-;;; Commentary:
-
-;; Requirement:
-;; org-mode 6.33x or higher version
-;; The latest version of the org-mode is recommended.
-;; (see http://orgmode.org/)
-;;
-;; Usage:
-;; 1. Put this elisp into your load-path
-;; 2. Add (require 'org-tree-slide) in your .emacs
-;; 3. Open an org-mode file
-;; 4. Toggle org-tree-slide-mode (M-x org-tree-slide-mode)
-;; then Slideshow will start and you can find "TSlide" in mode line.
-;; 5. `C-<'/`C->' will move between slides
-;; 6. `C-x s c' will show CONTENT of the org buffer
-;; Select a heading and type `C-<', then Slideshow will start again.
-;; 7. Toggle org-tree-slide-mode again to exit this minor mode
-;;
-;; Recommended minimum settings:
-;; (global-set-key (kbd "<f8>") 'org-tree-slide-mode)
-;; (global-set-key (kbd "S-<f8>") 'org-tree-slide-skip-done-toggle)
-;;
-;; and three useful profiles are available.
-;;
-;; 1. Simple use
-;; M-x org-tree-slide-simple-profile
-;;
-;; 2. Presentation use
-;; M-x org-tree-slide-presentation-profile
-;;
-;; 3. TODO Pursuit with narrowing
-;; M-x org-tree-slide-narrowing-control-profile
-;;
-;; Type `C-h f org-tree-slide-mode', you can find more detail.
-;;
-;; Note:
-;; - Make sure key maps below when you introduce this elisp.
-;; - Customize variables, M-x customize-group ENT org-tree-slide ENT
-;; - see also moom.el (https://github.com/takaxp/moom) to control Emacs frame

-Requirement:
- org-mode 6.33x or higher version
- The latest version of the org-mode is recommended.
- (see http://orgmode.org/)
-
-Usage:
- 1. Put this elisp into your load-path
- 2. Add (require 'org-tree-slide) in your .emacs
- 3. Open an org-mode file
- 4. Toggle org-tree-slide-mode (M-x org-tree-slide-mode)
- then Slideshow will start and you can find "TSlide" in mode line.
- 5. <left>/<right> will move between slides
- 6. `C-x s c' will show CONTENT of the org buffer
- Select a heading and type <right>, then Slideshow will start again.
- 7. Toggle org-tree-slide-mode again to exit this minor mode
-
-Recommended minimum settings:
- (global-set-key (kbd "<f8>") 'org-tree-slide-mode)
- (global-set-key (kbd "S-<f8>") 'org-tree-slide-skip-done-toggle)
-
- and three useful profiles are available.
-
- 1. Simple use
- M-x org-tree-slide-simple-profile
-
- 2. Presentation use
- M-x org-tree-slide-presentation-profile
-
- 3. TODO Pursuit with narrowing
- M-x org-tree-slide-narrowing-control-profile
-
- Type `C-h f org-tree-slide-mode', you can find more detail.
-
-Note:
- - Make sure key maps below when you introduce this elisp.
- - Customize variables, M-x customize-group ENT org-tree-slide ENT
