# Custom test drivers: try the "recheck" functionality with test protocols
# that allow multiple testcases in a single test script.  This test not
# only checks implementation details in Automake's custom test drivers
# support, but also serves as a "usability test" for our APIs.
# See also related tests 'test-driver-custom-multitest-recheck2.test'
# and 'parallel-tests-recheck-override.test'.
# Keep in sync with 'tap-recheck.test'.
