pypbcms distinguishes between the server and the clients.
The server

• is the node all other nodes connect to
• controlls the other nodes
• launches the management shell
• does not need to be the same master/primary node other programs use as their master/primary node. It does not tell your program which master node it should use.
• is the node from which the plugins will be synced
• does not automatically launch a client on the same node.
• can broadcast its ip/port using UDP (option -b)
  The clients:
• are the nodes on which commands will be run
• do not offer a user interface
• can automatically connect to the server (option -a)
