*  Author: Dan Rocco
*  Date Compiled: 01/11/02
*  A scripting event loop parser that accepts the
*  following protocol:
*  "exit"  : exit the program
*  "list"  : prints "list in protocol"
*  "chdir" : prints "chdir in the protocol"
*  "rename": prints "rename in protocol" 
*  anything will print an error message. */
