+    # Overwrite to implement a number of default options that all url_for-based methods will use. The default options should come in
+    # the form of a hash, just like the one you would use for url_for directly. Example:
+    #
+    #   def default_url_options(options)
+    #     { :project => @project.active? ? @project.url_name : "unknown" }
+    #   end
+    #
+    # As you can infer from the example, this is mostly useful for situations where you want to centralize dynamic decisions about the
+    # urls as they stem from the business domain. Please note that any individual url_for call can always override the defaults set
+    # by this method.
