<h1 class="title">Preface</h1>
<p class="simpara">
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.

<blockquote class="note"><p><strong class="note">Note</strong>:
<span class="simpara">
"counter" serves no practical purpose whatsoever, as the functionality it
provides is far more effectively implemented by appropriate userland code.
