as given on its Title Page, then add an item describing the Modified Version as
stated in the previous sentence.
J. Preserve the network location, if any, given in the Document for public access to
a Transparent copy of the Document, and likewise the network locations given
in the Document for previous versions it was based on. These may be placed in
the ”History” section. You may omit a network location for a work that was pub-
lished at least four years before the Document itself, or if the original publisher of
the version it refers to gives permission.
K. For any section Entitled ”Acknowledgements” or ”Dedications”, Preserve the Ti-
tle of the section, and preserve in the section all the substance and tone of each of
the contributor acknowledgements and/or dedications given therein.
L. Preserve all the Invariant Sections of the Document, unaltered in their text and
in their titles. Section numbers or the equivalent are not considered part of the
section titles.
M. Delete any section Entitled ”Endorsements”. Such a section may not be included
in the Modified Version.
N. Do not retitle any existing section to be Entitled ”Endorsements” or to conflict in
title with any Invariant Section.
O. Preserve any Warranty Disclaimers.
If the Modified Version includes new front-matter sections or appendices that qualify
as Secondary Sections and contain no material copied from the Document, you may at
your option designate some or all of these sections as invariant. To do this, add their
titles to the list of Invariant Sections in the Modified Version’s license notice. These
titles must be distinct from any other section titles.
You may add a section Entitled ”Endorsements”, provided it contains nothing but
endorsements of your Modified Version by various parties–for example, statements of
peer review or that the text has been approved by an organization as the authoritative
definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage of up
to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified
Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be
added by (or through arrangements made by) any one entity. If the Document already
includes a cover text for the same cover, previously added by you or by arrangement
made by the same entity you are acting on behalf of, you may not add another; but you
may replace the old one, on explicit permission from the previous publisher that added
the old one.
The author(s) and publisher(s) of the Document do not by this License give permis-
sion to use their names for publicity for or to assert or imply endorsement of any Mod-
ified Version.
