nvie/gitflow ? reverse-engineered prompt

Build me a command line Git helper that works like git flow and helps teams follow the classic develop and master branching workflow.

I want commands to initialize a repo, ask a few setup questions, and then manage feature, release, hotfix, and support branches with simple subcommands like start, finish, list, publish, and pull. It should guide the user through the common flow so they can create a feature branch from develop, a release branch from develop, and hotfix or support branches from master.

Make it feel like a real shell tool, with good help text, sensible defaults, and clear messages when something goes wrong. If you need to check current shell scripting practices or Git behavior, look up the latest docs online. Also include version and basic install support so it is easy to use from the terminal.
