+#
+# Sample script creating 1 server node and 1 client node using a
+# range-based medium function - transmission is possible if nodes are
+# in range. Nodes are positioned in a 3D space (x,y,z),
+# at a distance of 10 (units) from each other (on the X axis).
+#
+# Differences in SyncUnit values in machines represent the differences
+# in their relative speed. This prevents the machines from
+# synchronizing in 100%, which is crucial for Contiki network stack
+# stability.
