Program returns an exit code of 1 when user requests help message.

This is very trivial, but I know it bothers some people. The showHelp function always exits with a return code of 1 even when the user requests the help message to be printed. This could be remedied by removing the "exit(1);" line from showHelp and placing it after calls to showHelp except in instances where showHelp is called because bShowHelp is true.
