Hi Nicolas,

Nicolas Graves <ngraves@ngraves.fr> skribis:

> Factor out wrapper make-nerd-dictation-package.
> Add package variants :

> - nerd-dictation/sox-xdotool
> - nerd-dictation/sox-ydotool

Applied with the changes below (using ‘with-imported-modules’ instead of
passing #:modules, and #$output instead of the now-deprecated
‘%output’).

I also tweaked the commit log according to our conventions.

Thank you,
Ludo’.
