+;; Overview
+;; ========
+;;
+;; This library provides two additional markers `!!' and `!@' over
+;; and above those in `org-emphasis-alist'.'
+;;
+;; - Text enclosed in `!!' is highlighted in yellow, and exported likewise
+;; - Text enclosed in `!@' is displayed in red, and exported likewise
+;;
+;; Following backends are supported: HTML and ODT. For export of extra

+;; [[https://github.com/kjambunathan/org-mode-ox-odt][Enhanced ODT]]
+;; exporter with version >= 9.5.3.467 (dtd. June 14, 2022 IST). This
+;; is the first version of the exporter that defines the user option
+;; `org-odt-extra-styles'.
+;;
+;; Example

+;; Add the following to your `user-init-file' and restart Emacs.

+;;
+
+;; Default Settings
+;; ================
+;;
+;; 16 Emphasis Markers
+;; ===================
+;;
+;; This library defines the following 16 emphasis markers,
+;;
+;; |----+----+----+----|
+;; | !! | !@ | !% | !& |
+;; |----+----+----+----|
+;; | @! | @@ | @% | @& |
+;; |----+----+----+----|
+;; | %! | %@ | %% | %& |
+;; |----+----+----+----|
+;; | &! | &@ | &% | && |
+;; |----+----+----+----|
+;;
+;; The above markers are all pairings of the following four characters:
+;; ! @ % &
+;;
+;; It is hoped that these set of emphasis markers don't pose issues
+;; while exporting.
+;;
+;; 17 Extra Emphasis Faces
+;; =======================
+;;
+;; This library defines 17 faces:
+;;
+;; - one base face `org-extra-emphasis'
+;; - 16 more faces `org-extra-emphasis-01',`org-extra-emphasis-02',
+;; ..., `org-extra-emphasis-16'.
+;;
+;; The later 16 faces derive from `org-extra-emphasis' face. Of
+;; these, only the first two faces `org-extra-emphasis-01' and
+;; `org-extra-emphasis-02' are explicitly configured. If you are
+;; using more than 2 emphasis markers, you may want to configure the
+;; other 14 faces.
+;;
+;; `org-extra-emphasis-alist' already associated 16 emphasis markers
+;; with 16 different faces.
+;;
+;; Customization
+;; =============
+;;
+;; Configuring your own Emphasis Markers
+;; =====================================
+;;
+;; 16 numbers of emphasis markers should suffice in practice.
+;; However, if none of the above emphasis markers resonate with you,
+;; you can customize `org-extra-emphasis-alist', and plug in your own
+;; markers. When choosing your own marker, ensure that you exercise
+;; some care. For example, if you choose `#' as a marker you are
+;; likely to get malformed `html' and `odt' files.
+;;
+;; Configuring Extra Emphasis Faces
+;; ===============================
+;;
+;; You can use `M-x customize-group RET org-extra-emphasis-faces RET'
+;; to configure the extra emphasis faces.
+;;
+;; Disabling the Extra Emphasis
+;; =============================
+;;
+;; You can use `M-x org-extra-emphasis-mode' to toggle this feature.
+;;
+;; Adding additional export backends
+;; =================================
+;;
+;; To add additional backends, modify `org-extra-emphasis-formatter'
+;; and `org-extra-emphasis-build-backend-regexp'.
