uh-oh, I'm not sure if I trust Ross' judgement, though we have QA'ed it a bunch of times and it apparently works.
the only nitpick I have is that the indentation is inconsistent. I sent it originally as 4-space (since that's what I prefer), but part of this has been modified to have 2-space.
probably should be one or the other (4-space? ;-) )

Haven't tested locally. But looks fine.

Few points:
1. I like 4 spaces for tabs too, but let's prefer consistency (2 spaces)
2. Consider adding some test scripts in due course :)
