problem.

 This module defines a standard interface to break URL strings up in
-components (addessing scheme, network location, path etc.), to combine
+components (addressing scheme, network location, path etc.), to combine
 the components back into a URL string, and to convert a ``relative
 URL'' to an absolute URL given a ``base URL.''
