 \subsubsection{Setting up servers}  
 {\tt ox\_launch} is a general purpose launcher.  This application  
 invokes a server and sets up the server-client communication  
 according to the protocol stated in Section \ref{launcher}, then  
 itself becomes a control server.  
 Several facilities related to {{\tt ox\_launch}} are provided  
 as built-in functions of Risa/Asir: a function to invoke a server  
 automatically from a give host name and a server name, and a set  
 of functions to execute the port generation, {\tt bind}, {\tt listen},  
 {\tt connect} and {\tt accept} operations on sockets individually.
