# This script generates auxiliary recipes for 'make test': e.g. in the case of JAVA,
# - a phony target 'java' depends on all of the testdir/input/java*.java
# - when the syntax file is changed, timestamps of the JAVA files are updated so that the tests will
#   be rerun against updated syntax
# - when a vim setup file for test, e.g. testdir/input/setup/java_module_info.vim, is changed,
#   timestamp of the corresponding input, testdir/input/java_module_info.java, is updated
#
# NOTE: At the moment this script DOES NOT strictly track dependency, like cpp on c, so run
# `make clean test` before deployment
