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