# Control files for the warnings and tests-warnings Ant targets
#
# "warnings-check" does the absolutely required checks;
# "warnings" adds some extra checks we're trying to drive out of existance.
# "warnings-tests-check" and "warnings-tests" are similar for the tests/ directory
#
# warnings-check:               java/ecj.warning.options-ci
# warnings adds                 java/ecj.warning.options
# tests-warnings-check adds:    java/ecj.warning.options-test-ci
# tests-warnings adds:          java/ecj.warning.options-test
