+
+Assetic is an asset management framework for PHP.
+
+``` php
+<?php
+
+use Assetic\Asset\AssetCollection;
+use Assetic\Asset\FileAsset;
+use Assetic\Asset\GlobAsset;
+
+$js = new AssetCollection(array(
+    new GlobAsset('/path/to/js/*'),
+    new FileAsset('/path/to/another.js'),
+));
+
+// the code is merged when the asset is dumped
+echo $js->dump();
+```
+
+Assets
+------
+
+An Assetic asset is something with filterable content that can be loaded and
+dumped. An asset also includes metadata, some of which can be manipulated and
+some of which is immutable.
+
+| **Property** | **Accessor**    | **Mutator**   |
+|--------------|-----------------|---------------|
+| content      | getContent      | setContent    |
+| mtime        | getLastModified | n/a           |
+| source root  | getSourceRoot   | n/a           |
+| source path  | getSourcePath   | n/a           |
+| target path  | getTargetPath   | setTargetPath |
+
+Filters
+-------
+
+Filters can be applied to manipulate assets.
+
+``` php
+<?php
+
+use Assetic\Asset\AssetCollection;
+use Assetic\Asset\FileAsset;
+use Assetic\Asset\GlobAsset;
+use Assetic\Filter\LessFilter;
+use Assetic\Filter\Yui;
+
+$css = new AssetCollection(array(
+    new FileAsset('/path/to/src/styles.less', array(new LessFilter())),
+    new GlobAsset('/path/to/css/*'),
+), array(
+    new Yui\CssCompressorFilter('/path/to/yuicompressor.jar'),
+));
+
+// this will echo CSS compiled by LESS and compressed by YUI
+echo $css->dump();
+```
+
+The filters applied to the collection will cascade to each asset leaf if you
+iterate over it.
+
+``` php
+<?php
+
+foreach ($css as $leaf) {
+    // each leaf is compressed by YUI
+    echo $leaf->dump();
+}
+```
+
+The core provides the following filters in the `Assetic\Filter` namespace:
+
+ * `CoffeeScriptFilter`: compiles CoffeeScript into Javascript
+ * `CssEmbedFilter`: embeds image data in your stylesheets
+ * `CssImportFilter`: inlines imported stylesheets
+ * `CssMinFilter`: minifies CSS
+ * `CssRewriteFilter`: fixes relative URLs in CSS assets when moving to a new URL
+ * `GoogleClosure\CompilerApiFilter`: compiles Javascript using the Google Closure Compiler API
+ * `GoogleClosure\CompilerJarFilter`: compiles Javascript using the Google Closure Compiler JAR
+ * `JpegoptimFilter`: optimize your JPEGs
+ * `JpegtranFilter`: optimize your JPEGs
+ * `LessFilter`: parses LESS into CSS (using less.js with node.js)
+ * `LessphpFilter`: parses LESS into CSS (using lessphp)
+ * `OptiPngFilter`: optimize your PNGs
+ * `PackerFilter`: compresses Javascript using Dean Edwards's Packer
+ * `PngoutFilter`: optimize your PNGs
+ * `CompassFilter`: Compass CSS authoring framework
+ * `Sass\SassFilter`: parses SASS into CSS
+ * `Sass\ScssFilter`: parses SCSS into CSS
+ * `SprocketsFilter`: Sprockets Javascript dependency management
+ * `StylusFilter`: parses STYL into CSS
+ * `Yui\CssCompressorFilter`: compresses CSS using the YUI compressor
+ * `Yui\JsCompressorFilter`: compresses Javascript using the YUI compressor
+
+Asset Manager
+-------------
+
+An asset manager is provided for organizing assets.
+
+``` php
+<?php
+
+use Assetic\AssetManager;
+use Assetic\Asset\FileAsset;
+use Assetic\Asset\GlobAsset;
+
+$am = new AssetManager();
+$am->set('jquery', new FileAsset('/path/to/jquery.js'));
+$am->set('base_css', new GlobAsset('/path/to/css/*'));
+```
+
+The asset manager can also be used to reference assets to avoid duplication.
