-    Incredibly, this approach can cope with template name clashes between support
-    modules.
-
-    If there is a name clash this approach will work as long as ioc.db contains
-    a full path reference to the db template. The corresponding entry in the
-    req substitutions will also use a full path.
-
-    Unfortunately, this is not true for name clashes in req file include statements.
-    Autosave search path will be /epics/autosave only. I'm not expecting this to
-    ever come come up in practice. If it does, the solution is to rename the
-    template in one of the modules.
-
-    TODO: The overrides will not currently work if full paths are used for
-    templates. What is good for name clashes is bad for overrides. We should
-    probably encourage support.yaml to use search paths for DB templates
-    (unless there is a name clash) or have a re-think of this
+    Where the database template has a full path, this will be stripped in
+    substitution files created in step 5. At runtime autosave will be pointed at
+    the /epics/autosave folder for its search path. There is an issue with name
+    collisions that we will address if this ever arises.
