# Preface

Throughout this Zend documentation, references are made to an example module in order to illustrate various concepts. The "counter" extension is this example, a fictional yet functional Zend module which strives to use as much of the Zend API as is reasonably possible. This short chapter describes the userland interface to the completed extension.

> Nota: "counter" serves no practical purpose whatsoever, as the functionality it provides is far more effectively implemented by appropriate userland code.
