;; TODO: completion that makes sense!
;;; Commentary:
;; After (require 'planner-multi), you should be able to create tasks
;; on multiple pages using M-x planner-create-task-from-buffer or M-x
;; planner-create-task. Notes should also work if you have at least
;; remember--dev--1.0--patch-21.
;;; Contributors:
;; Jim Ottaway made this work better with planner-appt.el and fixed
;; several bugs.
;; Yann Hodique helped in porting this to use Muse rather than
;; emacs-wiki.
;; Sergey Vlasov provided a bugfix for lists with dates in them.
;; Marco Gidde provided a patch that fixes a problem with extraneous
;; brackets.
;; Seth Falcon contributed a small improvement to
;; `planner-multi-replan-task'.
