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.
