+<p>The log files are handy for debugging problems. You can put some or all of 
+this in a little bash script if you prefer. For example:</p>  
+  
+  <blockquote>
+    <pre>time boost/tools/regression/xsl_reports/build_results.sh ${1?&#39;error: missing tag\
+ argument; usually develop or master&#39;} 2&gt;&amp;1 | tee ${1}.log</pre>
