This package allows you to get notifications when there is something to do (for org mode).

Sometimes, you need a reminder a few days before a deadline, e.g. to buy a present for a birthday, and then another notification one hour before to have enough time to choose the right clothes.

This package tries to satisfy the various needs.

In order to activate this package, you must add the following code into your .emacs or .emacs.d configuration:

(require org-notify)
(org-notify-start)
