Usage

From source file:je3.rmi.MudClient.java

/**
 * This main() method defines the standalone program that starts up a MUD
 * server.  If invoked with a single argument, it treats that argument as
 * the name of a file containing the serialized and compressed state of an
 * existing MUD, and recreates it.  Otherwise, it expects four command-line
 * arguments: the name of the MUD, the password, the name of the entrance
 * place for the MUD, and a description of that entrance place.
 * Besides creating the MudServer object, this program sets an appropriate
 * security manager, and uses the default rmiregistry to register the
 * the MudServer under its given name.//from www  . ja  va 2s  .  c  o  m
