 *Rails 3.0 (pending)*
 
+* Whole new API added with tests.  See base.rb for full details.  Old API is deprecated.
+
 * The Mail::Message class has helped methods for all the field types that return 'common' defaults for the common use case, so to get the subject, mail.subject will give you a string, mail.date will give you a DateTime object, mail.from will give you an array of address specs (mikel@test.lindsaar.net) etc.  If you want to access the field object itself, call mail[:field_name] which will return the field object you want, which you can then chain, like mail[:from].formatted
 
 * Mail#content_type now returns the content_type field as a string. If you want the mime type of a mail, then you call Mail#mime_type (eg, text/plain), if you want the parameters of the content type field, you call Mail#content_type_parameters which gives you a hash, eg {'format' => 'flowed', 'charset' => 'utf-8'}

+Action Mailer is in essence a wrapper around Action Controller and the 
+Mail gem.  It provides a way to make emails using templates in the same
+way that Action Controller renders views using templates.
+
 Additionally, an Action Mailer class can be used to process incoming email,
 such as allowing a weblog to accept new posts from an email (which could even
 have been sent from a phone).
 
 == Sending emails
 
-The framework works by setting up all the email details, except the body,
-in methods on the service layer. Subject, recipients, sender, and timestamp
-are all set up this way. An example of such a method:
+The framework works by initializing any instance variables you want to be
+available in the email template, followed by a call to +mail+ to deliver
+the email.
+
+This can be as simple as:
 
-  def signed_up(recipient)
-    recipients recipient
-    subject    "[Signed up] Welcome #{recipient}"
-    from       "system@loudthinking.com"
-    body       :recipient => recipient
+  class Notifier < ActionMailer::Base
+    delivers_from 'system@loudthinking.com'
+  
+    def welcome(recipient)
+      @recipient = recipient
+      mail(:to => recipient,
+           :subject => "[Signed up] Welcome #{recipient}")
+    end
   end
 
 The body of the email is created by using an Action View template (regular
-ERb) that has the content of the body hash parameter available as instance variables. 
+ERb) that has the instance variables that are declared in the mailer action.
+
 So the corresponding body template for the method above could look like this:
 
   Hello there, 
 
   Mr. <%= @recipient %>
+
+  Thank you for signing up!
   
 And if the recipient was given as "david@loudthinking.com", the email 
 generated would look like this:
 
-  Date: Sun, 12 Dec 2004 00:00:00 +0100
+  Date: Mon, 25 Jan 2010 22:48:09 +1100
   From: system@loudthinking.com
   To: david@loudthinking.com
+  Message-ID: <4b5d84f9dd6a5_7380800b81ac29578@void.loudthinking.com.mail>
   Subject: [Signed up] Welcome david@loudthinking.com
+  Mime-Version: 1.0
+  Content-Type: text/plain;
+  	charset="US-ASCII";
+  Content-Transfer-Encoding: 7bit
 
   Hello there, 
 
   Mr. david@loudthinking.com
 
-You never actually call the instance methods like signed_up directly. Instead,
-you call class methods like deliver_* and create_* that are automatically
-created for each instance method. So if the signed_up method sat on
-ApplicationMailer, it would look like this:
+In previous version of rails you would call <tt>create_method_name</tt> and
+<tt>deliver_method_name</tt>.  Rails 3.0 has a much simpler interface, you
+simply call the method and optionally call +deliver+ on the return value.
 
-  ApplicationMailer.create_signed_up("david@loudthinking.com")  # => tmail object for testing
-  ApplicationMailer.deliver_signed_up("david@loudthinking.com") # sends the email
-  ApplicationMailer.new.signed_up("david@loudthinking.com")     # won't work!
+Calling the method returns a Mail Message object:
+
+  message = Notifier.welcome  #=> Returns a Mail::Message object
+  message.deliver             #=> delivers the email
+
+Or you can just chain the methods together like:
+
+  Notifier.welcome.deliver    # Creates the email and sends it immediately

+    #   <tt>[:actionmailer, mailer_scope, action_name]</tt> or if this is missing, will translate the
+    #   humanized version of the <tt>action_name</tt>
+    # * <tt>:to</tt> - Who the message is destined for, can be a string of addresses, or an array
+    #   of addresses.
+    # * <tt>:from</tt> - Who the message is from, if missing, will use the <tt>:delivers_from</tt>
+    #   value in the class (if it exists)
+    # * <tt>:cc</tt> - Who you would like to Carbon-Copy on this email, can be a string of addresses,
+    #   or an array of addresses.
+    # * <tt>:bcc</tt> - Who you would like to Blind-Carbon-Copy on this email, can be a string of
+    #   addresses, or an array of addresses.
+    # * <tt>:reply_to</tt> - Who to set the Reply-To header of the email to.
+    # * <tt>:date</tt> - The date to say the email was sent on.
+    # 
+    # If you need other headers not listed above, use the <tt>headers['name'] = value</tt> method.
+    #
+    # When a <tt>:return_path</tt> is specified as header, that value will be used as the 'envelope from'
+    # address for the Mail message.  Setting this is useful when you want delivery notifications
+    # sent to a different address than the one in <tt>:from</tt>.  Mail will actually use the 
+    # <tt>:return_path</tt> in preference to the <tt>:sender</tt> in preference to the <tt>:from</tt>
+    # field for the 'envelope from' value.
+    #
+    # If you do not pass a block to the +mail+ method, it will find all templates in the 
+    # template path that match the method name that it is being called from, it will then
+    # create parts for each of these templates intelligently, making educated guesses
+    # on correct content type and sequence, and return a fully prepared Mail::Message
+    # ready to call <tt>:deliver</tt> on to send.
+    #
+    # If you do pass a block, you can render specific templates of your choice:
+    # 
+    #   mail(:to => 'mikel@test.lindsaar.net') do |format|
+    #     format.text
+    #     format.html
+    #   end
+    # 
+    # You can even render text directly without using a template:
+    # 
+    #   mail(:to => 'mikel@test.lindsaar.net') do |format|

+    # Which will render a <tt>multipart/alternative</tt> email with <tt>text/plain</tt> and
+    # <tt>text/html</tt> parts.
