> ;; Ex is implemented as an extensible minilanguage, whose grammar
> ;; is stored in `evil-ex-grammar'. Ex commands are defined with
> ;; `evil-ex-define-cmd', which creates a binding from a string
> ;; to an interactive function. It is also possible to define key
> ;; sequences which execute a command immediately when entered:
> ;; such shortcuts go in `evil-ex-map'.
