ecd0562c5f
I started from the 78ec8e commit then cherry-picked and squashed commits that have been done in master since then, except the bad commits that overwrote the tree (in master) with the tree in maint. This commit also bumps the version number to 7.8.06. The only "fix" that was made between 78ec8e and the previous commit is e0072f which has been reported to break stuff.

;;; Commentary:
|
|
;;
|
|
|
|
;; 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.
