 Mininet Examples

+These examples are intended to help you get started using
+Mininet's Python API:
 
-linearbandwidth.py
+linearbandwidth.py:
 
 This example shows how to create a custom topology programatically
 by subclassing Topo, and how to run a series of tests on it.
 
-scratchnet.py, scratchnetuser.py
+scratchnet.py, scratchnetuser.py:
 
 These two examples demonstrate how to create a network by using the lowest-
 level Mininet functions. Generally the higher-level API is easier to use,
 but scratchnet shows what is going on behind the scenes.
 
-udpbwtest.py
+udpbwtest.py:
 
 This example shows how to run a test across an entire network, and monitor
 the output of a set of hosts in real time.
