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 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 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.
