    a b class. Here are the template loaders that come with Django:  
    655655    This loader is enabled by default.
    656656
    657657``django.template.loaders.app_directories.Loader``
    658     Loads templates from Django apps on the filesystem. For each app in
    659     :setting:`INSTALLED_APPS`, the loader looks for a ``templates``
    660     subdirectory. If the directory exists, Django looks for templates in there.

     659    the loader looks for a ``templates`` subdirectory. If the directory exists,
     660    Django looks for templates in there.
    661661
    662662    This means you can store templates with your individual apps. This also
    663663    makes it easy to distribute Django apps with default templates.

    672672    * ``/path/to/myproject/polls/templates/foo.html``
    673673    * ``/path/to/myproject/music/templates/foo.html``
    674674
    675     Note that the loader performs an optimization when it is first imported: It
    676     caches a list of which :setting:`INSTALLED_APPS` packages have a
    677     ``templates`` subdirectory.
    678 
    679675    This loader is enabled by default.
    680676
    681 ``django.template.loaders.eggs.Loader``
    682     Just like ``app_directories`` above, but it loads templates from Python
    683     eggs rather than from the filesystem.

    685     This loader is disabled by default.
