Parcellite is a lightweight GTK+ clipboard manager. This is a stripped 
down, basic-features-only clipboard manager with a small memory 
footprint for those who like simplicity.

Parcellite features a clipboard CLI. Unrecognized options and the 
contents of your standard input get copied to your clipboard. See the 
man page for some examples.
