+
+On line 4 you can see that the instantion of a type "__link" object needs
+the object "__file/etc/cdist-configured" to be present, before it can proceed.
+
+This also means that the "__link" command must make sure, that either
+"__file/etc/cdist-configured" allready is present, or, if it's not, it needs
+to be created. The task of cdist is to make sure, that the dependency will be
+resolved appropriately and thus "__file/etc/cdist-configured" be created
+if necessary before "__link" proceeds (or to abort execution with an error).
+
 All objects that are created in a type manifest are automatically required
 from the type that is calling them. This is called "autorequirement" in
 cdist jargon.
 
+You can find an more in depth description of the flow execution of manifests
+in cdist-stages(7) and of how types work in cdist-type(7).
