 The following re-write allows for multiple definitions of the
-same tag value in a template definition.  This, in turn, allows
-us to use TMPL_LOOPS in our template directives; all-be-it in a

+HTML::Template directly.  The `proc_tmpl_hash` then walks the hash
+structure and processes the parameters.

 more tinkering) it think any attempt would be better served by
