seems a little strange to me to have a return value and an out value, but OK

+        {
+            // Determin version by parsing top level README file.

sp: Determine

+            string[] lines = File.ReadAllLines(Path.Combine(root, "README"));
+            int version = -1;
+            revision = -1;
+            foreach (var line in lines)
+            {
+                if (line.StartsWith("Revision"))
+                    revision = Convert.ToInt32(line.Split(':')[1]);
+                if (line.StartsWith("Version"))
