I have 2 files:  
index.php and Slim.php  
I post to you the index.php:

require “./Slim.php”;  
Slim::registerAutoloader();  
$app = new Slim();  
$app-\>get(’/{foo}’, function () {  
echo “Foo!”;  
});  
$app-\>run();

I don’t understand why it turns me that class Slim doesn’t exist can you help me?
