A number of network related files were imported from the LiMon
project; these contain a somewhat unclear license statement:

	Copyright 1994 - 2000 Neil Russell.
	(See License)

I analyzed the source code of LiMon v1.4.2 which was used for this
import.  It does not contain any "License" file, but the top level
directory contains a file "COPYING", which turns out to be GPL v2
of June 1991.  So it is legitimate to conclude that the LiMon derived
files are also to be released under GPLv2.  Mark them as such.
