# In order to use this makefile, make sure that
# java, javac, jtb, javacc and svn are in your $PATH!
# This should work for java 1.4 and java 5.0, 
# but make sure your JTB version matches your 
# Java version!
#
# Make targets:
# "all" (default): generates parser from grammar
#                  and compiles Java source code
# "clean"        : deletes all generated files
# "status"       : cleans and then gives subversion status
