+========================
+ Many Tests lit Example
+========================
+
+This directory contains a trivial lit test suite configuration that defines a
+custom test format which just generates a large (N=10000) number of tests that
+do a small amount of work in the Python test execution code.
+
+This test suite is useful for testing the performance of lit on large numbers of
+tests.
