= ContentFor
Small extension for the Sinatra[http://sinatrarb.com] web framework
that allows you to use the following helpers in your views:
<% content_for :some_key do %>
<chunk of="html">...</chunk>
<% end %>
<% yield_content :some_key %>
This allows you to capture blocks inside views to be rendered later
in this request. For example, to populate different parts of your
layout from your view.
== Usage
If you're writing "classic" style apps, then requring
<tt>sinatra/content_for</tt> should be enough. If you're writing
"classy" apps, then you also need to call
<tt>helpers Sinatra::ContentFor</tt> in your app definition.
== And how is this useful?
For example, some of your views might need a few javascript tags and
stylesheets, but you don't want to force this files in all your pages.
Then you can put <tt><% yield_content :scripts_and_styles %></tt> on
your layout, inside the <head> tag, and each view can call
<tt>content_for</tt> setting the appropriate set of tags that should
be added to the layout.
== Warning
This only works with ERB as a rendering mechanism. I haven't figured
how to make it work with Haml. If you find a way, contact me and I'll
include it.

Code by foca[http://github.com/foca], inspired on the Ruby on Rails
helpers with the same name.