+
+``` php
+<?php
+
+use Assetic\Asset\AssetCollection;
+use Assetic\Asset\AssetReference;
+use Assetic\Asset\FileAsset;
+
+$am->set('my_plugin', new AssetCollection(array(
+    new AssetReference($am, 'jquery'),
+    new FileAsset('/path/to/jquery.plugin.js'),
+)));
+```
+
+Filter Manager
+--------------
+
+A filter manager is also provided for organizing filters.
+
+``` php
+<?php
+
+use Assetic\FilterManager;
+use Assetic\Filter\Sass\SassFilter;
+use Assetic\Filter\Yui;
+
+$fm = new FilterManager();
+$fm->set('sass', new SassFilter('/path/to/parser/sass'));
+$fm->set('yui_css', new Yui\CssCompressorFilter('/path/to/yuicompressor.jar'));
+```
+
+Asset Factory
+-------------
+
+If you'd rather not create all these objects by hand, you can use the asset
+factory, which will do most of the work for you.
+
+``` php
+<?php
+
+use Assetic\Factory\AssetFactory;
+
+$factory = new AssetFactory('/path/to/asset/directory/');
+$factory->setAssetManager($am);
+$factory->setFilterManager($fm);
+$factory->setDebug(true);
+
+$css = $factory->createAsset(array(
+    '@reset',         // load the asset manager's "reset" asset
+    'css/src/*.scss', // load every scss files from "/path/to/asset/directory/css/src/"
+), array(
+    'scss',           // filter through the filter manager's "scss" filter
+    '?yui_css',       // don't use this filter in debug mode
+));
+
+echo $css->dump();
+```
+
+Prefixing a filter name with a question mark, as `yui_css` is here, will cause
+that filter to be omitted when the factory is in debug mode.
+
+Caching
+-------
+
+A simple caching mechanism is provided to avoid unnecessary work.
+
+``` php
+<?php
+
+use Assetic\Asset\AssetCache;
+use Assetic\Asset\FileAsset;
+use Assetic\Cache\FilesystemCache;
+use Assetic\Filter\Yui;
+
+$yui = new Yui\JsCompressorFilter('/path/to/yuicompressor.jar');
+$js = new AssetCache(
+    new FileAsset('/path/to/some.js', array($yui)),
+    new FilesystemCache('/path/to/cache')
+);
+
+// the YUI compressor will only run on the first call
+$js->dump();
+$js->dump();
+$js->dump();
+```
+
+Static Assets
+-------------
+
+Alternatively you can just write filtered assets to your web directory and be
+done with it.
+
+``` php
+<?php
+
+use Assetic\AssetWriter;
+
+$writer = new AssetWriter('/path/to/web');
+$writer->writeManagerAssets($am);
+```
+
+Twig
+----
+
+To use the Assetic [Twig][3] extension you must register it to your Twig
+environment:
+
+``` php
+<?php
+
+$twig->addExtension(new AsseticExtension($factory, $debug));
+```
+
+Once in place, the extension exposes a stylesheets and a javascripts tag with a syntax similar
+to what the asset factory uses:
+
+``` html+jinja
+{% stylesheets '/path/to/sass/main.sass' filter='sass,?yui_css' output='css/all.css' %}
+    <link href="{{ asset_url }}" type="text/css" rel="stylesheet" />
+{% endstylesheets %}
+```
+
+This example will render one `link` element on the page that includes a URL
+where the filtered asset can be found.
+
+When the extension is in debug mode, this same tag will render multiple `link`
+elements, one for each asset referenced by the `css/src/*.sass` glob. The
+specified filters will still be applied, unless they are marked as optional
+using the `?` prefix.
+
+This behavior can also be triggered by setting a `debug` attribute on the tag:
+
+``` html+jinja
+{% stylesheets 'css/*' debug=true %} ... {% stylesheets %}
+```
+
+These assets need to be written to the web directory so these URLs don't
+return 404 errors.
