Asterisk in Java Play MVC Framework's Routes File

Asterisk in Java Play MVC Framework's Routes File

I've inherited a project in the Play Framework. I'm in the process of
modifying the conf/routes file and was wondering why asterisks were used
instead of the normal HTTP methods as described in the documentation here:
http://www.playframework.com/documentation/2.0/JavaRouting
Here's and example of what I mean:
# Top level pages
GET /how-tradjenta-works Application.about
GET /prescription-savings-card SavingsCard.index
* /prescription-savings-card/qualify SavingsCard.qualify
As you can see, the third route definition has that asterisk. What gives?
