the terms of section
- 4. Replacing Invariant Sections with translations requires special
- permission from their copyright holders, but you may include
- translations of some or all Invariant Sections in addition to the
- original versions of these Invariant Sections. You may include a
- translation of this License provided that you also include the
- original English version of this License. In case of a
- disagreement between the translation and the original English
- version of this License, the original English version will prevail.
-
- 9. TERMINATION
-
- You may not copy, modify, sublicense, or distribute the Document
- except as expressly provided for under this License. Any other
- attempt to copy, modify, sublicense or distribute the Document is
- void, and will automatically terminate your rights under this
- License. However, parties who have received copies, or rights,
- from you under this License will not have their licenses
- terminated so long as such parties remain in full compliance.
-
- 10. FUTURE REVISIONS OF THIS LICENSE
-
- The Free Software Foundation may publish new, revised versions of
- the GNU Free Documentation License from time to time. Such new
- versions will be similar in spirit to the present version, but may
- differ in detail to address new problems or concerns. See
- `http://www.gnu.org/copyleft/'.
-
- Each version of the License is given a distinguishing version
- number. If the Document specifies that a particular numbered
- version of this License "or any later version" applies to it, you
- have the option of following the terms and conditions either of
- that specified version or of any later version that has been
- published (not as a draft) by the Free Software Foundation. If
- the Document does not specify a version number of this License,
- you may choose any version ever published (not as a draft) by the
- Free Software Foundation.
-
-ADDENDUM: How to use this License for your documents
-====================================================
-
- To use this License in a document you have written, include a copy of
-the License in the document and put the following copyright and license
-notices just after the title page:
-
- Copyright (C) YEAR YOUR NAME.
- Permission is granted to copy, distribute and/or modify this document
- under the terms of the GNU Free Documentation License, Version 1.1
- or any later version published by the Free Software Foundation;
- with the Invariant Sections being LIST THEIR TITLES, with the
- Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
- A copy of the license is included in the section entitled ``GNU
- Free Documentation License''.
-
- If you have no Invariant Sections, write "with no Invariant Sections"
-instead of saying which ones are invariant. If you have no Front-Cover
-Texts, write "no Front-Cover Texts" instead of "Front-Cover Texts being
-LIST"; likewise for Back-Cover Texts.
-
- If your document contains nontrivial examples of program code, we
-recommend releasing these examples in parallel under your choice of
-free software license, such as the GNU General Public License, to
-permit their use in free software.
