wayclip is a pair of command-line utilities: waycopy and waypaste, which allow access to the Wayland clipboard. Specifically, wayclip is a wlr-data-control protocol client.
wayclip distinguishes itself from other Wayland clipboard utilities in the following ways:
small - the whole codebase is less than 300 lines! (excluding whitespace)
Unixy - all it does is copy and paste; other functions are for other programs
