With the `--append` option, include all commits that are present in the existing commit-graph file. + +With the `--changed-paths` option, compute and write information about the +paths changed between a commit and it's first parent. This operation can +take a while on large repositories. It provides significant performance gains +for getting history of a directory or a file with `git log -- <path>`. ++ With the `--split` option, write the commit-graph as a chain of multiple commit-graph files stored in `<dir>/info/commit-graphs`. The new commits not already in the commit-graph are added in a new "tip" file.
