+To make your application transcript-testable, add text like this to your .py file
+(replacing CmdLineApp with your own application class's name).  Then, a cut-and-pasted
+version of a successful session with your application, saved as a text file, can serve
+as a test for future 
+
+Invoke the test later with `python myapplication.py --test mytranscripttestfile.ext`
+Wildcards can be used to test against multiple transcript files.
