D.2. 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.
