 ;;; Commentary:
 
 ;; This is the elisp interface to the CC Inbox system. The main
 ;; interface is the inbox.org file which manages personal tasks.
 
 ;; Users may use `org-capture' to insert tasks and notes into their
 ;; own `org-inbox-file' and refactor them to a more sensible
 ;; destination with `org-refile'.
