+PHP wrapper for `smbclient` and [`libsmbclient-php`](https://github.com/eduardok/libsmbclient-php)
+
+- Reuses a single `smbclient` instance for multiple requests
+- Doesn't leak the password to the process list
+- Simple 1-on-1 mapping of SMB commands
+- A stream-based api to remove the need for temporary files
+- Support for using libsmbclient directly trough [`libsmbclient-php`](https://github.com/eduardok/libsmbclient-php)
+
+Examples
+----
+
+### Upload a file ###
+
+```php
+<?php
+use Icewind\SMB\Server;
+
+require('vendor/autoload.php');
+
+$fileToUpload = __FILE__;
+
+$server = new Server('localhost', 'test', 'test');
+$share = $server->getShare('test');
+$share->put($fileToUpload, 'example.txt');
+```
+
+### Download a file ###
+
+```php
+<?php
+use Icewind\SMB\Server;
+
+require('vendor/autoload.php');
+
+$target = __DIR__ . '/target.txt';
+
+$server = new Server('localhost', 'test', 'test');
+$share = $server->getShare('test');
+$share->get('example.txt', $target);
+```
+
+### List shares on the remote server ###
+
+```php
+<?php
+use Icewind\SMB\Server;
+
+require('vendor/autoload.php');
+
+$server = new Server('localhost', 'test', 'test');
+$shares = $server->listShares();
+
+foreach ($shares as $share) {
+	echo $share->getName() . "\n";
+}
+```
+
+### List the content of a folder ###
+
+```php
+<?php
+use Icewind\SMB\Server;
+
+require('vendor/autoload.php');
+
+$server = new Server('localhost', 'test', 'test');
+$share = $server->getShare('test');
+$content = $share->dir('test');
+
+foreach ($content as $info) {
+	echo $name->getName() . "\n";
+	echo "\tsize :" . $info->getSize() . "\n";
+}
+```
+
+### Using read streams
+
+```php
+<?php
+use Icewind\SMB\Server;
+
+require('vendor/autoload.php');
+
+$server = new Server('localhost', 'test', 'test');
+$share = $server->getShare('test');
+
+$fh = $share->read('test.txt');
+echo fread($fh, 4086);
+fclose($fh);
+```
+
+### Using write streams
+
+```php
+<?php
+use Icewind\SMB\Server;
+
+require('vendor/autoload.php');
+
+$server = new Server('localhost', 'test', 'test');
+$share = $server->getShare('test');
+
+$fh = $share->write('test.txt');
+fwrite($fh, 'bar');
+fclose($fh);
+```
+
+### Using libsmbclient-php ###
+
+Install [libsmbclient-php](https://github.com/eduardok/libsmbclient-php)
+
+```php
+<?php
+use Icewind\SMB\Server;
+use Icewind\SMB\NativeServer;
+
+require('vendor/autoload.php');
+
+$fileToUpload = __FILE__;
+
+if (Server::NativeAvailable()) {
+    $server = new NativeServer('localhost', 'test', 'test');
+} else {
+    echo 'libsmbclient-php not available, falling back to wrapping smbclient';
+    $server = new Server('localhost', 'test', 'test');
+}
+$share = $server->getShare('test');

+Generic stream wrappers for php.
+
+##CallBackWrapper##
+
+A `CallBackWrapper` can be used to register callbacks on read, write and closing of the stream,
+it wraps an existing stream and can thus be used for any stream in php
+
+The callbacks are passed in the stream context along with the source stream
+and can be any valid [php callable](http://php.net/manual/en/language.types.callable.php)
+
+###Example###
+```php
+<?php
+
+use \Icewind\Streams\CallBackWrapper;
+
+require('vendor/autoload.php');
+
+// get an existing stream to wrap
+$source = fopen('php://temp', 'r+');
+
+// register the callbacks
+$stream = CallbackWrapper::wrap($source,
+	// read callback
+	function ($count) {
+		echo "read " . $count . "bytes\n";
+	},
+	// write callback
+	function ($data) {
+		echo "wrote '" . $data . "'\n";
+	},
+	// close callback
+	function () {
+		echo "stream closed\n";
+	});
+
+fwrite($stream, 'some dummy data');
+
+rewind($stream);
+fread($stream, 5);
+
+fclose($stream);
+```
+
+Note: due to php's internal stream buffering the `$count` passed to the read callback
+will be equal to php's internal buffer size (8192 on default) an not the number of bytes
+requested by `fopen()`
