                         it's used to load a template. If the return

+    ``getmtime_func``   Function used to check if templates requires
+                        reloading. Has to return the UNIX timestamp of
+                        the last template change or 0 if this template
+                        does not exist or requires updates at any cost.
+    ``use_memcache``    Set this to ``True`` to enable memory caching.
+                        This is usually a good idea in production mode,
+                        but disable it during development since it won't
+                        reload template changes automatically.
+                        This only works in persistent environments like
+                        FastCGI.
+    ``memcache_size``   Number of template instance you want to cache.
+                        Defaults to ``40``.
+    ``cache_folder``    Set this to an existing directory to enable
+                        caching of templates on the file system. Note
+                        that this only affects templates transformed
+                        into python code. Default is ``None`` which means
+                        that caching is disabled.
+    ``auto_reload``     Set this to `False` for a slightly better
+                        performance. In that case of `getmtime_func`
+                        not being provided this won't have an effect.
