+# tool/update-deps assists you to update dependencies in common.mk.
+
+# This script uses preprocessed source files (*.i) to extract
+# dependencies.
+# It is possible to generate *.i using gcc with -save-temps option as:
+#
+# ./configure CFLAGS='-save-temps'
+# make all golf
+#
+# After that, tool/update-deps generate common.mk with up-to-date dependencies.
+# Currently, the result is not perfect around version.o, compile.o, etc.
+# So you must see each changes and incorporate right changes.
