of it. In addition, you must do these things in the Modified 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 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.
    * C. State on the Title page the name of the publisher of the
      Modified Version, as the publisher.
    * D. Preserve all the copyright notices of the Document.
    * E. Add an appropriate copyright notice for your modifications
      adjacent to the other copyright notices.
    * F. 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.
    * 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 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.
    * 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 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 permission to use their names for publicity for or to assert or
imply endorsement of any Modified Version.

5. COMBINING DOCUMENTS

You may combine the Document with other documents released under this
License, under the terms defined in section 4 above for modified
versions, provided that you include in the combination all of the
Invariant Sections of all of the original documents, unmodified, and
list them all as Invariant Sections of your combined work in its
license notice, and that you preserve all their Warranty Disclaimers.

The combined work need only contain one copy of this License, and
multiple identical Invariant Sections may be replaced with a single
copy. If there are multiple Invariant Sections with the same name but
different contents, make the title of each such section unique by
adding at the end of it, in parentheses, the name of the original
author or publisher of that section if known, or else a unique number.
Make the same adjustment to the section titles in the list of
Invariant Sections in the license notice of the combined work.

In the combination, you must combine any sections Entitled "History"
in the various original documents, forming one section Entitled
"History"; likewise combine any sections Entitled "Acknowledgements",
and any sections Entitled "Dedications". You must delete all sections
Entitled "Endorsements."

6. COLLECTIONS OF DOCUMENTS

You may make a collection consisting of the Document and other
documents released under this License, and replace the individual
copies of this License in the various documents with a single copy
that is included in the collection, provided that you follow the rules
of this License for verbatim copying of each of the documents in all
other respects.

You may extract a single document from such a collection, and
distribute it individually under this License, provided you insert a
copy of this License into the extracted document, and follow this
License in all other respects regarding verbatim copying of that
document.

7. AGGREGATION WITH INDEPENDENT WORKS

A compilation of the Document or its derivatives with other separate
and independent documents or works, in or on a volume of a storage or
distribution medium, is called an "aggregate" if the copyright
resulting from the compilation is not used to limit the legal rights
of the compilation's users beyond what the individual works permit.
When the Document is included in an aggregate, this License does not
apply to the other works in the aggregate which are not themselves
derivative works of the Document.

If the Cover Text requirement of section 3 is applicable to these
copies of the Document, then if the Document is less than one half of
the entire aggregate, the Document's Cover Texts may be placed on
covers that bracket the Document within the aggregate, or the
electronic equivalent of covers if the Document is in electronic form.
Otherwise they must appear on printed covers that bracket the whole
aggregate.

8. TRANSLATION

Translation is considered a kind of modification, so you may
distribute translations of the Document under the terms of section 4.
Replacing Invariant Sections with translations requires special
permission from their copyright holders, but you may include
translations of some or all Invariant Sections in addition to the
original versions of these Invariant Sections. You may include a
translation of this License, and all the license notices in the
Document, and any Warranty Disclaimers, provided that you also include
the original English version of this License and the original versions
of those notices and disclaimers. In case of a disagreement between
the translation and the original version of this License or a notice
or disclaimer, the original version will prevail.

If a section in the Document is Entitled "Acknowledgements",
"Dedications", or "History", the requirement (section 4) to Preserve
its Title (section 1) will typically require changing the actual
title.

9. TERMINATION

You may not copy, modify, sublicense, or distribute the Document
except as expressly provided for under this License. Any other attempt
to copy, modify, sublicense or distribute the Document is void, and
will automatically terminate your rights under this License. However,
parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such
parties remain in full compliance.

10. FUTURE REVISIONS OF THIS LICENSE

The Free Software Foundation may publish new, revised versions of the
GNU Free Documentation License from time to time. Such new versions
will be similar in spirit to the present version, but may differ in
detail to address new problems or concerns. See
http://www.gnu.org/copyleft/.

Each version of the License is given a distinguishing version number.
If the Document specifies that a particular numbered version of this
License "or any later version" applies to it, you have the option of
following the terms and conditions either of that specified version or
of any later version that has been published (not as a draft) by the
Free Software Foundation. If the Document does not specify a version
number of this License, you may choose any version ever published (not
as a draft) by the Free Software Foundation.
