Oh! I hadn't fully absorbed the following, but it seems then that rms believes that the restriction like that on the Emacs manual (that you must redistribute certain extraneous pieces) does not violate freedom 3 of the FSF's Free Software Definition: * The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this. (whether or not the work in question is documentation), while I believe the Debian people decided early in the discussion that a similar restriction on software would violate point 3 of the DFSG: 3. Derived Works The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software. Actually, I'm a little unclear on the latter point. To what extent are non-functional restrictions OK for Debian? For instance, the GPL's clause 2c (message at an interactive prompt) is uncontroversial, but the much longer message that the reiserfs utilities printed seemed to be more questionable (if it were required by the license, and aside from the fact that it was incompatible with the GPL). Or is the question whether the restrictions in the GFDL are truly non-functional? (I note that FSF's freedom 3 is more focussed on improving the program, i.e., functionality, while DFSG 3 is stated more broadly.) Peace, Dylan Thurston
