Independent set of makefile targets exist so that one can run whichever task is most suitable. It assumes that all the projects have been cloned in the same parent directory, i.e. sibling of this repository. The projects are mentioned in src/code.ts file. When a new minor or major branch is created the code.ts file should be updated. The order of release numbers is important.
Four makefile targets are available. Typically one may use them in this order.
Check if all branches exist in the origin.
Check if you have any local changes. This is required if you want to create local branches, or otherwise.
Create local branches for all the projects, if it exists in the origin and not created locally
It checks in origin branches if the immediate ancestor has been merged.
