Can someone remind me how exactly the license above is incompatible with the GNU GPL? Material under this license seems as miscible with a work under the GNU GPL as materials under the 2- or 3-clause BSD licenses are. > I intend to make the effort some day, but first I have to finish GPL > version 3, which faces other difficult questions. Until that time, perhaps you could encourage authors to dual-license their documentation under the GNU GPL and the GNU FDL. Thanks for making the statement you have, though I must point out that while your message offered some insight into the "Copying in Quantity" section of the GNU FDL, and why an analogue to the GPL's requirement to distribute source code has been weakened, it did not address why Invariant Sections, Cover Texts, Acknowledgements, or Endorsements make the GNU FDL more appealing to publishers than the GNU GPL is. -- G.
