// CSL interface and main() function for use with CRAM: the CREATE Real-time Applications Manager
// See the copyright and acknowledgment of authors in the file COPYRIGHT
//
//  The CSLService class is the wrapper used to manage CSL programs from CRAM.
//  This file has the main() function that starts any of a number of different CSL services under the control of CRAM.
//
// Usage:
//  CSL_Server service_name listener_port emergency_port CSL_function [-o UDP_IO-port] [-i RemoteFrameStream-in-IP/port]
//      The name and l/e port arguments are used by the CRAM management system
//      The CSL function is a string to select from the built-in play routines (see the list below)
// Examples
//  CSL_Server CSL31 12345 12355 bells              -- play bells sending sound out to the local server
//  CSL_Server CSL31 12345 12355 speakers -o 33123  -- play voices listening for client requests on port 33123
//                                                  -- mix stereo sample streams from the two given servers
//  CSL_Server CSL31 12345 12355 mixer -i 128.111.92.51 12445 -i 128.111.92.60 12445
//
// The CSL_Function selects from the various available services:
//      bells       texture of random FM bells
//      noise       swept filtered noise
//      speakers    phoneme streams
//      mixer       8-in 2-out network mixer
//
// The optional arguments 
//      -o port-num -- for UDP_IO clients, to tell them their listener ports
//      -i client-IP client-port -- for processors, to identify their inputs
//      -a  -- for auto-start (run stand-alone without waiting for CRAM start message)
//
// The mixer takes additional arguments to describe its clients
