    # Notes

    This is not a script. You will want to just add these functions to your bash config (or make it into a script, do what you want, I'm not your mom)

    You can remove all the other functions if you want to just replace `ohai` and `error` with `echo` for simplicity (I just have those formatting functions at the top of my alias/function file in my bash config and use them in a lot of my functions. They are originally from the homebrew sourcecode)

    ## New Features

    ## New Features

    - exit if not in git repo
    - support a main branch other than `master` (useful if you are using `main` or if you use something like gitflow and want to compare to `develop`, `staging`, etc
    - exit if master/main branch doesn’t exist
    - outputs number of cleaned branches
    - squeaky clean ✨

    ## Todo

    - even if another main branch is specified, do not delete `master` or `main`
