We can now use the command cabal new-run myott -- test --layer <somelayer> --pass <somepass> <path/to/j/file> <path/to/s/file> to test a particular pass of Myott against some test files.
cabal new-run myott -- test --layer <somelayer> --pass <somepass> <path/to/j/file> <path/to/s/file>
Adding actual test files seems like work for a future MR.
