<?php

For compatibility and reusability of your code, PSR1 recommends that a file should introduce either new symbols (like classes, functions, etc.) or have side-effects (like outputting something, or including other files), but not both at the same time. The first symbol is defined on line 12 and the first side effect is on line 5.

/**

App::uses('String', 'Utility');

/**
 * Dot Shell Class
 *
 * Simple dot generation of PNG files from state-machine
 */
class DotShell extends Shell {

PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.
