Trayer is a small program designed to provide system tray functionality that commonly found in GNOME/KDE desktop environments, for window managers which lack this feature. It is similar to other applications such as `peksystray' and `docker'. Trayer code was extracted from fbpanel, lightweight X11 desktop panel (port `x11/fbpanel' also available). You can find more about it on its homepage. WWW: https://github.com/sargon/trayer-srg
