+
+    Note:
+        This script is not very fail proof.
+        something as little as a missing internet connection or a
+        slight amount of packet loss can cause the script to crash
+        or behave unexpectedly.
+
+        I'm open to suggestions and will be glad to help if you
+        have trouble getting the script to work.
