# The exit codes returned are:
#	0 - operation completed successfully
#	1 - 
#	2 - usage error
#	3 - httpd could not be started
#	4 - httpd could not be stopped
#	5 - httpd could not be started during a restart
#	6 - httpd could not be restarted during a restart
#	7 - httpd could not be restarted during a graceful restart
#	8 - configuration syntax error

# When multiple arguments are given, only the error from the _last_
