Stalonetray is a STAnd-aLONE system TRAY (notification area) for X
Window System. It has full XEMBED support and minimal dependencies:
the X11 lib only. Stalonetray works with virtually any EWMH-compliant
window manager.

After install, copy stalonetrayrc.sample from the documentation folder
to ~/.stalonetrayrc, then you can start using it.
