Thanks for this Lorna!

I played around with a couple different strategies, and I settled on doing the following:
Create "prev" and "next" directories that both contain code, with "www" being a symlink which Apache points to as the DocumentRoot

- Use the "next" folder:
[code]ln -fns next www[/code]

- Use the "prev" folder:
[code]ln -fns prev www[/code]

Works pretty well - thanks for the catalyst :)
