+DMD as a library
+================
+
+The tests in this module are high-level and mostly indented to make sure all
+necessary modules are included in the Dub package.
+
+The tests are executable single-file packages for the D's package manager `dub`
+and can be directly executed:
+
+```bash
+./lexer.d
+```
+
+If you want to see the log output or want to pass additional options, use `--single`:
+
+```bash
+dub --single -v lexer.d
+```
+
+If you don't have `dub` installed on your system,
+[install an official release](https://dlang.org/download.html).
