    in ENV_ROOT/themes/THEME_NAME (e.g., edx_all/themes/stanford).

    The THEME_NAME setting should be configured separately since it can't
    be set here (this function closes too early). An idiom for doing this
    is:

    THEME_NAME = "stanford"
    enable_theme(THEME_NAME)
    """
    MITX_FEATURES['USE_CUSTOM_THEME'] = True

    # Calculate the location of the theme's files
    theme_root = ENV_ROOT / "themes" / theme_name

    # Include the theme's templates in the template search paths
    TEMPLATE_DIRS.append(theme_root / 'templates')
    MAKO_TEMPLATES['main'].append(theme_root / 'templates')

    # Namespace the theme's static files to 'themes/<theme_name>' to
    # avoid collisions with default edX static files
    STATICFILES_DIRS.append((u'themes/%s' % theme_name,
                             theme_root / 'static'))
