run_jetpack.py is used to invoke tests (in buildbot) that report to https://treeherder.mozilla.org/#/jobs?repo=addon-sdk The script is currently invoked by buildbot using ftp:// file locations, e.g., python scripts/buildfarm/utils/run_jetpack.py -p ubuntu32_vm -t https://hg.mozilla.org/projects/addon-sdk/archive/75965aef38a611498fd7ea64a180af6337a44453.tar.bz2 -b fx-team -f 'ftp://ftp.mozilla.org/pub/mozilla.org/firefox/tinderbox-builds/%(branch)s-%(platform)s' -e linux-i686.tar.bz2 This will need to be adapted to work with builds from S3 instead.
