The suggestion that a .ly file would somehow be a derivative work of lilypond is ridiculous. Writing a C++ to be compiled with gcc does not constitute a derivate work of gcc. Writing an html file to be displayed in Firefox does not consistute a derivative work of firefox. Creating graphics in GIMP does not constitute a derivative work of gimp. etc. articulate.ly is a 668-line .ly file containing a bunch of scheme. It is absolutely not a derivative work of lilypond. > I strongly suggest not distributing it with the rest of > Lilypond since any "crosspollination", namely people using the code, its > structure, documentation and whatever else will constitute a licensing > violation of Peter's and his empoyer's licensing choice. The documentation was written by Francisco. I agree that this could cause a problem if anybody (other than Peter or a NICTA employee) ever tried to "port" these functions into a Performer. > Since that is an accident waiting to happen even if inclusion of > articulate.ly could conceivably count as "mere aggregation", we need to > steer clear. articulate.ly is an optional include. It's less "aggrevated" than the "public domain" snippets which we include in the manual. I can't imagine how anything that we (potentially) distribute could be more "mere aggrevation" than articulate.ly. > Any other GPLvx.0 only (where x includes 3) bombs waiting to happen in > the Lilypond code base? A few quick greps suggests that we have some "2.0 or later" stuff, which isn't a problem. texinfo.tex, the big contender in my mind for 2.0, is 3.0 or later.
