Lightweight GTK2-based systray for UNIX desktop

 trayer is a small program designed to provide systray functionality
 present in GNOME/KDE desktop environments for window managers which
 do not support that function. System tray is a place, where various
 applications put their icons, so they are always visible presenting
 status of applications and allowing user to control programs.

 The code started out as an extraction from fbpanel.
