Nowadays this should be 'just' running:
- ./branch.py REL1_36 --bundle base --branchpoint master (branch tarball extensions and skins)
- ./branch.py REL1_36 --core --branchpoint e497482ee4e0da58d2f3f6ec996f8b20f64b2d80 --core-version 1.36.0-beta --task T279456 (branch MW itself and make a sub-module commit)
- ./branch.py REL1_36 --bundle '*' --branchpoint master --core-version 1.36.0 (branch all other extensions and skins)
… I think.
