+subdir
+------
+
+The ``subdir`` stanza can be used to evaluate stanzas in subdirectories. This is
+useful for generated files or to override stanzas in vendored directories
+without editing vendored ``dune`` files.
+
+In this example, a ``bar`` target is created in the ``foo`` directory, and a bar
+target will be created in ``a/b/bar``:
+
+.. code:: dune
+
+   (subdir foo (rule (with-stdout-to bar (echo baz))))
+   (subdir a/b (rule (with-stdout-to bar (echo baz))))
