+PHPArchive - Pure PHP ZIP and TAR handling
+==========================================
+
+This library allows to handle new ZIP and TAR archives without the need for any special PHP extensions (gz and bzip are
+needed for compression). It can create new files or extract existing ones.
+
+To keep things simple, the modification (adding or removing files) of existing archives is not supported.
+
+[![Build Status](https://travis-ci.org/splitbrain/php-archive.svg)](https://travis-ci.org/splitbrain/php-archive)
+
+Install
+-------
+
+Use composer:
+
+```php composer.phar require splitbrain/php-archive```
+
+Usage
+-----
+
+The usage for the Zip and Tar classes are basically the same. Here are some
+examples for working with TARs to get you started.
+
+Check the [API docs](https://splitbrain.github.io/php-archive/) for more
+info.
+
+
+```php
+require_once 'vendor/autoload.php';
+use splitbrain\PHPArchive\Tar;
+
+// To list the contents of an existing TAR archive, open() it and use
+// contents() on it:
+$tar = new Tar();
+$tar->open('myfile.tgz');
+$toc = $tar->contents();
+print_r($toc); // array of FileInfo objects
+
+// To extract the contents of an existing TAR archive, open() it and use
+// extract() on it:
+$tar = new Tar();
+$tar->open('myfile.tgz');
+$tar->extract('/tmp');
+
+// To create a new TAR archive directly on the filesystem (low memory
+// requirements), create() it:
+$tar = new Tar();
+$tar->create('myfile.tgz');
+$tar->addFile(...);
+$tar->addData(...);
+...
+$tar->close();
+
+// To create a TAR archive directly in memory, create() it, add*()
+// files and then either save() or getArchive() it:
+$tar = new Tar();
+$tar->setCompression(9, Archive::COMPRESS_BZIP);
+$tar->create();
+$tar->addFile(...);
+$tar->addData(...);
+...
+$tar->save('myfile.tbz'); // compresses and saves it
+echo $tar->getArchive(); // compresses and returns it
+```
+
+Differences between Tar and Zip: Tars are compressed as a whole, while Zips compress each file individually. Therefore
+you can call ```setCompression``` before each ```addFile()``` and ```addData()``` function call.
+
+The FileInfo class can be used to specify additional info like ownership or permissions when adding a file to
+an archive.
