+handles the lookup of applicable dir-locals files (@file{.dir-locals.el}):
+instead of starting at the directory of the visited file and moving up the
+directory tree only until a first dir-locals file is found, collect and apply
+all (!) dir-locals files found from the current directory up to the root one.
+
+Values specified in files nearer to the current directory take precedence over
+values in files farther away from it.
+
+You might want to use this to globally set dir-local variables that apply to
+all of your projects, then override or add variables on a per-project basis.")
