This Extension improves the cache clearing process of TYPO3.

It uses an enhanced tag handling to clear the cache in these use cases:

- When a content element is changed the cache of all pages is cleared
  where this content element is referenced by a shortcut.

- When a file or the metadata of a file is changed the cache of all
  pages is cleared where this file is used in the page properties
  or in content elements.

- When a file is changed the directory is detected and the cache of
  all pages is cleared where a folder collection references it.

- When a record of an Extension is changed the cache of all pages is
  cleared where a related plugin is used.
