olaf is a simple multi-clipboard system.
It allows you to store the (textual) contents of the system clipboard in up to four virtual clipboards, so you can switch between several copied contents.
$ olaf &
$ # Hit Ctrl+c on any text.
$ # Save the copied content to a virtual clipboard by pressing Ctrl+u.
$ # Do your stuff without worrying about losing what you copied.
$ # Copy the contents back to the system clipboard by pressing Alt+u.
$ # Paste as usual with Ctrl+v.
v1.0.0 is the first stable release of the CLI program.
