+// ZeroTier Transport. This sits on the ZeroTier L2 network, which itself
+// is implemented on top of UDP. This requires the 3rd party
+// libzerotiercore library (which is GPLv3!) and platform specific UDP
+// functionality to be built in. Note that care must be taken to link
+// dynamically if one wishes to avoid making your entire application GPL3.
+// (Alternatively ZeroTier offers commercial licenses which may prevent
+// this particular problem.) This implementation does not make use of
+// certain advanced capabilities in ZeroTier such as more sophisticated
+// route management and TCP fallback. You need to have connectivity
+// to the Internet to use this. (Or at least to your Planetary root.)
+//
+// The ZeroTier URL format we support is zt://<ztid>.<nwid>:<port> where
+// the <nwid> component represents the 64-bit hexadecimal ZeroTier
+// network ID,the <ztid> represents the 40-bit hexadecimal ZeroTier
+// node (device) ID, and the <port> is a 24-bit (decimal) port number.
+//
+// A listener may replace the <ztid> with a wildcard, to just bind to itself,
+// in which case the format will be zt://*.<nwid>:<port>
+//
+// A listener may also use either 0 or * for the <port> to indicate that
+// a random local ephemeral port should be used.
+//
+// Because ZeroTier takes a while to establish connectivity, it is even
+// more important that applications using the ZeroTier transport not
+// assume that a connection will be immediately available. It can take
+// quite a few seconds for peer-to-peer connectivity to be established.
+//
+// The ZeroTier transport was funded by Capitar IT Group, BV.
