+    composer require --dev sebastian/comparator
+
+## Usage
+
+```php
+<?php
+use SebastianBergmann\Comparator\Factory;
+use SebastianBergmann\Comparator\ComparisonFailure;
+
+$date1 = new DateTime('2013-03-29 04:13:35', new DateTimeZone('America/New_York'));
+$date2 = new DateTime('2013-03-29 03:13:35', new DateTimeZone('America/Chicago'));
+
+$factory = new Factory;
+$comparator = $factory->getComparatorFor($date1, $date2);
+
+try {
+    $comparator->assertEquals($date1, $date2);
+    print "Dates match";
+} catch (ComparisonFailure $failure) {
+    print "Dates don't match";
+}
+```

+# sebastian/diff
+
+Diff implementation for PHP, factored out of PHPUnit into a stand-alone component.
+
+## Installation
+
+You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
+
+    composer require sebastian/diff
+
+If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
+
+    composer require --dev sebastian/diff
+
+### Usage
+
+The `Differ` class can be used to generate a textual representation of the difference between two strings:
+
+```php
+use SebastianBergmann\Diff\Differ;
+
+$differ = new Differ;
+print $differ->diff('foo', 'bar');
+```
+
+The code above yields the output below:
+
+    --- Original
+    +++ New
+    @@ @@
+    -foo
+    +bar
+
+The `Parser` class can be used to parse a unified diff into an object graph:
+
+```php
+use SebastianBergmann\Diff\Parser;
+use SebastianBergmann\Git;
+
+$git = new Git('/usr/local/src/money');
+
+$diff = $git->getDiff(
+  '948a1a07768d8edd10dcefa8315c1cbeffb31833',
+  'c07a373d2399f3e686234c4f7f088d635eb9641b'
+);
+
+$parser = new Parser;
+
+print_r($parser->parse($diff));
+```
+
+The code above yields the output below:
