"""Toggle dunst notifications using dunstctl.

When notifications are paused using this module dunst doesn't get killed and
you'll keep getting notifications on the background that will be displayed when
unpausing. This is specially useful if you're using dunst's scripting
(https://wiki.archlinux.org/index.php/Dunst#Scripting), which requires dunst to
be running. Scripts will be executed when dunst gets unpaused.

Requires:
    * dunst v1.5.0+
