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. If a section does not fit the above definition of Secondary then it is not
allowed to be designated as Invariant. The Document may contain zero Invariant Sections.
If the Document does not identify any Invariant Sections then there are none.
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 Front-Cover Text may be at most 5 words, and a Back-Cover Text may be at
most 25 words.
A "Transparent" copy of the Document means a machine-readable copy, represented in a
format whose specification is available to the general public, that is suitable for revisingthe
document 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, or absence of markup, has been arranged to thwart or discourage
subsequent modification by readers is not Transparent. An image format is not Transparent
if used for any substantial amount of text. 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, PostScript or PDF designed for human
modification. Examples of transparent image formats include PNG, XCF and JPG. Opaque
formats include 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, PostScript or PDF 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.
A section "Entitled XYZ" means a named subunit of the Document whose title either is
precisely XYZ or contains XYZ in parentheses following text that translates XYZ in another
language. (Here XYZ stands for a specific section name mentioned below, such as
"Acknowledgements", "Dedications", "Endorsements", or "History".) To "Preserve the Title"
of such a section when you modify the Document means that it remains a section "Entitled
XYZ" according to this definition.
The Document may include Warranty Disclaimers next to the notice which states that this
License applies to the Document. These Warranty Disclaimers are considered to be
included by reference in this License, but only as regards disclaiming warranties: any other
implication that these Warranty Disclaimers may have is void and has no effect on the
meaning of this License.
