+"""Exception classes raised by urllib.
+
+The base exception class is URLError, which inherits from OSError.  It
+doesn't define any behavior of its own, but is the base class for all
+exceptions defined in this package.
+
+HTTPError is an exception class that is also a valid HTTP response
+instance.  It behaves this way because HTTP protocol errors are valid
+responses, with a status code, headers, and a body.  In some contexts,
+an application may want to handle an exception like a regular
+response.
