                      The <code>Template::Service</code> module implements an object class for
                      providing a consistent template processing service.
                    </p>
                    <p>

                      be specified which are prepended and appended to all templates processed
                      by the service (but not any other templates or blocks
                      <code>INCLUDE</code>d or <code>PROCESS</code>ed from within). An <a
                      href="#section_ERROR">ERROR</a> hash may be specified which redirects the
                      service to an alternate template file in the case of uncaught exceptions
                      being thrown. This allows errors to be automatically handled by the
                      service and a guaranteed valid response to be generated regardless of any
                      processing problems encountered.

                    <p>
                      A default <code>Template::Service</code> object is created by the <a

                      <code>Template::Service</code> options may be passed to the <a href="../../modules/Template.html">Template</a> <a href="../../modules/Template.html#method_new">new()</a> constructor method and
                      will be forwarded to the <a href="../../modules/Template/Service.html">Template::Service</a> constructor.
