+udpstat.d is a DTrace program to print UDP statistics every second,
+retrieved from the MIB provider.
+
+The UDP statistics are documented in the mib2_tcp struct
+in /usr/include/inet/mib2.h; and also in the mib provider
+chapter of the DTrace Guide, found at
+http://docs.sun.com/db/doc/817-6223.
+
+Since this uses DTrace, only the root user or users with the
+dtrace_kernel privilege can run this command.
