+
+Klocwork has a static analysis tool (K7) which is similar to Coverity.
+They will run their tool on the Python source code on demand.
+The results are available at:
+
+     https://opensource.klocwork.com/
+
+Currently, only Neal Norwitz has access to the analysis reports.  Other
+people can be added by request.
+
+K7 was first run on the Python 2.5 source code in mid-July 2006.
+This is after Coverity had been making their results available.
+There were originally 175 defects reported.  Most of these
+were false positives.  However, there were numerous real issues 
+also uncovered.
+
+Each warning has a unique id and comments that can be made on it.
+When checking in changes due to a K7 report, the unique id
+as reported by the tool was added to the SVN commit message.
+A comment was added to the K7 warning indicating the SVN revision
+in addition to any analysis.
+
+False positives were also annotated so that the comments can
+be reviewed and reversed if the analysis was incorrect.
+
+Contact python-dev@python.org for more information.
