Generating a link to a page, email, url, email in the TYPO3 Frontend is usually handled via the
so-called typolink functionality. Generating links is now flexible, extensions can register
their own link-building functionality via $GLOBALS[TYPO3_CONF_VARS][FE][typolinkBuilder][$linkType]
in the extensions ext_localconf.php.
All existing functionality for TypoLink via TypoScript etc. still works as before.
