-;;; Commentary:
-;;
-;; # Usage
-;;
-;; Put perfect-margin under your Emacs load path, and add this to your init.el
-;;
-;; (require 'perfect-margin)
-;;
-;; Use `M-x perfect-margin-mode` to turn on/off perfect-margin.
-;;
-;; To make it permanent add this to your init.el after require.
-;;
-;; (perfect-margin-mode 1)
-;;
-;; Note: when using together with minimap or linum, make sure you place config for perfect-margin *AFTER* minimap and linum.
-;;
-;; # Customization
-;;
-;; Via `M-x customize-group` and enter perfect-margin.
-;;
-;; Change `perfect-margin-visible-width` and `Apply and Save`. That's it.
-;;
-;; *Or* you can change the visible window width by setup `perfect-margin-visible-width` on the init.el.
-;;
-;; (setq perfect-margin-visible-width 128)
-;;
-;; # Additional binding on margin area
-;;
-;; You can place this in your init.el to make mouse wheel scroll on margin area just like it scroll on the visible window.
-;;
-;; (dolist (margin '("<left-margin> " "<right-margin> "))
-;;   (global-set-key (kbd (concat margin "<mouse-1>")) 'ignore)
-;;   (global-set-key (kbd (concat margin "<mouse-3>")) 'ignore)
-;;   (dolist (multiple '("" "double-" "triple-"))
-;;     (global-set-key (kbd (concat margin "<" multiple "wheel-up>")) 'mwheel-scroll)
-;;     (global-set-key (kbd (concat margin "<" multiple "wheel-down>")) 'mwheel-scroll)))
