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 less than + five).
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", and 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.
In any section entitled + "Acknowledgements" or "Dedications", preserve the section's + title, 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 as "Endorsements" or to conflict in title with + any Invariant Section.
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.
