+DESCRIPTION
+===========
+
+Configures networking.
+
+USAGE
+=====
+
+Set the networking attributes in a role, for example from my base.rb:
+
+    :networking => {
+      :nameservers => [ "10.13.37.120", "10.13.37.40" ],
+      :search => [ "int.example.org". "example.org" ]
+    }
+
+The resulting /etc/resolv.conf will look like:
+
+    search int.example.org example.org
+    nameserver 10.13.37.120
+    nameserver 10.13.37.40
