# SYNOPSIS
#
#   AX_NAGIOS_GET_INETD
#
# DESCRIPTION
#
#    This macro determines whether inetd or xinetd is being used
#    The argument are:
#        the init type as determined by AX_NAGIOS_GET_INIT
#    $inetd_type will be set and will be one of:
#        unknown (could not be determined)
#        launchd (Mac OS X)
#        smf10   (Solaris)
#        smf11   (Solaris)
#        upstart (Older Debian)
#        xinetd  (Most Linux, BSD)
#        inetd   (The rest)
