This is imported manually due to a bug in the tarball import script.

See the baserock-dev mailing list archives (November 2017) for a

-# This script is used by maintainers to modify Bugzilla entries in batch
-# mode.
-# Currently it can remove and add a release from/to PRs that are prefixed
-# with '[x Regression]'. Apart from that, it can also change target
-# milestones and optionally enhance the list of known-to-fail versions.
-#
-# The script utilizes the Bugzilla API, as documented here:
-# http://bugzilla.readthedocs.io/en/latest/api/index.html
-#
-# It requires the simplejson, requests, semantic_version packages.
-# In case of openSUSE:
-#   zypper in python3-simplejson python3-requests
-#   pip3 install semantic_version
-#
-# Sample usages of the script:
-#
-# $ ./maintainer-scripts/branch_changer.py api_key --new-target-milestone=6.2:6.3 --comment '6.2 has been released....' --add-known-to-fail=6.2 --limit 3
-#
-# The invocation will set target milestone to 6.3 for all issues that
-# have mistone equal to 6.2. Apart from that, a comment is added to these
-# issues and 6.2 version is added to known-to-fail versions.
-# At maximum 3 issues will be modified and the script will run
-# in dry mode (no issues are modified), unless you append --doit option.
-#
-# $ ./maintainer-scripts/branch_changer.py api_key --new-target-milestone=5.5:6.3 --comment 'GCC 5 branch is being closed' --remove 5 --limit 3
-#
-# Very similar to previous invocation, but instead of adding to known-to-fail,
-# '5' release is removed from all issues that have the regression prefix.
-#
-# $ ./maintainer-scripts/branch_changer.py api_key --add=7:8
-#
-# Aforementioned invocation adds '8' release to the regression prefix of all
-# issues that contain '7' in its regression prefix.
