+// Package rtnetlink allows the kernel's routing tables to be read and altered.
+// Network routes, IP addresses, Link parameters, Neighbor setups, Queueing disciplines,
+// Traffic classes and Packet classifiers may all be controlled.
+// It is based on netlink messages.
+//
+// A convenient, high-level API wrapper is available using package rtnl:
+// https://godoc.org/github.com/jsimonetti/rtnetlink/rtnl.
+//
+// The base rtnetlink library xplicitly only exposes a limited low-level API to rtnetlink.
+// It is not the intention (nor wish) to create an iproute2 replacement.
+//
+// When in doubt about your message structure it can always be useful to look at the
+// message send by iproute2 using 'strace -f -esendmsg' or similar.
+//
+// Another (and possibly even more flexible) way would be using 'nlmon' and wireshark.
+// nlmod is a special kernel module which allows you to capture all (not just rtnetlink)
+// netlink traffic inside the kernel. Be aware that this might be overwhelming on a system
+// with a lot of netlink traffic.
+//
+//	# modprobe nlmon
+//	# ip link add type nlmon
+//	# ip link set nlmon0 up
+//
+// At this point use wireshark or tcpdump on the nlmon0 interface to view all netlink traffic.
+//
+// Have a look at the examples for common uses of rtnetlink.
