;;; Commentary:
;; Org-Babel support for evaluating LaTeX source code.
;;
;; Currently on evaluation this returns raw LaTeX code, however at
;; some point it *may* (it may not) make sense to have LaTeX blocks
;; compile small pdfs on evaluation.
;;; Code:
(require 'org-babel)
(org-babel-add-interpreter "latex")
(add-to-list 'org-babel-tangle-langs '("latex" "tex"))
(defvar org-babel-default-header-args:latex
'((:results . "latex") (:exports . "results"))
"Default arguments to use when evaluating a latex source block.")
(defun org-babel-execute:latex (body params)
"Execute a block of Latex code with org-babel. This function is
called by `org-babel-execute-src-block'."
