+description: "Bisect_ppx helps you test thoroughly. It is a small preprocessor
+that inserts instrumentation at places in your code, such as if-then-else and
+match expressions. After you run tests, Bisect_ppx gives a nice HTML report
+showing which places were visited and which were missed.
+
+Usage is simple - add package bisect_ppx when building tests, run your tests,
+then run the Bisect_ppx report tool on the generated visitation files."
