pcopy is a tool to copy/paste across machines. It can be used from the web UI, via a CLI or without a client by using curl. It can also be used as a self-hosted NoPaste or as a temporary file hosting service.
CL3 started as a lightweight clone of the CLCL clipboard caching utility which can be found at http://www.nakka.com/soft/clcl/index_eng.html. But some unique features have been added making it more versatile "text only" Clipboard manager.
