#-*-makefile-*-
######################################################################
#
# Contains the shared make rules for the tools/java tree.
#
# In each directory, create a Makefile that includes the lines
# ROOT = <path to this directory>
# include $(ROOT)/Makefile.include
#
# By default the Makefile will compile all .java source code in the
# current directory. You may also specify the following flags in
# your Makefile, *before* including Makefile.include:
#
# SUBDIRS = dir1 dir2 ...
# Specify a list of subdirectories that 'make' should descend into
#
# INITIAL_TARGETS = target1 target2 ...
# Specify build targets to be compiled before compiling Java classes
#
# FINAL_TARGETS = target1 target2 ...
# Specify build targets to be compiled after compiling Java classes
#
# OTHER_CLEAN = target1 target2 ...
# Specify other targets to be executed when 'make clean' is run
#
# NOTE: this Makefile requires GNU make, as well as a number of
# standard UNIX shell tools.
