rbw is an unofficial command line client for Bitwarden. Although
Bitwarden does come with its own command line client, it is limited
by being stateless - to use it, you're required to manually lock
and unlock the client, and pass the temporary keys around in
environment variables, which makes it very difficult to use. rbw
avoids this problem by maintaining a background process which is
able to hold the keys in memory, similar to the way that ssh-agent
or gpg-agent work. This allows the client to be used in a much
simpler way, with the background agent taking care of maintaining
the necessary state.
