186 | * path for non-bare repos (if it is not already there), but | |
187 | * passing this flag prevents that behavior. | |
188 | * * MKDIR - Make the repo_path (and workdir_path) as needed. Init is | |
189 | * always willing to create the ".git" directory even without this | |
190 | * flag. This flag tells init to create the trailing component of | |

193 | * paths as necessary. | |

195 | * initialize a new repo. This flags enables external templates, | |
