@Claes Wallin (韋嘉誠) So actually, I was wrong before, and Guix could do the things that npm does, where each package has its own sub-packages... probably. But it would be dumb and tedious and one might want to claw one's eyes out by the end of it.

Anyway, the guile that will be built and included with emacs here will be built specifically for the purposes of building this emacs. It won't be the main guile used with other programs, though you could access it if you wanted to.
