functions in pyk.i -

             pyk, py_command  
         or value = pyk(py_command)  
 
    
    send PY_COMMAND to python front-end.  If the wish front-end is not  
    already running, pyk starts it.  
    In the second form, pyk suspends the yorick interpreted caller  
    until python invokes a pyk_resume command returing a value.  
    

             pyk_debug = 1  
         or pyk_debug = []  
 
    
    If pyk_debug is non-nil and non-zero, print message traffic to and  
    from wish.  This is useful for debugging py-yorick interaction.  
    

             pyk_import, filename  
 
    
    source FILENAME containing python program into python front-end.  
    If python front-end is not already running, pyk_source starts it.  
    

             pyk_resume value  
 
    
    This function must be invoked by the python front-end; it should  
    never be called by yorick programs.  
    
    When python receives a pyk_sync command, it must eventually  
    respond with a pyk_resume in order to unblock the pyk function.  
    

             pyk_set var1 val1 var2 val2 ...  
 
    
    This function is designed to be invoked by the python front-end;  
    it is not useful for yorick programs.  
    
    Equivalent to  
      var1=val1; var2=val2; ...  
    Handles at most 8 var/val pairs.  
    As a special case, if given an odd number of arguments, pyk_set  
    sets the final var to [], e.g.-  
      pyk_set var1 12.34 var2  
    is equivalent to  
      var1=12.34; var2=[];
