"The central class in the :mod:`email` package is the :class:`EmailMessage` "
"class, imported from the :mod:`email.message` module.  It is the base class "
"for the :mod:`email` object model.  :class:`EmailMessage` provides the core "
"functionality for setting and querying header fields, for accessing message "
"bodies, and for creating or modifying structured messages."
msgstr ""

"An email message consists of *headers* and a *payload* (which is also "
"referred to as the *content*).  Headers are :rfc:`5322` or :rfc:`6532` style "
"field names and values, where the field name and value are separated by a "
"colon.  The colon is not part of either the field name or the field value.  "
"The payload may be a simple text message, or a binary object, or a "
"structured sequence of sub-messages each with their own set of headers and "
"their own payload.  The latter type of payload is indicated by the message "
"having a MIME type such as :mimetype:`multipart/\\*` or :mimetype:`message/"
"rfc822`."

"The conceptual model provided by an :class:`EmailMessage` object is that of "
"an ordered dictionary of headers coupled with a *payload* that represents "
"the :rfc:`5322` body of the message, which might be a list of sub-"
"``EmailMessage`` objects.  In addition to the normal dictionary methods for "
"accessing the header names and values, there are methods for accessing "
"specialized information from the headers (for example the MIME content "
"type), for operating on the payload, for generating a serialized version of "
"the message, and for recursively walking over the object tree."

"The :class:`EmailMessage` dictionary-like interface is indexed by the header "
"names, which must be ASCII values.  The values of the dictionary are strings "
