--- Manage a notification action list.
--
-- A notification action is a "button" that will trigger an action on the sender
-- process. `notify-send` doesn't support actions, but `libnotify` based
-- applications do.
--
--@DOC_wibox_nwidget_actionlist_simple_EXAMPLE@
--
-- This example has a custom vertical widget template:
--
--@DOC_wibox_nwidget_actionlist_fancy_EXAMPLE@
--
-- This example has a horizontal widget template and icons:
--
--@DOC_wibox_nwidget_actionlist_fancy_icons_EXAMPLE@
--
-- This example uses the theme/style variables instead of the template. This is
-- less flexible, but easier to put in the theme file. Note that each style
-- variable has a `beautiful` equivalent.
