+:mod:`email`: Creating email and MIME objects from scratch
+----------------------------------------------------------
+
+.. module:: email.mime
+   :synopsis: Build MIME messages. 
+
+
+Ordinarily, you get a message object structure by passing a file or some text to
+a parser, which parses the text and returns the root message object.  However
+you can also build a complete message structure from scratch, or even individual
+:class:`Message` objects by hand.  In fact, you can also take an existing
+structure and add new :class:`Message` objects, move them around, etc.  This
+makes a very convenient interface for slicing-and-dicing MIME messages.
+
+You can create a new object structure by creating :class:`Message` instances,
+adding attachments and all the appropriate headers manually.  For MIME messages
+though, the :mod:`email` package provides some convenient subclasses to make
+things easier.
+
+Here are the classes:
+
+
+.. class:: MIMEBase(_maintype, _subtype, **_params)
+
+   Module: :mod:`email.mime.base`
+
+   This is the base class for all the MIME-specific subclasses of :class:`Message`.
+   Ordinarily you won't create instances specifically of :class:`MIMEBase`,
+   although you could.  :class:`MIMEBase` is provided primarily as a convenient
+   base class for more specific MIME-aware subclasses.
+
+   *_maintype* is the :mailheader:`Content-Type` major type (e.g. :mimetype:`text`
+   or :mimetype:`image`), and *_subtype* is the :mailheader:`Content-Type` minor
+   type  (e.g. :mimetype:`plain` or :mimetype:`gif`).  *_params* is a parameter
+   key/value dictionary and is passed directly to :meth:`Message.add_header`.
+
+   The :class:`MIMEBase` class always adds a :mailheader:`Content-Type` header
+   (based on *_maintype*, *_subtype*, and *_params*), and a
+   :mailheader:`MIME-Version` header (always set to ``1.0``).
+
+
+.. class:: MIMENonMultipart()
+
+   Module: :mod:`email.mime.nonmultipart`
+
+   A subclass of :class:`MIMEBase`, this is an intermediate base class for MIME
+   messages that are not :mimetype:`multipart`.  The primary purpose of this class
+   is to prevent the use of the :meth:`attach` method, which only makes sense for
+   :mimetype:`multipart` messages.  If :meth:`attach` is called, a
+   :exc:`MultipartConversionError` exception is raised.
+
+   .. versionadded:: 2.2.2
+
+
+.. class:: MIMEMultipart([subtype[, boundary[, _subparts[, _params]]]])
+
+   Module: :mod:`email.mime.multipart`
+
+   A subclass of :class:`MIMEBase`, this is an intermediate base class for MIME
+   messages that are :mimetype:`multipart`.  Optional *_subtype* defaults to
+   :mimetype:`mixed`, but can be used to specify the subtype of the message.  A
+   :mailheader:`Content-Type` header of :mimetype:`multipart/`*_subtype* will be
+   added to the message object.  A :mailheader:`MIME-Version` header will also be
+   added.
+
+   Optional *boundary* is the multipart boundary string.  When ``None`` (the
+   default), the boundary is calculated when needed.
+
+   *_subparts* is a sequence of initial subparts for the payload.  It must be
+   possible to convert this sequence to a list.  You can always attach new subparts
+   to the message by using the :meth:`Message.attach` method.
+
+   Additional parameters for the :mailheader:`Content-Type` header are taken from
+   the keyword arguments, or passed into the *_params* argument, which is a keyword
+   dictionary.
+
+   .. versionadded:: 2.2.2
+
+
+.. class:: MIMEApplication(_data[, _subtype[, _encoder[, **_params]]])
+
+   Module: :mod:`email.mime.application`
+
+   A subclass of :class:`MIMENonMultipart`, the :class:`MIMEApplication` class is
+   used to represent MIME message objects of major type :mimetype:`application`.
+   *_data* is a string containing the raw byte data.  Optional *_subtype* specifies
+   the MIME subtype and defaults to :mimetype:`octet-stream`.
+
+   Optional *_encoder* is a callable (i.e. function) which will perform the actual
+   encoding of the data for transport.  This callable takes one argument, which is
+   the :class:`MIMEApplication` instance. It should use :meth:`get_payload` and
+   :meth:`set_payload` to change the payload to encoded form.  It should also add
+   any :mailheader:`Content-Transfer-Encoding` or other headers to the message
+   object as necessary.  The default encoding is base64.  See the
+   :mod:`email.encoders` module for a list of the built-in encoders.
