So is there no way to now specify if you want to download the results zip from
Appurify? That still seems like it could be useful for devs running it, and not
having to know how to deal with appurify's website.

[jbudorick, 2015/10/26 22:23:30]

Agreed. I don't think this should be deprecated.

[mikecase (-- gone --), 2015/10/27 01:27:43]

Well, now when you shard you are going to get num_shard zips. I guess I could
add the option to copy all of the result_zip files into a folder. Yeah, I'll do
that I suppose. I guess its still could be usable to devs if they set
--num_shards 1 and then they would get 1 zip with all of the results.

Done.

Now passing --results-dir /my/temp/dir
will put a bunch of results-<random tempfile string>.zip files into the
directory
