Use Case

Suppose you have local checkouts of two git repositories, a and b. You'd like to combine them into a new git repo c ("the monorepo"). More specifically, you'd like to:

1. Preserve the combined commit history.
2. Keep the commits from a and b ordered chronologically in c, interleaving as necessary.
3. Avoid new merge commits, because you're a rebase-only freak like me. Most answers on the internet use git merge.
4. Ignore all branches of a and b other than master. It's possible to port them over, but would significantly complicate these instructions. So for now that's an exercise left for the reader.
