# 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_
# one is reported.  Run "apachectl help" for usage info
