*
* main - hello-world security demo main program.
*
* Calling Sequence:
* status = main(argc, argv);
*
* Inputs:
* argc = number of command line tokens
* argv -> list of addresses of command line tokens
* global helloText anchors the current message for display
* global helloPrintFreq = interval (in seconds)
*
* Outputs:
* returns error status on completion, 0 for normal termination
*
* Notes:
* In most environments, there is actually little benefit
* to doing an orderly shutdown, since the agent knows how
* to deal with the broken pipe that results if a sub-agent
* abruptly exits.
