+
+   libgccjit internally generates assembler, and uses "driver" code
+   for converting it to other formats (e.g. shared libraries).
+
+   By default, libgccjit will use an embedded copy of the driver
+   code.
+
+   This option can be used to instead invoke an external driver executable
+   as a subprocess; it is a thin wrapper around the C API
+   :c:func:`gcc_jit_context_set_bool_use_external_driver`.
+
+   This entrypoint was added in :ref:`LIBGCCJIT_ABI_5`; you can test for
+   its presence using
+
+   .. code-block:: c
+
+      #ifdef LIBGCCJIT_HAVE_gcc_jit_context_set_bool_use_external_driver
