Where is orion-application.xml?

[Boz]

I've got Orion working fine on Mac OS X  but am having trouble getting 
the examples to work. The ejb examples deployed without complaint but 
the docs say to add....

        <user-manager class="com.evermind.ejb.EJBUserManager">
                <property name="home" value="com.evermind.ejb.EJBUser" />
                <property name="defaultGroups" value="users" />
        </user-manager>

... to META-INF/orion-application.xml but there is no such file anywhere 
in the orion tree. Any insight would be great.
