# The darwin-daemon.eclass is designed to convert Gentoo init.d scripts
# into Mac OS X compatible format. It should be called from src_install()
# and will create necessary files in /Library/System/StartupItems.
#

# External function:
#	register-StartupItems
# Internal functions:
#	create-plist
#	convert-initd
#	parse-Items
#	map-Items
#	fakeuse
