+Create a link to ``<file>`` at ``<new-file>``.
+
+It is a hard link by default. This can be changed to symbolic links by
+using ``SYMBOLIC``. The original file needs to exist for hard links.
+
+The ``<result>`` variable, if specified, gets the status of the operation.
+It is set to ``0`` in case of success. Otherwise, it contains the error
+generated. In case of failures, if ``RESULT`` is not specified, a fatal error
+is emitted.
+
+Specifying ``COPY_ON_ERROR`` enables copying the file as a fallback if
+creating the link fails.
+
+Overwrites the ``<new-file>`` if it exists.
