 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
