+ * ClassLoader implements a PSR-0, PSR-4 and classmap class loader.
+ *
+ *     $loader = new \Composer\Autoload\ClassLoader();
+ *
+ *     // register classes with namespaces
+ *     $loader->add('Symfony\Component', __DIR__.'/component');
+ *     $loader->add('Symfony',           __DIR__.'/framework');
+ *
+ *     // activate the autoloader
+ *     $loader->register();
+ *
+ *     // to enable searching the include path (eg. for PEAR packages)
+ *     $loader->setUseIncludePath(true);
+ *
+ * In this example, if you try to use a class in the Symfony\Component
+ * namespace or one of its children (Symfony\Component\Console for instance),
+ * the autoloader will first look for the class under the component/
+ * directory, and it will then fallback to the framework/ directory if not
+ * found before giving up.
+ *
+ * This class is loosely based on the Symfony UniversalClassLoader.

+/**
+ * Class for SQL SELECT fragments.
+ *
+ * This class simply holds a string, so that fragments of SQL statements can be
+ * distinguished from identifiers and values that should be implicitly quoted
+ * when interpolated into SQL statements.
+ *
+ * For example, when specifying a primary key value when inserting into a new
+ * row, some RDBMS brands may require you to use an expression to generate the
+ * new value of a sequence.  If this expression is treated as an identifier,
+ * it will be quoted and the expression will not be evaluated.  Another example
+ * is that you can use Expr in the Select::order() method to
+ * order by an expression instead of simply a column name.
+ *
+ * The way this works is that in each context in which a column name can be
+ * specified to methods of Zend_Db classes, if the value is an instance of
+ * Expr instead of a plain string, then the expression is not quoted.
+ * If it is a plain string, it is assumed to be a plain column name.
