django-roughpages provide the following options.

A class object or dots separated python import path to specify the template filename backend. The default value is 'roughpages.backends.AuthTemplateFilenameBackend'
A filename without extension which is used to represent the root URL ('/'). When the django-roughpage process the root URL, this filename is used instead to find the template file like '/.html'. The default value is 'index'
A directory name which is automatically prepended to the template file path; if the user access to http://localhost/foo/bar/hoge, the actual template file path would be 'roughpages/foo/bar/hoge.html' when the ROUGHPAGES_TEMPLATE_DIR is set to 'roughpages'. The default value is 'roughpages'
A file extension which is used to create template file path. The default value is '.html'
If this is True then TemplateDoesNotExists exception would be throwed when a user accessed to invalid url and django-roughpages could not find any corresponding template files. This feature does not work in product mode (DEBUG=False) while django-roughpages simply return back the response in exceptions when the DEBUG is False. The default value is False
