Examples of arq.cmd.TerminationException

arq.cmd.TerminationException
Exception used to indicate that the command should end now. Use instead of System.exit so that a wrapper can catch (else a command server wil exit wrongly).

    
    public void cmdError(String msg, boolean exit)
    {
        System.err.println(msg) ;
        if ( exit )
            throw new TerminationException(5) ;
