You can probably combine this and the one below into one.  Just pass in
src/tools/nodejs/linux/*.sha1
as the pattern, 
src/tools/nodejs/linux
as the target, and add an extra --directory flag, and omit the -s flag.

I'm not 100% clear on what you mean :) Could you please give an example of what
it would look like?

Is it better to just keep them separate as-is for clarity?

[Ryan Tseng, 2014/01/07 23:00:45]

So this would be

{
  "name":  "nodejs_linux",
  "pattern": "src/tools/nodejs/linux/*.sha1",
  "action": [ "download_from_google_storage',
                 "--no_resume",
                 "--platform=linux*",
                 "--no_auth",
                 "--bucket", "chromium-nodejs",
                 "--directory", "src/tools/nodejs/linux",]
}

I think It makes sense to put them together since they always get triggered
together.  Also that results in less hooks.
