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.
