+# Generic makefile for building subdirectories.
+#
+# SUBDIRS variables to specify the subdirectories to build recursively.
+# Makefile has to include Subdirs.gmk AFTER all SUBDIRS variables are
+# defined.
+#
+# This file does not contain any rule.
+#
+# WARNING: This file is shared with other workspaces.
+#          So when it includes other files, it must use JDK_TOPDIR.
+
+#
+# SUBDIRS          subdirs for the base module always get built
+# SUBDIRS_<group>  subdirs for the named group
+#
+# By default, subdirs specified in the SUBDIRS and all SUBDIRS_* 
+# variables will be built.
+#
+# Variables of the currently supported groups are:
+#  SUBDIRS_desktop    
+#  SUBDIRS_management
+#  SUBDIRS_enterprise
+#  SUBDIRS_misc
+#  SUBDIRS_tools
+# 
+# Change to the above list also need to update 
+# make/common/shared/Sanity.gmk.  NOTE: this list is subject
+# to change.
+# 
+# Eventually we want to restructure the make directory
+# according to these grouping (e.g. make/desktop/...) and
+# the SUBDIRS_<group> variables would not be needed.
+# 
+
+# Iterate the subdirectories specified in $1.
+# - cd into each subdir and make them
+
+# Given a SUBDIRS* list (first argument), cd into them and make them
+#   SUBDIRS_MAKEFLAGS      Make settings for a subdir make
+#   SUBDIRS_MAKEFLAGS-$@   Make settings specific to this target
