class_docstr: PEP 302 Finder that wraps Python's "classic" import algorithm
  
  ImpImporter(dirname) produces a PEP 302 finder that searches that
  directory.  ImpImporter(None) produces a PEP 302 finder that searches
  the current sys.path, plus any modules that are frozen or built-in.
  
  Note that ImpImporter does not currently support being used by placement
  on sys.meta_path.
