Installing Scripts

I would like to install the UV Toolkit. It says to just add this to Blenders default script folder. I do not see the new tools installed in Blender. Does this means the script is outdated? Or am I missing a part to installing scripts?

You don’t give a link to the script or indicate the version of blender you are currently using.
If the script was written for blender 2.4x and you are using blender 2.6x then it will not work.
