+=============
+
+A fast and simple streaming zip file downloader for PHP. Using this library will
+save you from having to write the Zip to disk. You can directly send it to the
+user, which is much faster. It can work with S3 buckets or any PSR7 Stream.
+

+
+Installation
+---------------
+
+Simply add a dependency on ``maennchen/zipstream-php`` to your project's
+``composer.json`` file if you use Composer to manage the dependencies of your
+project. Use following command to add the package to your project's dependencies:
+
+.. code-block:: sh
+ composer require maennchen/zipstream-php
+
+Usage Intro
+---------------
+
+Here's a simple example:
+
+.. code-block:: php
+
+ // Autoload the dependencies
+ require 'vendor/autoload.php';
+
+ // enable output of HTTP headers
+ $options = new ZipStream\Option\Archive();
+ $options->setSendHttpHeaders(true);
+
+ // create a new zipstream object
+ $zip = new ZipStream\ZipStream('example.zip', $options);
+
+ // create a file named 'hello.txt'
+ $zip->addFile('hello.txt', 'This is the contents of hello.txt');
+
+ // add a file named 'some_image.jpg' from a local file 'path/to/image.jpg'
+ $zip->addFileFromPath('some_image.jpg', 'path/to/image.jpg');
+
+ // add a file named 'goodbye.txt' from an open stream resource
+ $fp = tmpfile();
+ fwrite($fp, 'The quick brown fox jumped over the lazy dog.');
+ rewind($fp);
+ $zip->addFileFromStream('goodbye.txt', $fp);
+ fclose($fp);
+
+ // finish the zip stream
+ $zip->finish();
+
+You can also add comments, modify file timestamps, and customize (or
+disable) the HTTP headers. It is also possible to specify the storage method
+when adding files, the current default storage method is ``DEFLATE``
+i.e files are stored with Compression mode 0x08.
+
+Known Issues
+---------------
+
+The native Mac OS archive extraction tool prior to macOS 10.15 might not open
+archives in some conditions. A workaround is to disable the Zip64 feature with
+the option ``enableZip64: false``. This limits the archive to 4 Gb and 64k files
+but will allow users on macOS 10.14 and below to open them without issue.
+See `#116 <https://github.com/maennchen/ZipStream-PHP/issues/146>`_.
+
+The linux ``unzip`` utility might not handle properly unicode characters.
+It is recommended to extract with another tool like
+`7-zip <https://www.7-zip.org/>`_.
+See `#146 <https://github.com/maennchen/ZipStream-PHP/issues/146>`_.
+
+It is the responsability of the client code to make sure that files are not
+saved with the same path, as it is not possible for the library to figure it out
+while streaming a zip.
+See `#154 <https://github.com/maennchen/ZipStream-PHP/issues/154>`_.

+ * Usage:

+ * Streaming zip archives is a simple, three-step process:
+ *
+ * 1. Create the zip stream:
+ *
+ * $zip = new ZipStream('example.zip');
+ *
+ * 2. Add one or more files to the archive:
+ *
+ * * add first file
+ * $data = file_get_contents('some_file.gif');
+ * $zip->addFile('some_file.gif', $data);
+ *
+ * * add second file
+ * $data = file_get_contents('some_file.gif');
+ * $zip->addFile('another_file.png', $data);
+ *
+ * 3. Finish the zip stream:
+ *
+ * $zip->finish();
+ *
+ * You can also add an archive comment, add comments to individual files,
+ * and adjust the timestamp of files. See the API documentation for each
+ * method below for additional information.

+ * Large File Support:
+ *
+ * By default, the method addFileFromPath() will send send files
+ * larger than 20 megabytes along raw rather than attempting to
+ * compress them. You can change both the maximum size and the
+ * compression behavior using the largeFile* options above, with the
+ * following caveats:
+ *
+ * * For "small" files (e.g. files smaller than largeFileSize), the
+ * memory use can be up to twice that of the actual file. In other
+ * words, adding a 10 megabyte file to the archive could potentially
+ * occupy 20 megabytes of memory.
+ *
+ * * Enabling compression on large files (e.g. files larger than
+ * large_file_size) is extremely slow, because ZipStream has to pass
+ * over the large file once to calculate header information, and then
+ * again to compress and send the actual data.
+ *
+ * Examples:
+ *
+ * // create a new zip file named 'foo.zip'
+ * $zip = new ZipStream('foo.zip');
+ *
+ * // create a new zip file named 'bar.zip' with a comment
+ * $opt->setComment = 'this is a comment for the zip file.';
+ * $zip = new ZipStream('bar.zip', $opt);
+ *
+ * Notes:
+ *
+ * In order to let this library send HTTP headers, a filename must be given
+ * _and_ the option `sendHttpHeaders` must be `true`. This behavior is to
+ * allow software to send its own headers (including the filename), and
