UV Toolkit Installation

Hi, I’m fairly new to blender. I would like to install the UV toolkit http://wiki.blender.org/index.php/Extensions:2.4/Py/Scripts/Toolkits/UV_Menu

Anyways I put the folders in the Script section as stated, and nothing. I haven’t installed any scripts for Blender before. Is this outdated or does it still work well?

This is a Blender 2.49 script. And might not work in Blender 2.5 and higher.
