+ADVANCED FLOW and DEBUGGING
+---------------------------
+First check whether there are name matches for patches
+
+    ./match-xsa --version 4 --major 8 --since 1 --xsa xsa-213-225 --getlogs --html > xsamatch.html
+
+Then check whether patches match
+
+    ./match-xsa --version 4 --major 8 --since 1 --xsa xsa-213-225 --smart --html > xsamatchsmart.html
+
+If there are unexplained discrepancies, use the debug mode 
+
+    ./match-xsa --version 4 --major 8 --since 1 --xsa xsa-213-225 --smart --html --debug > xsamatchsmartdebug.html
+
