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,

containing the Document or a portion of it, either copied

> A <SPAN
CLASS="QUOTE"
>"Secondary Section"</SPAN

front-matter section of the <A

>Document</A

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.

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 <SPAN

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

machine-generated HTML produced by some word processors for
output purposes only.
