The :class:`Parser` class, imported from the :mod:`email.parser` module,
provides an API that can be used to parse a message when the complete contents
of the message are available in a string or file. The :mod:`email.parser`
-module also provides a second class, called :class:`HeaderParser` which can be
-used if you're only interested in the headers of the message.
-:class:`HeaderParser` can be much faster in these situations, since it does not
-attempt to parse the message body, instead setting the payload to the raw body
-as a string. :class:`HeaderParser` has the same API as the :class:`Parser`
-class.
+module also provides header-only parsers, called :class:`HeaderParser` and
+:class:`BytesHeaderParser`, which can be used if you're only interested in the
+headers of the message. :class:`HeaderParser` and :class:`BytesHeaderParser`

+message body, instead setting the payload to the raw body as a string. They
