// Open is a high-level wrapper that takes a variadic number of URLs, opens or
// creates each of the specified resources, and combines them into a locked
// WriteSyncer. It also returns any error encountered and a function to close
// any opened files.
//
// Passing no URLs returns a no-op WriteSyncer. Zap handles URLs without a
// scheme and URLs with the "file" scheme. Third-party code may register
// factories for other schemes using RegisterSink.
//
// URLs with the "file" scheme must use absolute paths on the local
// filesystem. No user, password, port, fragments, or query parameters are
// allowed, and the hostname must be empty or "localhost".
//
// Since it's common to write logs to the local filesystem, URLs without a
// scheme (e.g., "/var/log/foo.log") are treated as local file paths. Without
// a scheme, the special paths "stdout" and "stderr" are interpreted as
// os.Stdout and os.Stderr. When specified without a scheme, relative file
// paths also work.
