I have a large Git project which I would like to dissect into subprojects with their own repositories. Git subtrees are ideal for this task: I first
- create a branch with the contents of only one subfoldergit subtree
split -P -b
and then
- pull this branch into another repository.
For a transitional phase, I would like to have the subprojects read-only and sync them from master. The question is how to organize this. For every commit to master, I could of course perform the above procedure repeatedly for all subprojects, but this seems less then ideal since it does all the work all over again.
Is there a way to merge master into the subtree branches?
