+37. User-registered management commands
+
+The manage.py utility provides a number of useful commands for managing a
+Django project. If you want to add a utility command of your own, you can.
+
+The user-defined command 'dance' is defined in the management/commands 
+subdirectory of this test application. It is a simple command that responds 
+with a printed message when invoked.
+
+For more details on how to define your own manage.py commands, look at the
+django.core.management.commands directory. This directory contains the
+definitions for the base Django manage.py commands.
