class Closure

  # Although Closure Script can run as an app or in a cascade, most installations
  # will use this {Middleware} configured with Closure.add_source().
  # @example config.ru
  #  require 'closure'
  #  Closure.add_source '../src/myapp', '/myapp'
  #  use Closure::Middleware
  
  class Middleware
    
    # @param (String) home_page File to serve at the root.  Handy for stand-alone projects.
    #   You can use a Closure Script, even in non-source folders, by using the url extension
    #   e.g. 'index.html' instead of the actual filename 'index.haml'.
    def initialize(app, home_page=nil)
      @app = app
      @server = ShowExceptions.new(Server.new(Closure.sources, home_page))
