+"""A simple example cmd2 application demonstrating the following:
+     1) Colorizing/stylizing output
+     2) Using multiline commands
+     3) Persistent history
+     4) How to run an initialization script at startup
+     5) How to group and categorize commands when displaying them in help
+     6) Opting-in to using the ipy command to run an IPython shell
+     7) Allowing access to your application in py and ipy
+     8) Displaying an intro banner upon starting your application
+     9) Using a custom prompt
+    10) How to make custom attributes settable at runtime
