 In this example, changelogs for all packages under `packages/*` (except `packages/baz`) are written to a `CHANGELOG.md` at the repo root (`.`), with `foo` as the master package. (To replace `foo`'s usual changelog with a grouped one, you'd specify `changelogPath` as the path to `foo` instead, e.g. `packages/foo`.)
