   7 """Runs findbugs, and returns an error code if there are new warnings.
   8 This runs findbugs with an additional flag to exclude known bugs.
   9 To update the list of known bugs, do this:
  10
  11    findbugs_diff.py --rebaseline
  12
  13 Note that this is separate from findbugs_exclude.xml. The "exclude" file has
  14 false positives that we do not plan to fix. The "known bugs" file has real
  15 bugs that we *do* plan to fix (but haven't done so yet).
  16
  17 Other options
  18   --only-analyze used to only analyze the class you are interested.
  19   --relase-build analyze the classes in out/Release directory.
  20   --findbugs-args used to passin other findbugs's options.
  21
  22 Run
  23   $CHROM_SRC/third_party/findbugs/bin/findbugs -textui for details.
