-;;; Commentary:
-
-;; Popwin makes you free from the hell of annoying buffers such like
-;; *Help*, *Completions*, *compilation*, and etc.
-;;
-;; To use popwin, just add the following code into your .emacs:
-;;
-;; (require 'popwin)
-;; (popwin-mode 1)
-;;
-;; Then try to show some buffer, for example *Help* or
-;; *Completeions*. Unlike standard behavior, their buffers may be
-;; shown in a popup window at the bottom of the frame. And you can
-;; close the popup window seamlessly by typing C-g or selecting other
-;; windows.
-;;
-;; `popwin:display-buffer' displays special buffers in a popup window
-;; and displays normal buffers as unsual. Special buffers are
-;; specified in `popwin:special-display-config', which tells popwin
-;; how to display such buffers. See docstring of
-;; `popwin:special-display-config' for more information.
-;;
-;; The default width/height/position of popup window can be changed by
-;; setting `popwin:popup-window-width', `popwin:popup-window-height',
-;; and `popwin:popup-window-position'. You can also change the
-;; behavior for a specific buffer. See docstring of
-;; `popwin:special-display-config'.
-;;
-;; If you want to use some useful commands such like
-;; `popwin:popup-buffer' and `popwin:find-file' easily. You may bind
-;; `popwin:keymap' to `C-z', for example, like:
-;;
-;; (global-set-key (kbd "C-z") popwin:keymap)
-;;
-;; See also `popwin:keymap' documentation.
-;;
-;; Enjoy!

- regexp: If the value is non-nil, PATTERN will be used as regexp
- to matching buffer.
-
- width, height: Specify width or height of the popup window. If
- no size specified, `popwin:popup-window-width' or
- `popwin:popup-window-height' will be used. See also position
- keyword.
-
- position: The value must be one of (left top right bottom). The
- popup window will shown at the position of the frame. If no
- position specified, `popwin:popup-window-position' will be
- used.
-
- noselect: If the value is non-nil, the popup window will not be
- selected when it is shown.
-
- dedicated: If the value is non-nil, the popup window will be
- dedicated to the original popup buffer. In this case, when
- another buffer is selected in the popup window, the popup
- window will be closed immedicately and the selected buffer
- will be shown on the previously selected window.
-
- stick: If the value is non-nil, the popup window will be stuck
- when it is shown.
-
- tail: If the value is non-nil, the popup window will show the
- last contents.
-
-Examples: With '(\"*scratch*\" :height 30 :position top),
-*scratch* buffer will be shown at the top of the frame with

+Minor mode for `popwin-mode'.
+
+This is a global minor mode. If called interactively, toggle the
+`Popwin mode' mode. If the prefix argument is positive, enable the
+mode, and if it is zero or negative, disable the mode.
+
+If called from Lisp, toggle the mode if ARG is `toggle'. Enable the
+mode if ARG is nil, omitted, or is a positive number. Disable the mode
+if ARG is a negative number.
+
+To check whether the minor mode is enabled in the current buffer,
+evaluate `(default-value \\='popwin-mode)'.
+
+The mode's hook is called both when the mode is enabled and when it is
+disabled.

+;;; Commentary:
+
+;; Popwin makes you free from the hell of annoying buffers such like
+;; *Help*, *Completions*, *compilation*, and etc.
+;;
+;; To use popwin, just add the following code into your .emacs:
+;;
+;; (require 'popwin)
+;; (popwin-mode 1)
+;;
+;; Then try to show some buffer, for example *Help* or
+;; *Completeions*. Unlike standard behavior, their buffers may be
+;; shown in a popup window at the bottom of the frame. And you can
+;; close the popup window seamlessly by typing C-g or selecting other
+;; windows.
+;;
+;; `popwin:display-buffer' displays special buffers in a popup window
+;; and displays normal buffers as unsual. Special buffers are
+;; specified in `popwin:special-display-config', which tells popwin
+;; how to display such buffers. See docstring of
+;; `popwin:special-display-config' for more information.
+;;
+;; The default width/height/position of popup window can be changed by
+;; setting `popwin:popup-window-width', `popwin:popup-window-height',
+;; and `popwin:popup-window-position'. You can also change the
+;; behavior for a specific buffer. See docstring of
+;; `popwin:special-display-config'.
+;;
+;; If you want to use some useful commands such like
+;; `popwin:popup-buffer' and `popwin:find-file' easily. You may bind
+;; `popwin:keymap' to `C-z', for example, like:
+;;
+;; (global-set-key (kbd "C-z") popwin:keymap)
+;;
+;; See also `popwin:keymap' documentation.
+;;
+;; Enjoy!

+symbol, PATTERN will be CONFIG and KEYWORDS will be
+empty. Available keywords are following:
+
+ regexp: If the value is non-nil, PATTERN will be used as regexp
+ to matching buffer.
+
+ width, height: Specify width or height of the popup window. If
+ no size specified, `popwin:popup-window-width' or
+ `popwin:popup-window-height' will be used. See also position
+ keyword.
+
+ position: The value must be one of (left top right bottom). The
+ popup window will shown at the position of the frame. If no
+ position specified, `popwin:popup-window-position' will be
+ used.
+
+ noselect: If the value is non-nil, the popup window will not be
+ selected when it is shown.
+
+ dedicated: If the value is non-nil, the popup window will be
+ dedicated to the original popup buffer. In this case, when
+ another buffer is selected in the popup window, the popup
+ window will be closed immedicately and the selected buffer
+ will be shown on the previously selected window.
+
+ stick: If the value is non-nil, the popup window will be stuck
+ when it is shown.
+
+ tail: If the value is non-nil, the popup window will show the
+ last contents.
+
+Examples: With '(\"*scratch*\" :height 30 :position top),
+*scratch* buffer will be shown at the top of the frame with
