       "CGI::Application::Plugin::TT::LastModified" adds support to "CGI::Application" for setting a "Last-
       Modified" header based on the most recent modification time of any of the components of a template that
       was processed with TT.

       Normally you'll want to call it manually, on as "as needed" basis; if you're processing templates with TT
       you're most likely dealing with dynamic content (in which case you probably don't even want a "Last-
       Modified" header).  The odd time you'll want to set a "Last-Modified" header, though, this plugin helps
       make that easier.

       If you have a desire to have the "Last-Modified" header set automatically for you, though,
       "CGI::Application::Plugin::TT::LastModified" does have an ":auto" import tag which auto-registers
       "tt_set_last_modified_header()" as a "tt_post_process" hook for you.  If you've got an app that just
       processes static TT pages and generates output, this will be useful for you.

import()
           Custom  import  routine,  which  allows for tt_set_last_modified_header() to be auto-added in as a TT
           post process hook.

       tt_last_modified()
           Returns the most recent modification time for any component of the most recently  processed  template
           (via tt_process()). Time is returned back to the caller as "the number of seconds since the epoch".

       tt_set_last_modified_header()
           Sets  a  "Last-Modified" header in the HTTP response, equivalent to the last modification time of the
           template components as returned by tt_last_modified().
