[Lei Zhang, 2014/05/12 21:45:37]

Is this intention or for local testing?

[Sam Clegg, 2014/05/12 22:25:32]

I can revert this for now, but I really wanted a directory that
would persist between runs.  I can do that in a different change.
Maybe just use chrome's 'out' folder?

[Lei Zhang, 2014/05/12 22:34:17]

It does mean a lot less downloads. I've done it for testing purposes locally.
