23: * App is responsible for path management, class location and class loading.
24: *
25: * ### Adding paths
26: *
27: * You can add paths to the search indexes App uses to find classes using `App::build()`. Adding
28: * additional controller paths for example would alter where CakePHP looks for controllers.
29: * This allows you to split your application up across the filesystem.
30: *
31: * ### Packages
32: *
33: * CakePHP is organized around the idea of packages, each class belongs to a package or folder where other
34: * classes reside. You can configure each package location in your application using `App::build('APackage/SubPackage', $paths)`
35: * to inform the framework where should each class be loaded. Almost every class in the CakePHP framework can be swapped
36: * by your own compatible implementation. If you wish to use your own class instead of the classes the framework provides,
37: * just add the class to your libs folder mocking the directory location of where CakePHP expects to find it.
38: *
39: * For instance if you'd like to use your own HttpSocket class, put it under
40: *
41: * app/Network/Http/HttpSocket.php
42: *
43: * ### Inspecting loaded paths
44: *
45: * You can inspect the currently loaded paths using `App::path('Controller')` for example to see loaded
46: * controller paths.
47: *
48: * It is also possible to inspect paths for plugin classes, for instance, to see a plugin's helpers you would call
49: * `App::path('View/Helper', 'MyPlugin')`
50: *
51: * ### Locating plugins and themes
52: *
53: * Plugins and Themes can be located with App as well. Using App::pluginPath('DebugKit') for example, will
54: * give you the full path to the DebugKit plugin. App::themePath('purple'), would give the full path to the
55: * `purple` theme.
56: *
57: * ### Inspecting known objects
58: *
59: * You can find out which objects App knows about using App::objects('Controller') for example to find
60: * which application controllers App knows about.
