+\deprecated{1.6}{Use the \refmodule{filecmp} module instead.}
+
+The \module{cmpcache} module provides an identical interface and similar
+functionality as the \refmodule{cmp} module, but can be a bit more efficient
+as it uses \function{statcache.stat()} instead of \function{os.stat()}
+(see the \refmodule{statcache} module for information on the
+difference).
+
+\note{Using the \refmodule{statcache} module to provide
+\function{stat()} information results in trashing the cache
+invalidation mechanism: results are not as reliable.  To ensure
+``current'' results, use \function{cmp.cmp()} instead of the version
+defined in this module, or use \function{statcache.forget()} to
+invalidate the appropriate entries.}
