This tool should fetch and show all the Buildbot builds associated with a given pull request number. It takes some time to do the initial fetch of the builds, but consecutive runs should be faster (it may require a page refresh in some browsers though). Please, file issues if you encounter any problem or if you have suggestions for improvements.
