Comments:       This is the Central Regulatory Domain Agent for Linux. It serves one
		purpose: tell Linux kernel what to enforce. In essence it is a udev
		helper for communication between the kernel and userspace. You only
		need to run this manually for debugging purposes. For manual changing
		of regulatory domains use iw (iw reg set) or wpa_supplicant (feature
		yet to be added).
