+This subdirectory contains a stack project for expected compilation failures. To
+add a new "test case", create a new `executable` stanza in the `package.yaml`
+file. The Travis CI test script ([`test.sh`](test.sh)) will attempt to compile
+the executable and will exit with an error if it successfully compiled.
