xclip 0.08-6 (amd64 binary) in ubuntu edgy

 xclip is a command line utility that is designed to run on any system with an
 X11 implementation. It provides an interface to X selections ("the clipboard")
 from the command line. It can read data from standard in or a file and place
 it in an X selection for pasting into other X applications. xclip can also
 print an X selection to standard out, which can then be redirected to a file
 or another program.
