You may copy and distribute a Modified Version of the Document under the
conditions of sections 3 and 4 above, provided that you release the
Modified Version under precisely this License, with the Modified Version
filling the role of the Document, thus licensing distribution and
modification of the Modified Version to whoever possesses a copy of it.
In addition, you must do these things in the Modified Version:
-
Use in the Title Page (and on the covers, if any) a title distinct
from that of the Document, and from those of previous versions
(which should, if there were any, be listed in the History section
of the Document). You may use the same title as a previous version
if the original publisher of that version gives permission.
-
List on the Title Page, as authors, one or more persons or entities
responsible for authorship of the modifications in the Modified
Version, together with at least five of the principal authors of the
Document (all of its principal authors, if it has fewer than five),
unless they release you from this requirement.
-
State on the Title page the name of the publisher of the Modified
Version, as the publisher.
- Preserve all the copyright notices of the Document.
-
Add an appropriate copyright notice for your modifications adjacent
to the other copyright notices.
-
Include, immediately after the copyright notices, a license notice
giving the public permission to use the Modified Version under the
terms of this License, in the form shown in the
Addendum
below.
-
Preserve in that license notice the full lists of Invariant Sections
and required Cover Texts given in the Document's license notice.
- Include an unaltered copy of this License.
-
Preserve the section Entitled «History»,
Preserve its Title, and add to it an item stating at least the
title, year, new authors, and publisher of the Modified Version as
given on the Title Page. If there is no section Entitled
«History»
in the Document, create one stating the title, year, authors, and
publisher of the Document as given on its Title Page, then add an
item describing the Modified Version as stated in the previous
sentence.
-
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
published at least four years before the Document itself, or if the
original publisher of the version it refers to gives permission.
-
For any section Entitled
«Acknowledgements» or «Dedications»,
Preserve the Title of the section, and preserve in the section all
the substance and tone of each of the contributor acknowledgements
and/or dedications given therein.
-
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.
-
Delete any section Entitled «Endorsements».
Such a section may not be included in the Modified Version.
-
Do not retitle any existing section to be Entitled
«Endorsements»
or to conflict in title with any Invariant Section.
- 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 permission to use their names for publicity for or to assert or
imply endorsement of any Modified Version.
