+
+   Runs MicroPython in "embedded mode":
+
+   * ``boot.py`` and ``main.py`` are executed; boot.py unconditionally,
+     ``main.py`` only if no script argument is used.
+
+   * Instead of the ``readline`` library, MicroPython uses the same REPL as

 .. option:: -m <module>
 
    Runs the module ``<module>``. The module must be in ``sys.path``.
