The Auth class has a __call__ method, which means Auth objects are 
callable. There's nothing special about the name "auth" -- it's just a 
convention. You could just as well do:

myauth = Auth(db)
myauth()

When you call auth(), it checks request.args(0) to see which Auth action 
has been requested and then calls the appropriate method (which in many 
cases produces a form).
