*  Description:
*     SPI (Server Protocol Interpreter) defines
*
*    Declarations for the Server Protocol Interpreter (called the
*    server-PI in the RFC).  The server protocol interpreter listens
*    for a control connection from a client protocol interpreter and
*    establishes a control communication connection.  It receives
*    standard FTP commands from the client protocol interpreter, sends
*    replies, and governs the server data transfer process.
