Chris may know the best way to do this

[cjhopman, 2013/04/25 01:02:06]

Haven't looked at the rest of the change yet, but for this:

Much better than calling this in a subprocess would be to import
mirror_resources and call things directly.

I think I would prefer that this be done as a separate gyp action, though. Feel
free to ping me for details of what that would take.

[Kibeom Kim (inactive), 2013/04/25 01:49:35]

OK I'll try to make this a separate gyp action after converting this script to
handle layout-v17
