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.
