/**
 * Facade to use, through its methods:
 * - the setInput() method to set the files and/or directories to parse
 * - the parse('name') method to start parsing, and building the model
 * - the helper method export('format', 'location') to export the model
 * 
 * For example:
 * <code>
 * $t = new PHP_UML();
 * $t->setInput('PHP_UML/');
 * $t->export('xmi', '/home/wwww/');
 * </code>
 * 
 * If you want to produce XMI without using the PHP parser, please refer to
 * the file /examples/test_with_api.php; it will show how you can build a
 * model by yourself, with the PHP_UML_Metamodel package.
