* See http://www.php.net/manual/en/function.sprintf.php
*
* Examples
* ========
*
* Scientific notation
* -------------------
*
* ::

* <f:format.printf arguments="{number: 362525200}">%.3e</f:format.printf>
*
* Output::
*
* 3.625e+8
*
* Argument swapping
* -----------------
*
* ::
*
* <f:format.printf arguments="{0: 3, 1: 'Kasper'}">%2$s is great, TYPO%1$d too. Yes, TYPO%1$d is great and so is %2$s!</f:format.printf>
*
* Output::
*
* Kasper is great, TYPO3 too. Yes, TYPO3 is great and so is Kasper!
*
* Single argument
* ---------------
*
* ::
*
* <f:format.printf arguments="{1: 'TYPO3'}">We love %s</f:format.printf>
*
*
* Output::
*
* We love TYPO3
*
* Inline notation
