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'.
