|
|
;; This library implements a LaTeX exporter for org-mode.
|
|
;;
|
|
;; It is part of Org and will be autoloaded
|
|
;;
|
|
;; The interactive functions are similar to those of the HTML exporter:
|
|

|
|
;; M-x `org-export-as-latex'

;; M-x `org-export-as-pdf'
|
|
;; M-x `org-export-as-pdf-and-open'
|

;; M-x `org-export-as-latex-batch'

If BUFFER is a buffer or a string, use/create that buffer as a target
|
|
of the converted LaTeX. If BUFFER is the symbol `string', return the
|
|
produced LaTeX as a string and leave no buffer behind. For example,
|
|
a Lisp program could call this function in the following way:
|
|
|
|
(setq latex (org-export-region-as-latex beg end t 'string))
|
|
|
|
When called interactively, the output buffer is selected, and shown
|

in a window. A non-interactive call will only return the buffer."
