-# Tests for Differential against Timely master

-This directory contains tests for Differential against Timely master. The tests are run in the same way as the tests
-for Differential against released versions of Timely, but the crate is replaced with the `timely` crate from Github.
-
-Nobody should ever rely on the contents of this directory for any other purpose than testing differential
-against timely master.