+
+``` php
+<?php
+
+use Assetic\AssetWriter;
+use Assetic\Extension\Twig\TwigFormulaLoader;
+use Assetic\Extension\Twig\TwigResource;
+use Assetic\Factory\LazyAssetManager;
+
+$am = new LazyAssetManager($factory);
+
+// enable loading assets from twig templates
+$am->setLoader('twig', new TwigFormulaLoader($twig));
+
+// loop through all your templates
+foreach ($templates as $template) {
+    $resource = new TwigResource($twigLoader, $template);
+    $am->addResource($resource, 'twig');
+}
+
+$writer = new AssetWriter('/path/to/web');
+$writer->writeManagerAssets($am);
+```
+

+
+Assetic is based on the Python [webassets][1] library (available on
+[GitHub][2]).

+Building and Dumping Assets
+---------------------------
+
+The is the simplest approach to using Assetic. It involves two steps:
+
+ 1. Create a PHP script in your web directory that uses the Assetic OOP API to
+    create and output an asset.
+ 2. Reference that file from your template.
+
+For example, you could create a file in your web directory at
+`assets/javascripts.php` with the following code:
+
+    use Assetic\Asset\AssetCollection;
+    use Assetic\Asset\FileAsset;
+    use Assetic\Filter\Yui\JsCompressorFilter as YuiCompressorFilter;
+
+    $js = new AssetCollection(array(
+        new FileAsset(__DIR__.'/jquery.js'),
+        new FileAsset(__DIR__.'/application.js'),
+    ), array(
+        new YuiCompressorFilter('/path/to/yuicompressor.jar'),
+    ));
+
+    header('Content-Type: application/js');
+    echo $js->dump();
+
+In your HTML template you would include this generated Javascript using a
+simple `<script>` tag:
+
+    <script src="/assets/javascripts.php"></script>

+In order to use the Assetic OOP API you must first understand the two central
+concepts of Assetic: assets and filters.
+
+### What is an Asset?
+
+As asset is an object that has content and metadata which can be loaded and
+dumped. Your assets will probably fall into three categories: Javascripts,
+stylesheets and images. Most assets will be loaded from files in your
+filesystem, but they can also be loaded via HTTP, a database, from a string,
+or virtually anything else. All that an asset has to do is fulfill Assetic's
+basic asset interface.
+
+### What is a Filter?
+
+A filter is an object that acts upon an asset's content when that asset is
+loaded and/or dumped. Similar to assets, a filter can do virtually anything,
+as long as it implements Assetic's filter interface. 
+
+Here is a list of some of the tools that can be applied to assets using a
+filter:
+
+ * CoffeeScript
+ * CssEmbed
+ * CssMin
+ * Google Closure Compiler
+ * jpegoptim
+ * jpegtran
+ * Less
+ * LessPHP
+ * optipng
+ * Packager
+ * pngout
+ * SASS
+ * Sprockets (version 1)
+ * Stylus
+ * YUI Compressor
+
+### Using Assets and Filters
+
+You need to start by creating an asset object. This will probably mean
+instantiating a `FileAsset` instance, which takes a filesystem path as its
+first argument:
+
+    $asset = new Assetic\Asset\FileAsset('/path/to/main.css');
+
+Once you have an asset you can begin adding filters to it by calling
+`ensureFilter()`. For example, you can add a filter that applies the YUI
+Compressor to the contents of the asset:
+
+    $yui = new Assetic\Filter\Yui\CssCompressorFilter('/path/to/yui.jar');
+    $asset->ensureFilter($yui);
+
+Once you've added as many filters as you'd like you can output the finished
+asset to the browser:
+
+    header('Content-Type: text/css');
+    echo $asset->dump();
+
+### Asset Collections
+
+It is a good idea to combine assets of the same type into a single file to
+avoid unnecessary HTTP requests. You can do this in Assetic using the
+`AssetCollection` class. This class is just like any other asset in Assetic's
+eyes as it implements the asset interface, but under the hood it allows you to
+combine multiple assets into one.
+
+    use Assetic\Asset\AssetCollection;
+
+    $asset = new AssetCollection(array(
+        new FileAsset('/path/to/js/jquery.js'),
+        new FileAsset('/path/to/js/jquery.plugin.js'),
+        new FileAsset('/path/to/js/application.js'),
+    ));
+
+### Nested Asset Collections
+
+The collection class implements the asset interface and all assets passed into
+a collection must implement the same interface, which means you can easily
+nest collections within one another:
+
+    use Assetic\Asset\AssetCollection;
+    use Assetic\Asset\GlobAsset;
+    use Assetic\Asset\HttpAsset;
+
+    $asset = new AssetCollection(array(
+        new HttpAsset('http://example.com/jquery.min.js'),
+        new GlobAsset('/path/to/js/*'),
+    ));
+
+The `HttpAsset` class is a special asset class that loads a file over HTTP;
+`GlobAsset` is a special asset collection class that loads files based on a
+filesystem glob -- both implement the asset interface.
