# proc.inetd_remove -- common code for inetd.conf entry removal
#
# inetd_init	: call before any other functions
# inetd_remove	: remove daemons specified as arguments by removing
#		  lines from inetd.conf that match the regular
#		  expressions provided on stdin (one per line)
# inetd_undo	: call if rest of procedure script fails
# inetd_fini	: call if rest of procedure script succeeds
#
# inetd_init and inetd_remove will perform necessary clean-up and
# return a non-zero exit code on failure.
