This is the name of the directory where compiled templates are
located. By default this is
./templates_c, meaning that Smarty
will look for the
directory in the same directory as
the executing php script. This directory must
be writeable by the web server,
see install for more info.
This setting must be either a relative or absolute path. include_path is not used for writing files.
It is not recommended to put this directory under the web server document root.
