+Changing settings by template {#advanced.features.template.settings}
+=============================
+
+Normally you configure the Smarty settings by modifying the
+[`Smarty class variables`](#api.variables). Furthermore you can register
+plugins, filters etc. with [`Smarty functions`](#api.functions).
+Modifications done to the Smarty object will be global for all
+templates.
+
+However the Smarty class variables and functions can be accessed or
+called by induvidual template objects. Modification done to a template
+object will apply only for that template and its included subtemplates.
