+# Wrapper around morph for use by cmdtest tests. This does several things:
+#
+#   * simpler command lines for running morph, so that each test does not
+#     need to add --no-default-config and other options every time
+#   * replace temporary filenames ($DATADIR) in the output with a known
+#     string ("TMP"), so that test output is deterministic
