+This is a Python script intended to be used with the "python_scripting.py" cmd2 example applicaiton.
+
+To run it you should do the following:
+    ./python_scripting.py
+    py run('script_conditional.py')
+    
+Note: The "cmd" function is defined within the cmd2 embedded Python environment and in there "self" is your cmd2
+application instance.
