-   directories given as ``SRC`` (recursively in the case of
-   directories) into the destination directory ``DEST``, while

-   ``DEST`` should be a path under ``$SAGE_LOCAL``, generally. For

 The following is automatically added to each install script, so you
 should not need to add it yourself.
 
--  ``sdh_guard``: Wrapper for ``sdh_check_vars`` that checks some
-   common variables without which many/most packages won't build
-   correctly (``SAGE_ROOT``, ``SAGE_LOCAL``, ``SAGE_SHARE``). This is
-   important to prevent installation to unintended locations.

-   if found appends ``SONAME`` to the ``LD_PRELOAD`` environment variable.
