Also remove blank lines before the ";;; org*el ends here" declarations. Having a "Version" header forced us to update every file when releasing a new version of Org; it also forced us to update every file when merging Org with Emacs trunk, thus cluttering the diffs between the previously merged version and the new one with useless information. Glenn Morris suggested this in emacs-devel: http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00322.html

;; Org-Babel support for evaluating maxima entries.
|
|
;;
|
|
;; This differs from most standard languages in that
|
|
;;
|
|
;; 1) there is no such thing as a "session" in maxima
|
|
;;
|
|
;; 2) we are generally only going to return output from maxima
|
|
;;
|
|
;; 3) we are adding the "cmdline" header argument
|
|
;;
|
|
;; 4) there are no variables
|
|
|
|

(require 'ob)
