NAME
       Mail::SpamAssassin::Message::Metadata - extract metadata from a message

SYNOPSIS
DESCRIPTION
       This class is tasked with extracting "metadata" from messages for use as Bayes tokens, fodder for eval tests, or other rules.  Metadata is
       supplemental data inferred from the message, like the examples below.

       It is held in two forms:

       1. as name-value pairs of strings, presented in mail header format.  For
	 example, "X-Language" => "en".  This is the general form for simple
	 metadata that's useful as Bayes tokens, can be added to marked-up
	 messages using "add_header", etc., such as the trusted-relay inference
	 and language detection.

       2. as more complex data structures on the $msg->{metadata} object.  This
	 is the form used for metadata like the HTML parse data, which is stored
	 there for access by eval rule code.   Because it's not simple strings,
	 it's not added as a Bayes token by default (Bayes needs simple strings).
