How does this work with non-Chrome embedders?

[Primiano Tucci (use gerrit), 2016/06/24 12:39:43]

version_info is not a chrome thingy. It's a component.

   metadata_dict->SetString("user-agent", GetContentClient()->GetUserAgent());
 
   // OS
   metadata_dict->SetString("os-name", base::SysInfo::OperatingSystemName());
   metadata_dict->SetString("os-version",

   metadata_dict->SetString("os-arch",
                            base::SysInfo::OperatingSystemArchitecture());
 
   // CPU
