;; This package generalizes the #+begin_foo and #+end_foo tokens.
|
|
|
|
|
|
|
|
;; To use, put the following in your init file:
|
|
|
|
;;
|
|
|
|
;; (require 'org-special-blocks)
|
|
|
|
|
|
|
|
;; The tokens #+begin_center, #+begin_verse, etc. existed previously.
|
|
|
|
;; This package generalizes them (at least for the LaTeX and html
|
|
|
|
;; exporters). When a #+begin_foo token is encountered by the LaTeX
|
|
|
|
;; exporter, it is expanded into \begin{foo}. The text inside the
|
|
|
|
;; environment is not protected, as text inside environments generally
|
|
|
|
;; is. When #+begin_foo is encountered by the html exporter, a div
|
|
|
|
;; with class foo is inserted into the HTML file. It is up to the
|
|
|
|
;; user to add this class to his or her stylesheet if this div is to
|
|
|
|
;; mean anything.
