;;; Commentary:
;;;; Principles
;;;;; Work on elements
;; We want to work on elements as returned by =org-element-parse-buffer=. We only convert to strings at the very end, when we send the list of those to =org-agenda-finalize-entries=.
;;;;; Preserve the call to =org-agenda-finalize-entries=
;; We want to preserve the final call to =org-agenda-finalize-entries= to preserve compatibility with other packages and functions.
;;; Code:
(require 'org)
(require 'org-agenda)
(require 'dash)
