You may copy and distribute a Modified Version of the Document +under the conditions of sections 2 and 3 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.