+
+This concept of nesting asset collection become even more powerful when you
+start applying different sets of filters to each collection. Imagine some of
+your application's stylesheets are written in SASS, while some are written in
+vanilla CSS. You can combine all of these into one seamless CSS asset:
+
+    use Assetic\Asset\AssetCollection;
+    use Assetic\Asset\GlobAsset;
+    use Assetic\Filter\SassFilter;
+    use Assetic\Filter\Yui\CssCompressorFilter;
+
+    $css = new AssetCollection(array(
+        new GlobAsset('/path/to/sass/*.sass', array(new SassFilter())),
+        new GlobAsset('/path/to/css/*.css'),
+    ), array(
+        new YuiCompressorFilter('/path/to/yuicompressor.jar'),
+    ));
+
+You'll notice I've also applied the YUI compressor filter to the combined
+asset so all CSS will be minified.
+
+### Iterating over an Asset Collection
+
+Once you have an asset collection you can iterate over it like you would a
+plain old PHP array:
+
+    echo "Source paths:\n";
+    foreach ($collection as $asset) {
+        echo ' - '.$asset->getSourcePath()."\n";
+    }
+
+The asset collection iterates recursively, which means you will only see the
+"leaf" assets during iteration. Iteration also includes a smart filter which
+ensures you only see each asset once, even if the same asset has been included
+multiple times.

+Defining Assets "On The Fly"
+----------------------------
+
+The second approach to using Assetic involves defining your application's
+assets "on the fly" in your templates, instead of in an isolated PHP file.
+Using this approach, your PHP template would look something like this:
+
+    <script src="<?php echo assetic_javascripts('js/*', 'yui_js') ?>"></script>
+
+This call to `assetic_javascripts()` serves a dual purpose. It will be read by
+the Assetic "formula loader" which will extract an asset "formula" that can be
+used to build, dump and output the asset. It will also be executed when the
+template is rendered, at which time the path to the output asset is output.
+
+Assetic includes the following templating helper functions:
+
+ * `assetic_image()`
+ * `assetic_javascripts()`
+ * `assetic_stylesheets()`
+
+Defining assets on the fly is a much more sophisticated technique and
+therefore relies on services to do the heavy lifting. The main one being the
+asset factory.
+
+### Asset Factory
+
+The asset factory knows how to create asset objects using only arrays and
+scalar values as input. This is the same string syntax used by the `assetic_*`
+template helper functions.
+
+    use Assetic\Factory\AssetFactory;
+
+    $factory = new AssetFactory('/path/to/web');
+    $js = $factory->createAsset(array(
+        'js/jquery.js',
+        'js/jquery.plugin.js',
+        'js/application.js',
+    ));
+
+### Filter Manager
+
+You can also apply filters to asset created by the factory. To do this you
+must setup a `FilterManager`, which organizes filters by a name.
+
+    use Assetic\FilterManager;
+    use Assetic\Filter\GoogleClosure\ApiFilter as ClosureFilter;
+
+    $fm = new FilterManager();
+    $fm->set('closure', new ClosureFilter());
+    $factory->setFilterManager($fm);
+
+    $js = $factory->createAsset('js/*', 'closure');
+
+This code creates an instance of the Google Closure Compiler filter and
+assigns it the name `closure` using a filter manager. This filter manager is
+then injected into the asset factory, making the filter available as `closure`
+when creating assets.
+
+### Debug Mode
+
+The asset factory also introduces the concept of a debug mode. This mode
+allows you to omit certain filters from assets the factory creates depending
+on whether it is enabled or not.
+
+For example, the YUI Compressor is awesome, but it is only appropriate in a
+production environment as it is very difficult to debug minified Javascript.
