NAME
       Mail::SpamAssassin::Message::Node - decode, render, and make available
       MIME message parts
DESCRIPTION
       This module will encapsulate an email message and allow access to the
       various MIME message parts.
PUBLIC METHODS
       new()
           Generates an empty Node object and returns it.  Typically only
           called by functions in Message.
       find_parts()
           Used to search the tree for specific MIME parts.  An array of
           matching Node objects (pointers into the tree) is returned.  The
           parameters that can be passed in are (in order, all scalars):
           Regexp - Used to match against each part's Content-Type header,
           specifically the type and not the rest of the header.  ie:
           "Content-type: text/html; encoding=quoted-printable" has a type of
           "text/html".  If no regexp is specified, find_parts() will return
           an empty array.
           Only_leaves - By default, find_parts() will return any part that
           matches the regexp, including multipart.  If you only want to see
           leaves of the tree (ie: parts that aren't multipart), set this to
           true (1).
           Recursive - By default, when find_parts() finds a multipart which
           has parts underneath it, it will recurse through all sub-children.
           If set to 0, only look at the part and any direct children of the
           part.
       header()
           Stores and retrieves headers from a specific MIME part.  The first
           parameter is the header name.  If there is no other parameter, the
           header is retrieved.  If there is a second parameter, the header is
           stored.
           Header names are case-insensitive and are stored in both raw and
           decoded form.  Using header(), only the decoded form is
           retrievable.
           For retrieval, if header() is called in an array context, an array
           will be returned with each header entry in a different element.  In
           a scalar context, the last specific header is returned.
           ie: If 'Subject' is specified as the header, and there are 2
           Subject headers in a message, the last/bottom one in the message is
           returned in scalar context or both are returned in array context.
       raw_header()
           Retrieves the raw version of headers from a specific MIME part.
           The only parameter is the header name.  Header names are case-
           insensitive.
           For retrieval, if raw_header() is called in an array context, an
           array will be returned with each header entry in a different
           element.  In a scalar context, the last specific header is
           returned.
           ie: If 'Subject' is specified as the header, and there are 2
           Subject headers in a message, the last/bottom one in the message is
           returned in scalar context or both are returned in array context.
       add_body_part()
           Adds a Node child object to the current node object.
       is_leaf()
           Returns true if the tree node in question is a leaf of the tree
           (ie: has no children of its own).  Note: This function may return
           odd results unless the message has been mime parsed via
           _do_parse()!
       raw()
           Return a reference to the raw array.  Treat this as READ ONLY.
       decode()
           If necessary, decode the part text as base64 or quoted-printable.
           The decoded text will be returned as a scalar string.  An optional
           length parameter can be passed in which limits how much decoded
           data is returned.  If the scalar isn't needed, call with "0" as a
           parameter.
       rendered()
           render_text() takes the given text/* type MIME part, and attempts
           to render it into a text scalar.  It will always render text/html,
           and will use a heuristic to determine if other text/* parts should
           be considered text/html.  Two scalars are returned: the rendered
           type (either text/html or whatever the original type was), and the
           rendered text.
       set_rendered($text, $type)
           Set the rendered text and type for the given part.  If type is not
           specified, and text is a defined value, a default of 'text/plain'
           is used.  This can be used, for instance, to render non-text parts
           using plugins.
       visible_rendered()
           Render and return the visible text in this part.
       invisible_rendered()
           Render and return the invisible text in this part.
       content_summary()
           Returns an array of scalars describing the mime parts of the
           message.  Note: This function requires that the message be parsed
           first!
       delete_header()
           Delete the specified header (decoded and raw) from the Node
           information.
       get_header()
           Retrieve a specific header.  Will have a newline at the end and
           will be unfolded.  The first parameter is the header name (case-
           insensitive), and the second parameter (optional) is whether or not
           to return the raw header.
           If get_header() is called in an array context, an array will be
           returned with each header entry in a different element.  In a
           scalar context, the last specific header is returned.
           ie: If 'Subject' is specified as the header, and there are 2
           Subject headers in a message, the last/bottom one in the message is
           returned in scalar context or both are returned in array context.
           Btw, returning the last header field (not the first) happens to be
           consistent with DKIM signatures, which search for and cover
           multiple header fields bottom-up according to the 'h' tag. Let's
           keep it this way.
       get_all_headers()
           Retrieve all headers.  Each header will have a newline at the end
           and will be unfolded.  The first parameter (optional) is whether or
           not to return the raw headers, and the second parameter (optional)
           is whether or not to include the mbox separator.
           If get_all_header() is called in an array context, an array will be
           returned with each header entry in a different element.  In a
           scalar context, the headers are returned in a single scalar.
