this url could be shared with other file?

[justincohen, 2016/03/03 18:58:33]

Holding off on this change now to determine what else needs can be shared

shouldn't we control the extension? why not standardize on zip or gzip?

I removed the GYP_DEFINE check, that needs to be re-added.

As does an IsGoogler check.

[erikchen, 2016/03/03 01:45:47]

as does checking if xcode already exists (or whatever we're doing to no-op on
dev machines)

[justincohen, 2016/03/03 18:58:33]

added.

re-added.

This is wrong, as I still want to run xcode-select if the SDK is already up to
date.

Done.
