If the required texts for either cover are too voluminous to t legibly, you should put the rst ones listed (as many as t reasonably) on the actual cover,
and continue the rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering more than 100, you must either include a machine-readable Transparent copy
along with each Opaque copy, or state in or with each Opaque copy a computer-network location from which the general network-using public has access
to download using public-standard network protocols a complete Transparent copy of the Document, free of added material. If you use the latter option,
you must take reasonably prudent steps, when you begin distribution of Opaque copies in quantity, to ensure that this Transparent copy will remain thus
accessible at the stated location until at least one year after the last time you distribute an Opaque copy (directly or through your agents or retailers) of
that edition to the public.
It is requested, but not required, that you contact the authors of the Document well before redistributing any large number of copies, to give them a
chance to provide you with an updated version of the Document.
MODIFICATIONS
You may copy and distribute a Modied Version of the Document under the conditions of sections 2 and 3 above, provided that you release the Modied
Version under precisely this License, with the Modied Version lling the role of the Document, thus licensing distribution and modication of the
Modied Version to whoever possesses a copy of it. In addition, you must do these things in the Modied Version:
A. 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.
B. List on the Title Page, as authors, one or more persons or entities responsible for authorship of the modications in the Modied Version, together
with at least ve of the principal authors of the Document (all of its principal authors, if it has fewer than ve), unless they release you from this require-
ment.
C. State on the Title page the name of the publisher of the Modied Version, as the publisher.
D. Preserve all the copyright notices of the Document.
E. Add an appropriate copyright notice for your modications adjacent to the other copyright notices.
F. Include, immediately after the copyright notices, a license notice giving the public permission to use the Modied Version under the terms of this
License, in the form shown in the Addendum below.
G. Preserve in that license notice the full lists of Invariant Sections and required Cover Texts given in the Document’s license notice.
H. Include an unaltered copy of this License.
I. 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
Modied 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 Modied 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 published 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 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.
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 Modied Version.
N. Do not retitle any existing section to be Entitled “Endorsements” or to conict in title with any Invariant Section.
O. Preserve any Warranty Disclaimers.
If the Modied 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
Modied 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 Modied Version by various parties--for example,
statements of peer review or that the text has been approved by an organization as the authoritative denition of a standard.
You may add a passage of up to ve 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 Modied 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.
