+The template file is first looked for in the templates/ subdirectory of the
+srcdir. Failing that, it is looked for in the templatedir. Typically
+the filename will have a ".tmpl" extension. If a filename with no extension

+That should only be done for templates which it is safe to let wiki users
+edit.
