  /tmp > cat amrita.rb
  require 'amrita/template'
  include Amrita

  TEMPLATE = <<-html
    <a id="main_elt">
      <img id="thumb_pic">
      <div class="title" id="title"></div>
    </a>
  html

  model = Hash[
    :main_elt => a(:href => 'http://www.google.com') do
      Hash[
	:thumb_pic => a(:src => 'image.png'),
	:title => 'name',
      ]
    end
  ]

  (TemplateText.new TEMPLATE).expand STDOUT, model

  /tmp > ruby amrita.rb
  <a href="http://www.google.com">
    <img src="image.png">
    <div class="title">name</div>
  </a>


Amrita::a() can take a block.  if a the calling the block returns a string that
string is used to replace body of the tag wholesale, if the block returns a
hash, it is used to fill in any nested template - like you have.

you could also write the model as:

    model = { # a hash
      :main_elt => a(:href => 'http://www.google.com') { # a block
	# the block returns a hash
	{:thumb_pic => a(:src => 'image.png'), :title => 'name'}
      }
    }

-a
