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:
</p>
<div class="orderedlist">
<a id="gfdl-modif-cond"></a>
<p class="title">
<b></b>
</p>
<ol type="A">
<li>
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.
</li>
<li>
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.
</li>
<li>
State on the Title page the name of the publisher of the Modified
Version, as the publisher.
</li>
<li>
Preserve all the copyright notices of the Document.
</li>
<li>
Add an appropriate copyright notice for your
modifications adjacent to the other copyright notices.
</li>
<li>
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 <a href="apas12.html" title="12. 
ADDENDUM: How to use this License for your documents
">Addendum</a> below.
</li>
<li>
Preserve in that license notice the full lists of Invariant
Sections and required Cover Texts given in the Document's license
notice.
</li>
<li>
Include an unaltered copy of this License.
</li>
<li>
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.
</li>
<li>
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.
</li>
<li>
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.
</li>
<li>
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.
</li>
<li>
Delete any section Entitled "Endorsements". Such a section may
not be included in the Modified Version.
</li>
<li>
Do not retitle any existing section to be Entitled "Endorsements"
or to conflict in title with any Invariant Section.
</li>
<li>
Preserve any Warranty Disclaimers.
</li>
</ol>
</div>
<p>
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.
</p>
<p>
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.
</p>
<p>
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.
