D.4. Copying in quantity
If you publish printed copies 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 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 publicly-accessible computer-network location
containing a complete Transparent copy of the Document, free of added material, which
the general network-using public has access to download anonymously at no charge using
public-standard network protocols. 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.
