<para>The purpose of this License is to make a manual, textbook, or other
|
|
functional and useful document "free" in the sense of freedom: to assure
|
|
everyone the effective freedom to copy and redistribute it, with or
|
|
without modifying it, either commercially or noncommercially. Secondarily,
|
|
this License preserves for the author and publisher a way to get credit
|

for their work, while not being considered responsible for modifications
|

made by others.</para>

|
|
<para>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.</para>
|
|
|
|
<para>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.</para>

grants a world-wide, royalty-free license, unlimited in duration, to use

that work under the conditions stated herein. The "Document", below,

refers to any such manual or work. Any member of the public is a licensee,

<para id="gfdl-secnd-sect">A "Secondary Section" is a named appendix or a

front-matter section of the Document that deals exclusively with the

relationship of the publishers or authors of the Document to the

|
Document's overall subject (or to related matters) and contains nothing
|

that could fall directly within that overall subject. (Thus, if the

|
Document is in part a textbook of mathematics, a Secondary Section may not
|
|
explain any mathematics.) The relationship could be a matter of historical
|

connection with the subject or with related matters, or of legal,
|
|
commercial, philosophical, ethical or political position regarding
|
|
them.</para>

it is not allowed to be designated as Invariant. The Document may contain

zero Invariant Sections. If the Document does not identify any Invariant

for input to text formatters. A copy made in an otherwise Transparent file

format whose markup, or absence of markup, has been arranged to thwart or

discourage subsequent modification by readers is not Transparent. An image

PostScript or PDF designed for human modification. Examples of transparent

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

For works in formats which do not have any title page as such, "Title

<title>COPYING IN QUANTITY</title>

|
|
<para>If you publish printed copies (or copies in media that commonly have
|
|
printed covers) of the Document, numbering more than 100, and the
|
|
Document's license notice requires Cover Texts, you must enclose the
|
|
copies in covers that carry, clearly and legibly, all these Cover Texts:
|
|
Front-Cover Texts on the front cover, and Back-Cover Texts on the back
|
|
cover. Both covers must also clearly and legibly identify you as the
|
|
publisher of these copies. The front cover must present the full title
|
|
with all words of the title equally prominent and visible. You may add
|
|
other material on the covers in addition. Copying with changes limited to
|
|
the covers, as long as they preserve the title of the Document and satisfy
|
|
these conditions, can be treated as verbatim copying in other
|
|
respects.</para>
|
|
|
|
<para>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.</para>
|
|
|
|
<para>If you publish or distribute Opaque copies of the Document numbering
|
|
more than 100, you must either include a machine-readable Transparent copy
|
|
along with each Opaque copy, or state in or with each Opaque copy a
|
|
computer-network location from which the general network-using public has
|
|
access to download using public-standard network protocols a complete
|
|
Transparent copy of the Document, free of added material. If you use the
|
|
latter option, you must take reasonably prudent steps, when you begin
|
|
distribution of Opaque copies in quantity, to ensure that this Transparent
|
|
copy will remain thus accessible at the stated location until at least one
|
|
year after the last time you distribute an Opaque copy (directly or
|
|
through your agents or retailers) of that edition to the public.</para>

<para>It is requested, but not required, that you contact the authors of
