+# tool/update-deps verify makefile dependencies.
+
+# Requirements:
+# gcc 4.5 (for -save-temps=obj option)
+# GNU make (for -p option)
+#
+# Warning: ccache (and similar tools) must be disabled for
+# -save-temps=obj to work properly.
+#
+# Usage:
+# 1. Compile ruby with -save-temps=obj option.
+# Ex. ./configure debugflags='-save-temps=obj -g' && make all golf
+# 2. Run tool/update-deps to show dependency problems.
+# Ex. ruby tool/update-deps
+# 3. Use --fix to fix makefiles.
+# Ex. ruby tool/update-deps --fix
+#
+# Other usages:
+# * Fix makefiles using previously detected dependency problems
+# Ex. ruby tool/update-deps --actual-fix [file]
+# "ruby tool/update-deps --fix" is same as "ruby tool/update-deps | ruby tool/update-deps --actual-fix".
