    # This is the mechanism for setting up your application layout.
    # There are three application layouts in Merb:
    #
    # 1. Regular app/:type layout of Ruby on Rails fame:
    #
    # app/models       for models
    # app/mailers      for mailers (special type of controllers)
    # app/parts        for parts, Merb components
    # app/views        for templates
    # app/controllers  for controller
    # lib              for libraries
    #
    # 2. Flat application layout:
    #
    # application.rb       for models, controllers, mailers, etc
    # config/init.rb       for initialization and router configuration
    # config/framework.rb  for framework and dependencies configuration
    # views                for views
    #
    # 3. Camping-style "very flat" application layout, where the whole Merb
    # application and configs are contained within a single file.
    #
    # ==== Notes
    # Autoloading for lib uses an empty glob by default. If you
    # want to have your libraries under lib use autoload, add
    # the following to Merb init file:
    #
    # Merb.push_path(:lib, Merb.root / "lib", "**/*.rb") # glob set explicity.
    #
    # Then lib/magicwand/lib/magicwand.rb with MagicWand module will
    # be autoloaded when you first access that constant.
    #
    # ==== Examples
    # This method gives you a way to build up your own application
    # structure, for instance, to reflect the structure Rails
    # uses to simplify transition of legacy application, you can
    # set it up like this:
    #
    # Merb.push_path(:model,      Merb.root / "app" / "models",      "**/*.rb")
    # Merb.push_path(:mailer,     Merb.root / "app" / "models",      "**/*.rb")
    # Merb.push_path(:controller, Merb.root / "app" / "controllers", "**/*.rb")
    # Merb.push_path(:view,       Merb.root / "app" / "views",       "**/*.rb")
    #
    # ==== Parameters
    # type<Symbol>:: The type of path being registered (i.e. :view)
    # path<String>:: The full path
    # file_glob<String>::
    #   A glob that will be used to autoload files under the path. Defaults to
    #   "**/*.rb".
    #
    # :api: public
    def push_path(type, path, file_glob = "**/*.rb")
      enforce!(type => Symbol)
      load_paths[type] = [path, file_glob]
    end

    # Removes given types of application components
    # from load path Merb uses for autoloading.
    #
    # ==== Parameters
    # *args<Array(Symbol)>::
    #   component(s) names, for instance, :views, :models
    #
    # ==== Examples
    # Using this combined with Merb::GlobalHelpers.push_path you can make 
    # your Merb application use legacy Rails application components.
    #
    # Merb.root = "path/to/legacy/app/root"
    # Merb.remove_paths(:mailer)
    # Merb.push_path(:mailer, Merb.root / "app" / "models", "**/*.rb")
    #
    # Will make Merb use app/models for mailers just like Ruby on Rails does.

    # :api: public

    # This is the mechanism for setting up your application layout.
    # There are three application layouts in Merb:
    #
    # 1. Regular app/:type layout of Ruby on Rails fame:
    #
    # app/models       for models
    # app/mailers      for mailers (special type of controllers)
    # app/parts        for parts, Merb components
    # app/views        for templates
    # app/controllers  for controller
    # lib              for libraries
    #
    # 2. Flat application layout:
    #
    # application.rb       for models, controllers, mailers, etc
    # config/init.rb       for initialization and router configuration
    # config/framework.rb  for framework and dependencies configuration
    # views                for views
    #
    # 3. Camping-style "very flat" application layout, where the whole Merb
    # application and configs are contained within a single file.
    #
    # ==== Notes
    # Autoloading for lib uses an empty glob by default. If you
    # want to have your libraries under lib use autoload, add
    # the following to Merb init file:
    #
    # Merb.push_path(:lib, Merb.root / "lib", "**/*.rb") # glob set explicity.
    #
    # Then lib/magicwand/lib/magicwand.rb with MagicWand module will
    # be autoloaded when you first access that constant.
    #
    # ==== Examples
    # This method gives you a way to build up your own application
    # structure, for instance, to reflect the structure Rails
    # uses to simplify transition of legacy application, you can
    # set it up like this:
    #
    # Merb.push_path(:model,      Merb.root / "app" / "models",      "**/*.rb")
    # Merb.push_path(:mailer,     Merb.root / "app" / "models",      "**/*.rb")
    # Merb.push_path(:controller, Merb.root / "app" / "controllers", "**/*.rb")
    # Merb.push_path(:view,       Merb.root / "app" / "views",       "**/*.rb")
    #
    # ==== Parameters
    # type<Symbol>:: The type of path being registered (i.e. :view)
    # path<String>:: The full path
    # file_glob<String>::
    #   A glob that will be used to autoload files under the path. Defaults to
    #   "**/*.rb".
    #
    # :api: public

    # from load path Merb uses for autoloading.
    #
    # ==== Parameters
    # *args<Array(Symbol)>::
    #   component(s) names, for instance, :views, :models
    #
    # ==== Examples
    # Using this combined with Merb::GlobalHelpers.push_path you can make 
    # your Merb application use legacy Rails application components.
    #
    # Merb.root = "path/to/legacy/app/root"
    # Merb.remove_paths(:mailer)
    # Merb.push_path(:mailer, Merb.root / "app" / "models", "**/*.rb")
    #
    # Will make Merb use app/models for mailers just like Ruby on Rails does.
