+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.")
