A command line drag-and-drop tool for GNOME

 Dragbox is a tool for connecting the command line with
 the desktop environment. It summons a drag handle in a
 window when you are managing files or text in the shell,
 connecting the different workspaces -- desktop and
 command line.
 .
 Dragbox can take items on the command line or from a
 pipe and put on its shelf. The inverse is also possible:
 dragged-to items can be output to the shell.
