-- | Haskell binding for Libnotify
--   
--   Usable binding to libnotify library.
@package libnotify

-- | System.Libnotify.Types module is a collection of types is used in
--   other modules. This is reexported with System.Libnotify module.
--   Perhaps it'll never be needed to import explicitly.

-- | Timeout in seconds after which notification is closed. Although
--   timeout does not work with notify-osd.
data Timeout

-- | Default server timeout.
Default :: Timeout

-- | User defined timeout (in milliseconds).
Custom :: Int -> Timeout

-- | Notification will not expire until user pays attention to it.
Infinite :: Timeout

-- | Urgency can be used by the notification server to prioritize
--   notifications. Although urgency does not work with notify-osd.
data Urgency

-- | Low priority notification.
Low :: Urgency

-- | Default notification urgency.
Normal :: Urgency

-- | Critical notification that requires immediate attention.
Critical :: Urgency

-- | Category can be used by the notification server to filter or display
--   the data in a certain way.

-- | Type synonim for notification title.

-- | System.Libnotify.Server module deals with notification server info
--   processing and initialized applications managing.

--   enough for a vast majority of applications.

-- | Initializes and uninitializes libnotify API. Any notifications API
--   calls should be wrapped into <tt>withNotifications</tt>, i.e.

-- | Creates new notification session. Inside <a>new</a> call one can
--   manage current notification via <a>update</a> or <a>render</a> calls.
--   Returns notification pointer. This could be useful if one wants to
--   <a>update</a> or <a>close</a> the same notification after some time
--   (see <a>continue</a>).