+
+    use Asset\Factory\AssetFactory;
+
+    $factory = new AssetFactory('/path/to/web', true); // debug mode is on
+    $factory->setFilterManager($fm);
+    $js = $factory->createAsset('js/*', '?closure');
+
+By prefixing the `closure` filter's name with a question mark, we are telling
+the factory this filter is optional and should only be applied with debug mode
+is off.
+
+### Asset Manager and Asset References
+
+The asset factory provides another special string syntax that allows you to
+reference assets you defined elsewhere. These are called "asset references"
+and involve an asset manager which, similar to the filter manager, organizes
+assets by name.
+
+    use Assetic\AssetManager;
+    use Assetic\Asset\FileAsset;
+    use Assetic\Factory\AssetFactory;
+
+    $am = new AssetManager();
+    $am->set('jquery', new FileAsset('/path/to/jquery.js'));
+
+    $factory = new AssetFactory('/path/to/web');
+    $factory->setAssetManager($am);
+
+    $js = $factory->createAsset(array(
+        '@jquery',
+        'js/application.js',
+    ));
+
+### Extracting Assets from Templates
+
+Once you've defined a set of assets in your templates you must use the
+"formula loader" service to extract these asset definitions.
+
+    use Assetic\Factory\Loader\FunctionCallsFormulaLoader;
+    use Assetic\Factory\Resource\FileResource;
+
+    $loader = new FunctionCallsFormulaLoader($factory);
+    $formulae = $loader->load(new FileResource('/path/to/template.php'));
+
+These asset formulae aren't much use by themselves. They each include just
+enough information for the asset factory to create the intended asset object.
+In order for these to be useful they must be wrapped in the special
+`LazyAssetManager`.
+
+### The Lazy Asset Manager
+
+This service is a composition of the asset factory and one or more formula
+loaders. It acts as the glue between these services behind the scenes, but can
+be used just like a normal asset manager on the surface.
+
+    use Assetic\Asset\FileAsset;
+    use Assetic\Factory\LazyAssetManager;
+    use Assetic\Factory\Loader\FunctionCallsFormulaLoader;
+    use Assetic\Factory\Resource\DirectoryResource;
+
+    $am = new LazyAssetManager($factory);

+    $am->setLoader('php', new FunctionCallsFormulaLoader($factory));
+    $am->addResource(new DirectoryResource('/path/to/templates', '/\.php$/'), 'php');
+
+### Asset Writer
+
+Finally, once you've create an asset manager that knows about every asset
+you've defined in your templates, you must use an asset writer to actually
+create the files your templates are going to be referencing.
+
+    use Assetic\AssetWriter;
+
+    $writer = new AssetWriter('/path/to/web');
+    $writer->writeManagerAssets($am);
+
+After running this script, all of the assets in your asset manager will be
+loaded into memory, filtered with their configured filters and dumped to your
+web directory as static files, ready to be served.

+What is Assetic?
+----------------
+
+Assetic is an asset management framework for PHP 5.3. Assetic enables you to
+use a variety of third party tools that will help bring order to your
+application's Javascripts, stylesheets and images.
+
+How Do I Use Assetic?
+---------------------
+
+There are two distinct approaches you can take when using Assetic:
+
+ 1. Build, dump and output assets in PHP files that you reference directly
+    from your templates
+ 2. Defining assets in your templates ("on the fly") and use a loader to
+    extract, dump and output them
+
+The first approach is simpler, but the second, with all its moving parts,
+offers more flexibility and opportunity for optimization.

