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.
