+# This Dockerfile specifies the recipe for creating an image for the tests
+# to run in.
+#
+# We install as many test dependencies here as we can, because these setup
+# steps can be cached.  They do *not* run every time we run the build.
+# The Docker image is only rebuilt when the Dockerfile (ie. this file)
+# changes.
