MP3_playlist 0.5.1alpha1

Dear Team.

I aplogise if this is directed to the wrong person/s and if that is the case would someone please pass it along for me..

I downloaded this file as it is exactly what I am needing to make xml playlists form my mp3player om my pfp forum. My difficulty lies in my being a beginner with very little experience in php. I don't seem to be able to open this downloaded file in order to install anything. How does one open a Tar file? What utilities do I need in order to do so. I would greatly appreciate any helpful information you could give me..

Thank you in anticipation. Sincerely. Don Ellerton.
