+Exporter
+========
+
+[![Build Status](https://secure.travis-ci.org/sebastianbergmann/exporter.png?branch=master)](https://travis-ci.org/sebastianbergmann/exporter)
+
+This component provides the functionality to export PHP variables for visualization.
+
+## Usage
+
+Exporting:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Exception Object &0000000078de0f0d000000002003a261 (
+    'message' => ''
+    'string' => ''
+    'code' => 0
+    'file' => '/home/sebastianbergmann/test.php'
+    'line' => 34
+    'trace' => Array &0 ()
+    'previous' => null
+)
+*/
+
+print $exporter->export(new Exception);
+```
+
+## Data Types
+
+Exporting simple types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// 46
+print $exporter->export(46);
+
+// 4.0
+print $exporter->export(4.0);
+
+// 'hello, world!'
+print $exporter->export('hello, world!');
+
+// false
+print $exporter->export(false);
+
+// NAN
+print $exporter->export(acos(8));
+
+// -INF
+print $exporter->export(log(0));
+
+// null
+print $exporter->export(null);
+
+// resource(13) of type (stream)
+print $exporter->export(fopen('php://stderr', 'w'));
+
+// Binary String: 0x000102030405
+print $exporter->export(chr(0) . chr(1) . chr(2) . chr(3) . chr(4) . chr(5));
+```
+
+Exporting complex types:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+/*
+Array &0 (
+    0 => Array &1 (
+        0 => 1
+        1 => 2
+        2 => 3
+    )
+    1 => Array &2 (
+        0 => ''
+        1 => 0
+        2 => false
+    )
+)
+*/
+
+print $exporter->export(array(array(1,2,3), array("",0,FALSE)));
+
+/*
+Array &0 (
+    'self' => Array &1 (
+        'self' => Array &1
+    )
+)
+*/
+
+$array = array();
+$array['self'] = &$array;
+print $exporter->export($array);
+
+/*
+stdClass Object &0000000003a66dcc0000000025e723e2 (
+    'self' => stdClass Object &0000000003a66dcc0000000025e723e2
+)
+*/
+
+$obj = new stdClass();
+$obj->self = $obj;
+print $exporter->export($obj);
+```
+
+Compact exports:
+
+```php
+<?php
+use SebastianBergmann\Exporter\Exporter;
+
+$exporter = new Exporter;
+
+// Array ()
+print $exporter->shortenedExport(array());
+
+// Array (...)
+print $exporter->shortenedExport(array(1,2,3,4,5));
+
+// stdClass Object ()
+print $exporter->shortenedExport(new stdClass);
+
+// Exception Object (...)
+print $exporter->shortenedExport(new Exception);
+
+// this\nis\na\nsuper\nlong\nstring\nt...\nspace
+print $exporter->shortenedExport(
+<<<LONG_STRING
+this
+is
+a
+super
+long
+string
+that
+wraps
+a
+lot
+and
+eats
+up
+a
+lot
+of
+space
+LONG_STRING
+);
+```
+
+## Installation
+
+To add Exporter as a local, per-project dependency to your project, simply add a dependency on `sebastian/exporter` to your project's `composer.json` file. Here is a minimal example of a `composer.json` file that just defines a dependency on Exporter 1.0:
+
+    {
+        "require": {
+            "sebastian/exporter": "1.0.*"
+        }
+    }
