# Apache control script designed to allow an easy command line interface
# to controlling Apache.  Written by Marc Slemko, 1997/08/23
# 
# The exit codes returned are:
#   XXX this doc is no longer correct now that the interesting
#   XXX functions are handled by httpd
#	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