+アセットのビルドとダンプ
+---------------------------
+
+Asseticを使う一番単純な方法は、次の2ステップからなります。
+
+ 1. 公開領域内にPHPスクリプトを作成し、Assetic OOP APIを使用してアセットの作成・出力を行う
+ 2. テンプレートから上記のファイルを参照する
+
+例えば、公開領域内に`assets/javascripts.php`ファイルを作成し、
+下記のようなコードを記述します。
+
+    use Assetic\Asset\AssetCollection;
+    use Assetic\Asset\FileAsset;
+    use Assetic\Filter\Yui\JsCompressorFilter as YuiCompressorFilter;
+
+    $js = new AssetCollection(array(
+        new FileAsset(__DIR__.'/jquery.js'),
+        new FileAsset(__DIR__.'/application.js'),
+    ), array(
+        new YuiCompressorFilter('/path/to/yuicompressor.jar'),
+    ));
+
+    header('Content-Type: application/js');
+    echo $js->dump();
+
+HTMLテンプレート側では、単に`<script>`タグを用いて、生成されたJavascriptをインクルードすることになります。

+Assetic OOP APIを使用するためには、まず、[アセット」と「フィルタ」の2つの重要なコンセプトを理解する必要があります。
+
+### アセット
+
+アセットとは、読み込み、及びダンプが可能な、コンテンツとメタデータを内包しているオブジェクトの事を指します。
+大体の場合において3つのカテゴリー、すなわち、Javascriptとスタイルシート、画像のどれかに属することになるでしょう。
+読み込みの方法としては、ファイルシステムからがほとんどですが、
+HTTPやデータベース経由でも、文字列としてでも読み込みが可能で、事実上あらゆるものが読み込み可能です。
+Asseticのアセットインターフェースを満足させさえすれば良いのです。
+
+
+### フィルタ
+ 
+フィルタは、アセットが読み込まれる、かつ/もしくは、ダンプされる際に、
+アセットコンテンツに対して作用するオブジェクトです。
+アセットと同様に、Asseticのフィルタインターフェースを実装することで、
+どのような作用も可能になります。
+
+フィルタを用いて、アセットに適用できるツール群の一覧です。
+
+ * CoffeeScript
+ * CssEmbed
+ * CssMin
+ * Google Closure Compiler
+ * jpegoptim
+ * jpegtran
+ * Less
+ * LessPHP
+ * optipng
+ * Packager
+ * pngout
+ * SASS
+ * Sprockets (version 1)
+ * Stylus
+ * YUI Compressor
+
+
+### アセットとフィルタの使用
+
+まずはアセットオブジェクトを作成することから始まります。
+多くの場合は`FileAsset`をインスタンス化し、ファイルシステムのパスを第一引数に渡します。
+
+    $asset = new Assetic\Asset\FileAsset('/path/to/main.css');
+
+アセットオブジェクトを作成したら、`ensureFilter()`を呼び、フィルタを追加します。
+例えば、アセットコンテンツにYUI Compressorを適用してみましょう。
+
+    $yui = new Assetic\Filter\Yui\CssCompressorFilter('/path/to/yui.jar');
+    $asset->ensureFilter($yui);
+
+任意のフィルタを追加したら、完成したアセットをブラウザに出力してみましょう。
+
+    header('Content-Type: text/css');
+    echo $asset->dump();
+
+### アセットコレクション
+
+1つのファイルに同じ種類のアセットをまとめて、不要なHTTPリクエストを抑えてみるのも良いでしょう。
+Asseticでは`AsseticColletion`クラスを使用することで可能となります。
+Assetic内部的には、このクラス自体は他のアセットと同様に、アセットインターフェースを実装したものですが、
+複数のアセットを1つにまとめることが可能になります。
+
+    use Assetic\Asset\AssetCollection;
+
+    $asset = new AssetCollection(array(
+        new FileAsset('/path/to/js/jquery.js'),
+        new FileAsset('/path/to/js/jquery.plugin.js'),
+        new FileAsset('/path/to/js/application.js'),
+    ));
+
+### ネストしたアセットコレクション
+
+コレクションクラス自体がアセットインターフェースを実装し、コレクション内のアセットも同様に
+アセットインターフェースを実装しているので、簡単にネストすることができます。
+
+    use Assetic\Asset\AssetCollection;
+    use Assetic\Asset\GlobAsset;
+    use Assetic\Asset\HttpAsset;
+
+    $asset = new AssetCollection(array(
+        new HttpAsset('http://example.com/jquery.min.js'),
