erb is yet another eRuby implementation. It is written by Pure Ruby.
erb has two classes, ERb and ERbLight. ERbLight is simple and lightweight.
It is easily combined with your application.


== simple usage

  erb = ERbLight.new(eruby_script)
  erb.run                   # eval, and write to stdout
  str = erb.result          # eval with toplevel_binding, return page as String
  str = erb.result(binding) # eval with binding


== scope, exception

  class Page
    @@erb = ERbLight.new(template)
    @@err = ERbLight.new(error_template)
    ...
    def to_html
      @@erb.result(binding) # eval with instance scope
    rescue
      @@err.result(binding)
    end
    ...
  end
