		to support starting buildbot_worker through Gentoo's init system. To use this,
		execute \"emerge --config =${CATEGORY}/${PF}\" to create a new instance.
		Set up your build worker following the documentation, make sure the
		resulting directories are owned by the \"buildbot\" user and point
		\"${ROOT}etc/conf.d/buildbot_worker.myinstance\" at the right location.
		The scripts can	run as a different user if desired."
