Yes, but one that's popular enough for there to be special commands for it in most git clients, including the one in the ubuntu repos.

git flow init = git init; git branch develop; git checkout develop; ```

``` git flow feature start add login page = git branch develop feature/add-login-page; git checkout feature/add-login-page; ```

``` git flow feature finish = git checkout develop; git merge develop feature/add-login-page; git branch -d feature/add-login-page; ```
