//
// = DESCRIPTION
// This test attempts to communicate several Event Channels.
// The test hardcodes all the objects involved (consumers,
// suppliers, proxies, etc.); the objective is to gain understanding
// on the architecture needed to exploit locality in the Event
// cycle, not to provide a definite solution.

// A simple test for the EC_Proxy class.
//
// = DESCRIPTION
// This class is design to exercise several features of the EC_Proxy
// class and the multiple EC architecture.
// We want to create two EC, each one having a single supplier and a
// single consumer.
// + To test the remote facilities the consumer register for both a
// local event and a remote one.
// + To test the remote filtering features the remote consumer only
// wants one of the local events, and this event is generated less
// frequently.
//
// This class creates the local EC_Gateway a consumer and a
// supplier, it uses the command line to figure the subscriptions
// and publications list.
