See attached an ebuild for Parcellite, a lightweight GTK+ clipboard manager. Parcellite is rather similar to Glipper (x11-misc/glipper), although newer and with more features. It is hosted by Google Code at http://code.google.com/p/xyhthyx/ and is released under the GPL Version 3. Unlike Glipper, it is not specifically targeted at GNOME; any GTK+-enabled platform should work. Documentation is presently lacking, although usage is rather straight-forward. I propose the category x11-misc as this is where Glipper also resides. Parcellite 0.6 depends on GTK+ 2.10 or greater.
