How does Rails 3 actionmailer decide which format to use?

In documentation it says, that mailer actions behave in very similar fashion as controller actions. In rails guide, to send mail:

UserMailer.welcome_email(@user).deliver

and welcome_email action looks like this:

def welcome_email(user)
  @user = user
  @url = "http://example.com/login"
  mail(:to => user.email, :subject => "Welcome to My Awesome Site") do |format|
   format.html { render 'another_template' }
   format.text { render 'another_template' }
  end 
end

what I don't get is, how welcome_email action decides which format to use (html or text)?

Thanks!

I believe it will create a multipart email that includes both html and text parts. This will allow text only clients to render it using that part and html based clients to render it properly too.
