# 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.

# 

# BUILD_MODULES variable can be used to specify one or more groups

# to be built (BUILD_MODULES=all will build all groups).

#

# 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 till the JDK 7 SE profiles/modules are finalized.

# 

# 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.

# 

# To build the desktop and tools groups only, you can do:

# gnumake BUILD_MODULES="desktop tools" ...

# 

# 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

#
