def build(dst_path)

  writelines dst_path, lines
end

#localized_strings? ⇒ Boolean

Returns true if the current entry is a localized strings file. These files receive some specialized processing to allow for server-side only strings. – You can name a string key beginning with “@@” and it will be removed.
