Ther RTLer

Remember the WordPress plugin:The RTLer? Well its author l0uy re-released yesterday the tool as a standalone web service so you can RTL any CSS you need.
But remember, it gives you an overridden RTLed CSS you include in addition to the LTR version, like below:

<!-- Your LTR CSS here -->
<link rel="stylesheet" type="text/css" href="style.css" media="all" />
<!-- The generated RTLed CSS here -->
<link rel="stylesheet" type="text/css" href="rtl.css" media="all" />
