# 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
#
