A minimal computer contract bridge communication protocol and implementation.
The protocol supports four players and a host program.
In EBNF, every message here ends with a newline. The number of brackets signifies the number of such messages being sent and the direction specifies whether the recipient is a player or the host.

Currently no support for:
- bidding
- different scoring/goals
- forming agreements
- disclosure
The host is an implementation of the jacobian protocol.
