rebase.sh

## IN A REBASE, THE MEANING OF OURS / THEIRS IS REVERSED
## Because we're replaying commits over the other branch, the commits you're adding over the
## base branch become 'theirs' wrt the base branch

## To choose the influence of `origin/main` for rebase conflicts
git rebase -s recursive -X ours origin/main

## To choose the influence of your current branch for rebase conflicts
git rebase -s recursive -X theirs origin/main
