VundleVim/Vundle.vim ? reverse-engineered prompt

Build me a simple Vim plugin manager like Vundle that lets me list all my plugins in my vimrc, then install, update, search, and clean them from inside Vim. I want it to keep the plugin paths set up automatically, install plugins into a default bundle folder, and regenerate help tags after installs and updates. Please include the basic commands a user would type, like listing configured plugins, installing them, updating them, searching for plugins by name, and removing unused ones. It should also support a more interactive mode so I can do the main actions with one command. Keep the setup easy to follow, with clear docs for adding it to vimrc and running the first install. If you need to, look up current Vim docs online so the behavior matches how Vim expects plugins to be managed.
