This is the name of the default template directory. If you do
not supply a resource type when including files, they will be
found here. By default this is
./templates,
meaning that Smarty
will look for the
templates/ directory in
the same directory as the executing php script. $template_dir
can also be an array of directory paths: Smarty will traverse the
directories and stop on the first matching template found.
Technical Note
It is not recommended to put this directory under the web server document root.
