- Extract a list of TCP/IP name servers from the registry 0.1
-    0.1 Strobl 2001-07-19
- Usage:
-    RegistryResolve() returns a list of ip numbers (dotted quads), by
-    scouring the registry for addresses of name servers
-
- Tested on Windows NT4 Server SP6a, Windows 2000 Pro SP2 and
- Whistler Pro (XP) Build 2462 and Windows ME
- ... all having a different registry layout wrt name servers :-/
-
- Todo:
-
-   Program doesn't check whether an interface is up or down

-# Fix win32 nameserver discovery.

-# Revision 1.3  2002/05/06 06:15:31  anthonybaxter
-# apparently some versions of windows return servers as unicode
-# string with space sep, rather than strings with comma sep.
-# *sigh*

-# Revision 1.2  2002/03/19 12:41:33  anthonybaxter
-# tabnannied and reindented everything. 4 space indent, no tabs. yay.
-#
-# Revision 1.1  2001/08/09 09:22:28  anthonybaxter
-# added what I hope is win32 resolver lookup support. I'll need to try
-# and figure out how to get the CVS checkout onto my windows machine to
-# make sure it works (wow, doing something other than games on the
-# windows machine :)

-# Code from Wolfgang.Strobl@gmd.de

-# Really, ParseResolvConf() should be renamed "FindNameServers" or some such.
