When you first install a runtime, you will likely be prompted to add a directory
to your :envvar:`PATH`. This is optional, if you prefer to use the ``py``

To launch a specific runtime, the ``py`` command accepts a ``-V:<TAG>`` option.
This option must be specified before any others. The tag is part or all of the
identifier for the runtime; for those from the CPython team, it looks like the
can be used in a shebang, even if it is not on your :envvar:`PATH`. This allows
the use of shebangs like ``/usr/bin/python3.12`` to select a particular runtime.
+If no runtimes are installed, or if automatic installation is enabled, the
+requested runtime will be installed if necessary. See :ref:`pymanager-config`
+for information about configuration settings.
+
The ``/usr/bin/env`` form of shebang line will also search the :envvar:`PATH`
environment variable for unrecognized commands. This corresponds to the
behaviour of the Unix ``env`` program, which performs the same search, but
