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.
