I have a project drawing floor plan to do at school, and I used AppleWorks, which is not available in newer Macs. Which program do we open with the AppleWorks file ?

For my Macbook, Snow Leopard, I installed "Rosetta". It was on the Software CD that came with the mac. The message came up telling me what I needed when I tried installing Appleworks. So, I searched for it on the CD. If it had'nt been on there I would have gone on line looking for it on the support page.
