What is "glipper"

__NOTOC__ Glipper is a clipboard utility for the GNOME Panel. It allows users of Unix-like operating systems to access a history of X Selections, any item of which can be reselected for pasting. Glipper is often described as the GNOME counterpart to KDE's Klipper. Older versions of Glipper could also be run outside of GNOME, but the newest version 1.0 is GNOME only because of its heavy integration into different GNOME techniques. However, it can be run inside Xfce4's panel using the XfApplet wrapper - and through it, into any custom session that uses xfce4-panel, such as Openbox sessions.
