# chkconfig - configuration state checker
#
# This script is written to work with the NetBSD (1.5 and later) rc system.
# It is meant to provide the same functionality as found in IRIX chkconfig.
# This script has nothing to do with the abortion produced by RedHat that
# has the same name.
#
# chkconfig makes use of the '-k' flag to rcorder. It will not work
# with versions of rcorder that do not support '-k'.
