module ActionMailer
# Accessors and helpers that ActionMailer::Base and ActionMailer::Part have
# in common. Using these helpers you can easily add subparts or attachments
# to your message:
#
# def my_mail_message(...)
# ...
# part "text/plain" do |p|
# p.body "hello, world"
# p.transfer_encoding "base64"
# end
#
# attachment "image/jpg" do |a|
# a.body = File.read("hello.jpg")
# a.filename = "hello.jpg"
# end
# end
module PartContainer

attr_reader :parts
# Add a part to a multipart message, with the given content-type. The
# part itself is yielded to the block so that other properties (charset,
# body, headers, etc.) can be set on it.
