Ayatana Messaging Menu - shared library

 A place on the user's desktop that collects messages that need a response.
 .
 This menu provides a condensed and collected view of all of those messages
 for quick access, but without making them annoying in times that you want
 to ignore them.
 .
 This library contains information to build status providers to go into
 the messaging menu.
