-Obsolete
-========
-
-These modules are not normally available for import; additional work must be
-done to make them available.
-
-These extension modules written in C are not built by default. Under Unix, these
-must be enabled by uncommenting the appropriate lines in :file:`Modules/Setup`
-in the build tree and either rebuilding Python if the modules are statically
-linked, or building and installing the shared object if using dynamically-loaded
-extensions.
-
-.. XXX new explanation of lib-old necessary
-
-   Those which are written in Python will be installed into the directory
-   \file{lib-old/} installed as part of the standard library.  To use
-   these, the directory must be added to \code{sys.path}, possibly using
-   \envvar{PYTHONPATH}.

-:mod:`timing`
-   --- Measure time intervals to high resolution (use :func:`time.clock` instead).
