| 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). |
| |
| \strong{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. |
