Method Summary

void	displayUsage() Displays usage information for this program.
static void	main(java.lang.String[] args) Passes off all the work to the constructor so that we can pass in a reference to this class to the client.
void	processConfigFile(java.lang.String configFile) Processes the contents of the specified config file.
boolean	usingVerboseMode() Indicates whether the message writer is using verbose mode and therefore will display messages written with the writeVerbose method.
void	writeMessage(java.lang.String message) Writes the specified message to standard output.
void	writeVerbose(java.lang.String message) Writes the specified message to standard output if verbose mode is enabled.
