;;; Commentary:

;; Provides a way to evaluate sed scripts in Org mode.

;;; Usage:

;; Add to your Emacs config:

;; (org-babel-do-load-languages
;;  'org-babel-load-languages
;;  '((sed . t)))

;; In addition to the normal header arguments, ob-sed also provides
;; :cmd-line and :in-file. :cmd-line allows one to pass other flags to
;; the sed command like the "--in-place" flag which makes sed edit the
;; file pass to it instead of outputting to standard out or to a
;; different file. :in-file is a header arguments that allows one to
;; tell Org Babel which file the sed script to act on.

;;; Code:
(require 'ob)
