So I don't specify > B and C in package requires section of > package A. "package B or (disjunction) package C" - does this mean you can't `require' both? Why not? Collisions? If so, the idea of the "require list as an option" strikes me as odd. Did you see it all over the MELPA world? Scary. Better: require both B and C. If you don't want to change the code all over the place in A (which also is possible), there are many workarounds that shouldn't be too slow, for example can you create a "function pool" and a bunch of variables in A to hold functions. When the user switches from B to C mode, or the other way around, the function pool reassigns the functions in effect in A. -- underground experts united .... http://user.it.uu.se/~embe8573 Emacs Gnus Blogomatic ......... http://user.it.uu.se/~embe8573/blogomatic - so far: 42 Blogomatic articles -
