does it do, and what commands/programs/libraries does it provide?

It¹s used with OpenVPN to do transparent layer 2 bridging. Most people use
OpenVPN at layer 3 with routed networking.

With OpenVPN you can get bridged layer 2 between the OpenVPN endpoints just by using the tap device rather than tun. Only if you need to bridge to machines not in the OpenVPN star (server + multiple clients) should you need to get fancy about it.
