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

This list of inputs should include jar_paths and the paths in auxclasspath

[jbudorick, 2015/03/24 01:21:07]

Done.
