;;;_ + Commentary:
;; You can use `planner-tasks-overview' to see a list of tasks between
;; two dates. `planner-tasks-overview-jump' jumps to the linked task.
;; To change the sort order, invoke the following functions:
;; `planner-tasks-overview-sort-by-date'
;; `planner-tasks-overview-sort-by-plan'
;; `planner-tasks-overview-sort-by-category'
;; `planner-tasks-overview-sort-by-status'
;;
;; This file was inspired by Markus Hoenicka's
;; http://www.mhoenicka.de/software/hacks/tasklist.html and Frederick
;; Fouvry's Lisp port of tasklist.pl.
;;;_ + Contributors
;; Andrew J. Korty (ajk AT iu DOT edu) provided a patch that corrected
;; a typo in the keymap.
;; Yann Hodique helped port this to Muse.
