original_docstring: Open a file, downloading it first if it does not yet exist.
  
          Unlike when you call a loader directly like ``my_loader()``,
          this ``my_loader.open()`` method does not attempt to parse or
          interpret the file; it simply returns an open file object.
  
          The ``url`` can be either an external URL, or else the path to a
          file on the current filesystem.  A relative path will be assumed
          to be relative to the base directory of this loader object.
  
          If a URL was provided and the ``reload`` parameter is true, then
          any existing file will be removed before the download starts.
  
          The ``filename`` parameter lets you specify an alternative local
          filename instead of having the filename extracted from the final
          component of the URL.
