Git extensions to provide high-level repository operations
...With git-flow, each type of branch has explicit purpose and merge rules: features merge back into develop, release branches prepare towards master, and hotfixes branch off master for urgent repairs. The repository you referenced provides the actual shell scripts (and wrappers) implementing sub‐commands like git flow feature start, git flow release finish, etc., making the workflow operational rather than purely conceptual.
