# There is one %.v.log target per %.v test file. The target will be
# filled with the output, timings and status of the test. There is
# also one target per directory containing %.v files, that runs all
# the tests in it. As convenience, there is also the "bugs" target
# that runs all bug-related tests.

# The "summary" target outputs a summary of all tests that were run
# (but doesn't run them)

# The "run" target runs all tests that have not been run yet. To force
# all tests to be run, use the "clean" target.
