+
+:mod:`platform` can also be invoked directly using the :option:`-m`
+switch of the interpreter::
+
+   python -m platform [--terse] [--nonaliased] [{nonaliased,terse} ...]
+
+The following options are accepted:
+
+.. program:: platform
+
+.. option:: --terse
+
+   Print terse information about the platform. This is equivalent to
+   calling :func:`platform.platform` with the *terse* argument set to ``True``.
+
+.. option:: --nonaliased
+
+   Print platform information without system/OS name aliasing. This is
+   equivalent to calling :func:`platform.platform` with the *aliased* argument
+   set to ``True``.
+
+You can also pass one or more positional arguments (``terse``, ``nonaliased``)
+to explicitly control the output format. These behave similarly to their
+corresponding options.
