     It now generates these dependencies:

-	    include/config/foo_model_two.h
+	    include/config/foo/autofrob.h \

     So drivers/net/foo.c depends only on the CONFIG_* lines that
     it actually uses.
 
-    A new program, split-include.c, runs at the end of make config (also
-    make oldconfig, make menuconfig, and make xconfig).  split-include
-    reads include/linux/autoconf.h and updates the include/linux/*.h
-    directory, writing one file per option.  It updates only the files
-    that changed.

-    mkdep.c also generates much better warning messages for missing
-    or unneeded <linux/config.h> lines.  In fact, you can get these
-    messages without generating dependencies with the new top-level
-    target 'make checkconfig'.