+        new GlobAsset('/path/to/js/*'),
+    ));
+
+`HttpAsset`は、HTTP経由でファイルを読み込むアセットクラス。
+`GlobAsset`は、ファイルシステムのglobを基にファイル群を読み込むアセットコレクションクラス。
+両者ともにアセットインターフェースを実装しています。
+
+このネストしたアセットコレクションという概念は、コレクションそれぞれに異なる
+フィルタ群を適用しようとしたときに、効果を発揮します。
+例えば、スタイルシートがSAASで記述されたものと、vanilla CSSを用いて記述されたものからなる
+アプリケーションを考えた場合、次のようにして、全てを1つのシームレスなCSSアセットにまとめることができます。
+
+    use Assetic\Asset\AssetCollection;
+    use Assetic\Asset\GlobAsset;
+    use Assetic\Filter\SassFilter;
+    use Assetic\Filter\Yui\CssCompressorFilter;
+
+    $css = new AssetCollection(array(
+        new GlobAsset('/path/to/sass/*.sass', array(new SassFilter())),
+        new GlobAsset('/path/to/css/*.css'),
+    ), array(
+        new YuiCompressorFilter('/path/to/yuicompressor.jar'),
+    ));
+
+上記の例では、1つにまとめられたCSSを、さらにYUI compressorフィルタを適用することで、全体を圧縮しています。
+
+### アセットコレクションのイテレーション
+
+アセットコレクションは、旧来のPHP配列のように、イテレートできます。
+
+    echo "Source paths:\n";
+    foreach ($collection as $asset) {
+        echo ' - '.$asset->getSourcePath()."\n";
+    }
+
+アセットコレクションのイテレーションは再帰的で、「葉」にあたるアセットの取得を行います。
+また、気の利いたフィルタを内蔵しているので、同じアセットがコレクション内に複数存在する場合でも、
+一度だけのインクルードが保証されます。

+アセットの「オンザフライ」な定義
+----------------------------------------
+
+Asseticの使用方法二つ目は、独立したPHPファイルを使用する代わりに、
+テンプレートで「オンザフライ」にアセット定義をする方法です。
+このアプローチでは、PHPテンプレートは下記のようになります。
+
+    <script src="<?php echo assetic_javascripts('js/*', 'yui_js') ?>"></script>
+
+`assetic_javascripts()`の呼び出しは2つの目的を兼ねています。
+まず、「フォーミュラローダー」により走査され、アセットの構築、ダンプ、及び出力を行うための「フォーミュラ(処方箋)」が抽出されます。
+また、テンプレートのレンダー時にも実行され、アセットの出力パスが出力されます。
+
+Asseticには下記のようなヘルパー関数があります。
+
+ * `assetic_image()`
+ * `assetic_javascripts()`
+ * `assetic_stylesheets()`
+
+アセットをオンザフライに定義するということは、より高度なテクニックであり、
+そのため、重い仕事をするサービスに依存することになります。
+そのうちの重要なものがアセットファクトリです。
+
+### アセットファクトリ
+
+アセットファクトリは、アセットオブジェクトを、配列とスカラ値のみから、
+どのように作成するのか把握しています。
+`assetic_*`ヘルパー関数で使用する記法と同様のものとなります。
+
+    use Assetic\Factory\AssetFactory;
+
+    $factory = new AssetFactory('/path/to/web');
+    $js = $factory->createAsset(array(
+        'js/jquery.js',
+        'js/jquery.plugin.js',
+        'js/application.js',
+    ));
+
+### フィルタマネージャー
+
+ファクトリによって作成されたアセットに対しても、フィルタを適用することができます。
+そのためには、`FilterManager`を設定して、名前を定義しフィルタを構成します。
+
+    use Assetic\FilterManager;
+    use Assetic\Filter\GoogleClosure\ApiFilter as ClosureFilter;
+
+    $fm = new FilterManager();
+    $fm->set('closure', new ClosureFilter());
+    $factory->setFilterManager($fm);
+
+    $js = $factory->createAsset('js/*', 'closure');
+
+上記の例では、Google Closure Compilerフィルタをインスタンス化し、
+フィルタマネージャーを通じて`closure`という名前をつけています。
+このフィルタマネージャーをアセットファクトリに渡すことで、
+アセット作成時には、`closure`という名前でフィルタを使用できるようになります。
+
+### デバッグモード
+
+アセットファクトリは、デバッグモードというコンセプトも取り入れており、
