+# There are three ways this Makefile can be called:
+#
+# 
+# 1.  As a subdirectory from the toplevel, for automake
+#
+# 2. A wrapper around the kernel's makefile when building modules, to
+#    possibly override the .config file
+#
+# 3.  At configure time, as the toplevel module dir for building
+#     kernel tests
