-Favicon fetcher
-===============
-
-Find and download the favicon
------------------------------
-
-```php
-use PicoFeed\Reader\Favicon;
-
-$favicon = new Favicon;
-
-// The icon link is https://bits.wikimedia.org/favicon/wikipedia.ico
-$icon_link = $favicon->find('https://en.wikipedia.org/');
-$icon_content = $favicon->getContent();
-```
-
-PicoFeed will try first to find the favicon from the meta tags and fallback to the `favicon.ico` located in the website's root if nothing is found.
-
-- `Favicon::find()` returns the favicon absolute url or an empty string if nothing is found.
-- `Favicon::getContent()` returns the favicon file content (binary content)
-
-When the HTML page is parsed, relative links and protocol relative links are converted to absolute url.
-
-Get Favicon file type
----------------------
-
-It's possible to fetch the image type, this information come from the Content-Type HTTP header:
-
-```php
-$favicon = new Favicon;
-$favicon->find('http://example.net/');
-
-echo $favicon->getType();
-
-// Will output the content type, by example "image/png"
-```
-
-Get the Favicon as Data URI
----------------------------
-
-You can also get the whole image as Data URI.
-It's useful if you want to store the icon in your database and avoid too many HTTP requests.
-
-```php
-$favicon = new Favicon;
-$favicon->find('http://example.net/');
-
-echo $favicon->getDataUri();
-
-// Output something like that: data:image/png;base64,iVBORw0KGgoAAAANSUh.....
-```
-
-See: http://en.wikipedia.org/wiki/Data_URI_scheme
-
-Check if a favicon link exists
-------------------------------
-
-```php
-use PicoFeed\Reader\Favicon;
-
-$favicon = new Favicon;
-
-// Return true if the file exists
-var_dump($favicon->exists('http://php.net/favicon.ico'));
-```
-
-Use personalized HTTP settings
-------------------------------
-
-Like other classes, the Favicon class support the Config object as constructor argument:
-
-```php
-use PicoFeed\Config\Config;
-use PicoFeed\Reader\Favicon;
-
-$config = new Config;
-$config->setClientUserAgent('My RSS Reader');
-
-$favicon = new Favicon($config);
-$favicon->find('https://github.com');
-```