+
+   *_params* are passed straight through to the base class constructor.
+
+   .. versionadded:: 2.5
+
+
+.. class:: MIMEAudio(_audiodata[, _subtype[, _encoder[, **_params]]])
+
+   Module: :mod:`email.mime.audio`
+
+   A subclass of :class:`MIMENonMultipart`, the :class:`MIMEAudio` class is used to
+   create MIME message objects of major type :mimetype:`audio`. *_audiodata* is a
+   string containing the raw audio data.  If this data can be decoded by the
+   standard Python module :mod:`sndhdr`, then the subtype will be automatically
+   included in the :mailheader:`Content-Type` header.  Otherwise you can explicitly
+   specify the audio subtype via the *_subtype* parameter.  If the minor type could
+   not be guessed and *_subtype* was not given, then :exc:`TypeError` is raised.
+
+   Optional *_encoder* is a callable (i.e. function) which will perform the actual
+   encoding of the audio data for transport.  This callable takes one argument,
+   which is the :class:`MIMEAudio` instance. It should use :meth:`get_payload` and
+   :meth:`set_payload` to change the payload to encoded form.  It should also add
+   any :mailheader:`Content-Transfer-Encoding` or other headers to the message
+   object as necessary.  The default encoding is base64.  See the
+   :mod:`email.encoders` module for a list of the built-in encoders.
+
+   *_params* are passed straight through to the base class constructor.
+
+
+.. class:: MIMEImage(_imagedata[, _subtype[, _encoder[, **_params]]])
+
+   Module: :mod:`email.mime.image`
+
+   A subclass of :class:`MIMENonMultipart`, the :class:`MIMEImage` class is used to
+   create MIME message objects of major type :mimetype:`image`. *_imagedata* is a
+   string containing the raw image data.  If this data can be decoded by the
+   standard Python module :mod:`imghdr`, then the subtype will be automatically
+   included in the :mailheader:`Content-Type` header.  Otherwise you can explicitly
+   specify the image subtype via the *_subtype* parameter.  If the minor type could
+   not be guessed and *_subtype* was not given, then :exc:`TypeError` is raised.
+
+   Optional *_encoder* is a callable (i.e. function) which will perform the actual
+   encoding of the image data for transport.  This callable takes one argument,
+   which is the :class:`MIMEImage` instance. It should use :meth:`get_payload` and
+   :meth:`set_payload` to change the payload to encoded form.  It should also add
+   any :mailheader:`Content-Transfer-Encoding` or other headers to the message
+   object as necessary.  The default encoding is base64.  See the
+   :mod:`email.encoders` module for a list of the built-in encoders.
+
+   *_params* are passed straight through to the :class:`MIMEBase` constructor.
+
+
+.. class:: MIMEMessage(_msg[, _subtype])
+
+   Module: :mod:`email.mime.message`
+
+   A subclass of :class:`MIMENonMultipart`, the :class:`MIMEMessage` class is used
+   to create MIME objects of main type :mimetype:`message`. *_msg* is used as the
+   payload, and must be an instance of class :class:`Message` (or a subclass
+   thereof), otherwise a :exc:`TypeError` is raised.
+
+   Optional *_subtype* sets the subtype of the message; it defaults to
+   :mimetype:`rfc822`.
+
+
+.. class:: MIMEText(_text[, _subtype[, _charset]])
+
+   Module: :mod:`email.mime.text`
+
+   A subclass of :class:`MIMENonMultipart`, the :class:`MIMEText` class is used to
+   create MIME objects of major type :mimetype:`text`. *_text* is the string for
+   the payload.  *_subtype* is the minor type and defaults to :mimetype:`plain`.
+   *_charset* is the character set of the text and is passed as a parameter to the
+   :class:`MIMENonMultipart` constructor; it defaults to ``us-ascii``.  No guessing
+   or encoding is performed on the text data.
+
+   .. versionchanged:: 2.4
+      The previously deprecated *_encoding* argument has been removed.  Encoding
+      happens implicitly based on the *_charset* argument.
