-	 *    the appropriate handler installed or when a file type is
-	 *    unsupported. Can be any text or HTML. Defaults to blank.
-	 * - `altclass` (string): If a file type is unsupported, the end-user will
-	 *    see the alt text (above) linked directly to the content. That link
-	 *    will have this value as its class name. Defaults to blank.
-	 * - `audio` (string): This is an image that should be used as a
-	 *    placeholder for audio files before they're loaded (QuickTime-only).
-	 *    Can be any relative or absolute URL. Defaults to blank.
-	 * - `bgcolor` (string): The background color for the media, if not
-	 *    already transparent. Defaults to `#ffffff`.
-	 * - `height` (integer): The height of the embedded media. Accepts any
-	 *    numeric pixel value (such as `360`) or `auto`. Defaults to `auto`,
-	 *    and it is recommended that you use this default.
-	 * - `loop` (boolean): Do you want the media to loop when it's done?
-	 *    Defaults to `false`.
-	 * - `mediaplayer` (string): The location of the included
-	 *    `mediaplayer.swf` file. This allows for the playback of Flash Video
-	 *    (`.flv`) files, and is the default handler for non-Odeo MP3's.
-	 *    Defaults to blank.
-	 * - `video` (string): This is an image that should be used as a
-	 *    placeholder for video files before they're loaded (QuickTime-only).
-	 *    Can be any relative or absolute URL. Defaults to blank.
-	 * - `width` (integer): The width of the embedded media. Accepts any
-	 *    numeric pixel value (such as `480`) or `auto`. Defaults to `auto`,
-	 *    and it is recommended that you use this default.
-	 * - `widescreen` (boolean): Is the enclosure widescreen or standard?
-	 *    This applies only to video enclosures, and will automatically resize
-	 *    the content appropriately.  Defaults to `false`, implying 4:3 mode.
-	 *
-	 * Note: Non-widescreen (4:3) mode with `width` and `height` set to `auto`
-	 * will default to 480x360 video resolution.  Widescreen (16:9) mode with
-	 * `width` and `height` set to `auto` will default to 480x270 video resolution.
-	 *
-	 * @todo If the dimensions for media:content are defined, use them when width/height are set to 'auto'.

+## FreshRSS fork
+
+[This repository `FreshRSS/simplepie`](https://github.com/FreshRSS/simplepie) is a fork of the [main repository `simplepie/simplepie`](https://github.com/simplepie/simplepie)
+intended to be used for [FreshRSS](https://github.com/FreshRSS/FreshRSS), which is a free, self-hostable news aggregator.
+
+The default branch [`freshrss`](https://github.com/FreshRSS/simplepie/tree/freshrss) is the one used in [the FreshRSS codebase](https://github.com/FreshRSS/FreshRSS/tree/edge/lib/simplepie).
+
+This allows in particular to use fixes and patches, which have not (yet) been submitted upstream or not (yet) merged upstream.

+SimplePie
+=========
+
+SimplePie is a very fast and easy-to-use class, written in PHP, that puts the
+'simple' back into 'really simple syndication'.  Flexible enough to suit
+beginners and veterans alike, SimplePie is focused on [speed, ease of use,
+compatibility and standards compliance][what_is].
+
+[what_is]: http://simplepie.org/wiki/faq/what_is_simplepie
+
+
+Requirements
+------------
+* PHP 7.2+ (Required since SimplePie 1.8.0)
+* libxml2 (certain 2.7.x releases are too buggy for words, and will crash)
+* One of iconv, mbstring or intl extensions
+* Optionally, intl extension, [symfony/polyfill-intl-idn](https://github.com/symfony/polyfill-intl-idn) or cURL extension built with IDN support to support IDNs
+* cURL or fsockopen()
+* PCRE support
+
+PSR-18: HTTP Client support
+--------------
+
+Since SimplePie 1.9.0 you can use a [PSR-18](https://www.php-fig.org/psr/psr-18/) HTTP client like [Guzzle](https://guzzlephp.org)
+or [every other implementation](https://packagist.org/providers/psr/http-client-implementation).
+Please note that you would also need [PSR-17](https://www.php-fig.org/psr/psr-17/) implementations of `RequestFactoryInterface` and an `UriFactoryInterface` implementation.
+
+```php
+$simplepie = new \SimplePie\SimplePie();
+$simplepie->set_http_client(
+    new \GuzzleHttp\Client(),
+    new \GuzzleHttp\Psr7\HttpFactory(),
+    new \GuzzleHttp\Psr7\HttpFactory(),
+);
+```
+
+PSR-16: Caching support
+--------------
+
+Since SimplePie 1.8.0 you can use the [PSR-16](https://www.php-fig.org/psr/psr-16/) cache from
+[Symfony](https://symfony.com/doc/current/components/cache.html)
+or [every other implementation](https://packagist.org/providers/psr/simple-cache-implementation).
+
+```php
+$simplepie = new \SimplePie\SimplePie();
+$simplepie->set_cache(
+    new \Symfony\Component\Cache\Psr16Cache(
+        new \Symfony\Component\Cache\Adapter\FilesystemAdapter()
+    ),
+);
+```
+
+What comes in the package?
+--------------------------
+1. `src/` - SimplePie classes for use with the autoloader
+2. `autoloader.php` - The SimplePie Autoloader if you want to use the separate
+   file version.
+3. `README.markdown` - This document.
+4. `LICENSES/BSD-3-Clause.txt` - A copy of the BSD license.
+5. `compatibility_test/` - The SimplePie compatibility test that checks your
+   server for required settings.
+6. `demo/` - A basic feed reader demo that shows off some of SimplePie's more
+   noticeable features.
+7. `build/` - Scripts related to generating pieces of SimplePie
+8. `test/` - SimplePie's unit test suite.
+
+### Where's `simplepie.inc`?
+Since SimplePie 1.3, we've split the classes into separate files to make it easier
+to maintain and use.
+
+If you'd like a single monolithic file, see the assets in the
+[releases](https://github.com/simplepie/simplepie/releases), or you can
+run `php build/compile.php` to generate `SimplePie.compiled.php` yourself.
+
+To start the demo
+-----------------
+1. Upload this package to your webserver.
+2. Make sure that the cache folder inside of the demo folder is server-writable.
+3. Navigate your browser to the demo folder.
+
+
+Need support?
+-------------
+For further setup and install documentation, function references, etc., visit
+[the wiki][wiki]. If you're using the latest version off GitHub, you can also
+check out the [API documentation][].
+
+If you can't find an answer to your question in the documentation, head on over
+to one of our [support channels][]. For bug reports and feature requests, visit
+the [issue tracker][].

+
+
+Project status
+--------------
+SimplePie is currently maintained by Malcolm Blaney.
+
+As an open source project, SimplePie is maintained on a somewhat sporadic basis.
+This means that feature requests may not be fulfilled straight away, as time has
+to be prioritized.
+
+If you'd like to contribute to SimplePie, the best way to get started is to fork
+the project on GitHub and send pull requests for patches. When doing so, please
+be aware of our [coding standards](http://simplepie.org/wiki/misc/coding_standards).
+
+The main development for the next minor release happens in `master` branch.
+Please create your pull requests primarily against this branch.
+
+We do not actively provide bug fixes or security fixes for older versions. Nevertheless,
+you are welcome to create backport PRs if you still need support for older PHP versions.
+Please open your PR against the appropriate branch.
