Appendix C: Copying this Manual
3. COPYING IN QUANTITY
If you publish printed copies (or copies in media that commonly have printed covers) of the
Document, numbering more than 100, and the Document’s license notice requires Cover
Texts, you must enclose the copies in covers that carry, clearly and legibly, all these Cover
Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the back cover. Both
covers must also clearly and legibly identify you as the publisher of these copies. The front
cover must present the full title with all words of the title equally prominent and visible.
You may add other material on the covers in addition. Copying with changes limited to
the covers, as long as they preserve the title of the Document and satisfy these conditions,
can be treated as verbatim copying in other respects.
If the required texts for either cover are too voluminous to ﬁt legibly, you should put the
ﬁrst ones listed (as many as ﬁt reasonably) on the actual cover, and continue the rest onto
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.
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:
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 sectionof 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
D. Preserve all the copyright notices of the Document.
E. Add an appropriate copyright notice for your modiﬁcations adjacent to the other copy-
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.
