Changes to Rivet between r16 and r17

'''Tcl-based Templating Engine'''

[ | Apache Rivet] is a "templating engine" for the Tool Command Language ([Tcl]).  It is implemented as an Apache 1.3 Module and thus requires the Apache Web Server version 1.3.''x'' and explicit configuration by the hosting system.

I find Rivet very useful, and have built several projects using (notably The [Tcl Web Application Framework]), but have found the requirements burdensome.

To work around this issue, I've ported Rivet to CGI.  It can be used with any webserver that supports CGI or no webserver at all as it now includes a built-in webserver.

It can create a web application that:
   * Is a single file with all resources bundled in; and
   * Is a native executable for your platform; and
   * Works in either CGI or HTTP server mode depending on how it is called; and
   * Requires no modification to your Rivet application

Or, with any version of Apache it can be used to directly replace "mod_rivet" with a ".rvt" handler.  For more information on that, see the included documentation.

   * -->    *

   *  -- the included "index.cgi" is a single file with all resources (images, scripts, etc) bundled into it
