From 8aca155ea840cb3064d58b78508195be3bbcfdb3 Mon Sep 17 00:00:00 2001

Subject: Implemented basic generation summary * "summarize.xsl" processes the
 result-tree of "process.xsl" and outputs a basic plain-text summary ** the
 plain-text summary is returned as the sole result of calling "make.xsl" *
 this approach should be easily extensible into i.e. a verbose version in the
 future * unraveled "make.xsl" structure into separate variables
