Symfony2 ClassLoader Component

The ClassLoader Component loads your project classes automatically if they
follow some standard PHP conventions.

Whenever you use an undefined class, PHP uses the auto-loading mechanism to
delegate the loading of a file defining the class. Symfony2 provides a
"universal" auto-loader, which is able to load classes from files that
implement one of the following conventions:

* The technical interoperability standards (http://symfony.com/PSR0) for
  PHP 5.3 name-spaces and class names.

* The PEAR (http://pear.php.net/manual/en/standards.php) naming convention for
  classes.

If your classes and the third-party libraries you use for your project follow
these standards, the Symfony2 auto-loader is the only auto-loader you will
ever need.
