Is there a clipboard cache manager out there?

Just about the most useful piece of software on my two windows boxen (cue smirks) is a little utility called CLCL, which caches the clipboard, providing access to previous entries. It's amazing how many tasks can be sped up by having several paste-able chunks stored. (CLCL caches 40 by default)
I was wondering if there is anything similar for Linux - my searches in YaST haven't turned up anything likely yet.
