# Makefile for javascript in java.
#

# This makefile is intended for packaging releases, and probably isn't
# suitable for production use - it doesn't attempt to do understand
# java dependencies beyond the package level.
#
# The makefiles for the subdirectories included in this package are
# intended to be called by this makefile with the proper CLASSDIR,
# PATH_PREFIX etc. variables.  Makefiles in subdirectories are
# actually executed in the toplevel directory, with the PATH_PREFIX
# variable set to the subdirectory where the makefile is located.
#
# Initial version courtesy Mike Ang.
# Next version by Mike McCabe