+デバッグモードの設定により、ファクトリが作成するアセットから、
+特定のフィルタを除外することができます。
+
+たとえば、YUI Compressorは大変素晴らしいのですが、圧縮されたJavascriptを
+デバッグするのは大変難しく、プロダクション環境でのみの使用が適切でしょう。
+
+    use Asset\Factory\AssetFactory;
+
+    $factory = new AssetFactory('/path/to/web', true); // デバッグモードON
+    $factory->setFilterManager($fm);
+    $js = $factory->createAsset('js/*', '?closure');
+
+フィルタ名`closure`の前にクエスチョンマークを記述すると、ファクトリに対して、
+このフィルタはオプションであり、
+デバッグモードがOFFの時にのみ適用するように通知することができます。
+
+### アセットマネージャーとアセットリファレンス
+
+アセットファクトリにはもう一つ特別な記法があり、別の場所で定義した
+アセットを参照することができるようになります。
+これを「アセットリファレンス」と呼び、アセットマネージャーを通じて、
+フィルタマネージャーと同様の、名前によるアセットの構成が可能です。
+
+    use Assetic\AssetManager;
+    use Assetic\Asset\FileAsset;
+    use Assetic\Factory\AssetFactory;
+
+    $am = new AssetManager();
+    $am->set('jquery', new FileAsset('/path/to/jquery.js'));
+
+    $factory = new AssetFactory('/path/to/web');
+    $factory->setAssetManager($am);
+
+    $js = $factory->createAsset(array(
+        '@jquery',
+        'js/application.js',
+    ));
+
+### テンプレートからのアセット抽出
+
+テンプレート内でアセット群を定義したら、「フォーミュラローダー」サービスを使用して、
+アセットの定義を抽出します。
+
+    use Assetic\Factory\Loader\FunctionCallsFormulaLoader;
+    use Assetic\Factory\Resource\FileResource;
+
+    $loader = new FunctionCallsFormulaLoader($factory);
+    $formulae = $loader->load(new FileResource('/path/to/template.php'));
+
+これらのフォーミュラ自体は、それ自体で使途はあまりなく、
+アセットファクトリが目的のアセットオブジェクトを作成するに足る情報しか持っていません。
+`LazyAssetManager`でラップすることで有益なものとなります。
+
+### レイジーなアセットマネージャー
+
+このサービスは、アセットファクトリと、1つ以上のフォーミュラローダーから成っており、
+裏方のサービス間のグルとして動作しますが、表面上では、通常のアセットマネージャーと同じように使用することができます。
+
+    use Assetic\Asset\FileAsset;
+    use Assetic\Factory\LazyAssetManager;
+    use Assetic\Factory\Loader\FunctionCallsFormulaLoader;
+    use Assetic\Factory\Resource\DirectoryResource;
+
+    $am = new LazyAssetManager($factory);
+    $am->set('jquery', new FileAsset('/path/to/jquery.js'));
+    $am->setLoader('php', new FunctionCallsFormulaLoader($factory));
+    $am->addResource(new DirectoryResource('/path/to/templates', '/\.php$/'), 'php');
+
+### アセットライター
+
+作成したアセットマネージャーが、テンプレート内で定義した全てのアセットを把握したら、
+アセットライターを使用して、テンプレートが参照することになる実際のファイルを作成します。
+
+    use Assetic\AssetWriter;
+
+    $writer = new AssetWriter('/path/to/web');
+    $writer->writeManagerAssets($am);
+
+上記のスクリプトを実行すると、アセットマネージャー内のすべてのアセットがメモリに読み込まれ、
+指定したフィルタが適用された後、公開領域に静的ファイルとしてダンプされ、準備完了となります。

+Asseticとは
+-----------------
+
+Asseticは、PHP5.3用のアセット管理フレームワークです。
+Asseticを導入することで、Javascriptやスタイルシート、画像をコントロールする
+様々なサードパーティー製のツールを使用できるようになります。
+
+Asseticの使用方法
+---------------------
+
+2つの異なるアプローチがあります。
+
+ 1. アセットのビルド、ダンプ、出力をPHPファイルで行い、テンプレートからそのファイルを直接参照する方法
+ 2. テンプレート内でアセットを(「オンザフライ」に)定義し、抽出やダンプ、出力にローダーを使用する方法
+
+前者はいくらかシンプルである一方、後者は動的で柔軟性に富み、最適化が可能となります。
