# It's not practical to build large Java programs from make, because of
# how Java does dependencies; so we use ant instead.  But we also cannot
# call ant from the main makefile (build.mk), since make will have no
# idea whether the target has changed or not.  So we call ant from here,
# and then the main makefile can treat the build products (jars) as inputs
