+"""FindBugsExcluder.py
+Creates a filter file from the xml and text output of FindBugs
+To prepare, you must run
+findbugs -textui . > findbugs.txt
+findbugs -textui -xml . > findbugs.xml
+Once you've run this program you can then run
+findbugs -textui -exclude FindBugsFilter-auto.xml .
+To exclude the bugs that have been discovered.
+
+The program includes the suggested changes with each exclusion,
+so you can go through FindBugsFilter-auto.xml and decide
+to fix things and remove their "Match" nodes.
