+Twitter for PHP (c) David Grudl, 2008 (http://davidgrudl.com)
+
+
+Introduction
+------------
+
+Twitter for PHP is a very small and easy-to-use library for sending 
+messages to Twitter and receiving status updates.
+
+
+Project at GoogleCode: http://twitter-php.googlecode.com
+Twitter's API documentation: http://groups.google.com/group/twitter-development-talk/web/api-documentation
+My PHP blog: http://phpfashion.com
+
+
+Requirements
+------------
+- PHP (version 5 or better)
+- cURL extension
+
+
+Usage
+-----
+
+Create object using your credentials (user name and password)
+
+	$twitter = new Twitter($userName, $password);
+
+The send() method updates your status. The message must be encoded in UTF-8:
+
+	$twitter->send('I am fine today.');
+
+The load() method returns the 20 most recent status updates 
+posted in the last 24 hours by you and optionally by your friends:
+
+	$withFriends = FALSE;
+	$channel = $twitter->load($withFriends);
+
+The returned channel is a SimpleXMLElement object. Extracting 
+the information from the channel is easy:
+
+	foreach ($channel->status as $status) {
+		echo "message: ", $status->text;
+		echo "posted at " , $status->created_at;
+		echo "posted by " , $status->user->name;
+	}
+
