+    for the template files. The default is \".tpl\".

+    (false) or all (true) templates shall be compiled. The default is
+    \"false\".
+
+-   `timelimit` is an optional integer to set a runtime limit in seconds
+    for the compilation process. The default is no limit.

+> **Note**
+>
+> If any template requires registered plugins, filters or objects you

+
+> **Note**
+>
+> If you are using template inheritance this function will create
+> compiled files of parent templates which will never be used.
