"invitebridge" is the brain of the whole system.  The system looks like this:

                             ----------
                             |player1@|
                             |machine1|
                             ----------
                                 | bridge@
                                 | machine1
                                 |
         ----------------------------------------
         |                       |              |
         |   ----------          |              |   bridge@  ----------
         |   |player4@|     invitebridge@       |   machine2 |player2@|
         |   |machine4|----    machine4  -------|------------|machine2|
         |   ----------          |              |            ---------
         ----------------------------------------
                                 | bridge@
                                 | machine3
                                 |               
                             ----------
                             |player3@|
                             |machine3|
                             ----------

To play the bridge game via compute communication, the central site needs
the "invitebridge" program and the remote sites need "bridge" program.
The game is started by issuing the following command:
   invitebridge player1@machine1 player2@machine2 player@machine3

In the given example, the player1 will be the North, the player2 will be
the East, and the player3 will be the South.  You, player4, are always 
the West.

The game record will be stored in "bridge.log" in your working directory.
The guide of bidding, playing,.. can be found in "bridge.README" which
is part of this package.
