+VarExporter Component
+=====================
+
+The VarExporter component allows exporting any serializable PHP data structure to
+plain PHP code. While doing so, it preserves all the semantics associated with
+the serialization mechanism of PHP (`__wakeup`, `__sleep`, `Serializable`,
+`__serialize`, `__unserialize`).
+
+It also provides an instantiator that allows creating and populating objects
+without calling their constructor nor any other methods.
+
+The reason to use this component *vs* `serialize()` or
+[igbinary](https://github.com/igbinary/igbinary) is performance: thanks to
+OPcache, the resulting code is significantly faster and more memory efficient
+than using `unserialize()` or `igbinary_unserialize()`.
+
+Unlike `var_export()`, this works on any serializable PHP value.
+
+It also provides a few improvements over `var_export()`/`serialize()`:
+
+ * the output is PSR-2 compatible;
+ * the output can be re-indented without messing up with `\r` or `\n` in the data
+ * missing classes throw a `ClassNotFoundException` instead of being unserialized to
+   `PHP_Incomplete_Class` objects;
+ * references involving `SplObjectStorage`, `ArrayObject` or `ArrayIterator`
+   instances are preserved;
+ * `Reflection*`, `IteratorIterator` and `RecursiveIteratorIterator` classes
+   throw an exception when being serialized (their unserialized version is broken
+   anyway, see https://bugs.php.net/76737).
