;;; Commentary:
|
|
|
|
;; This package provides a minor mode for viewing books and novels, or anthing meant to be read
|
|
;; by humans. You can set line spacing, column width and face from the `article' custom group.
|
|
;; I recommend also setting a less annoying cursor color, since I haven't implemented it here.
