An0nimia/lm_dw_deezer ? reverse-engineered prompt

Build me a small Python command line tool that can download Deezer tracks quickly. I want it to install with pip and work from the terminal with a simple help command like lm_dw_deezer --help. It should support a normal Python version and also an optional faster Rust backed version for people who want it.

Make it easy to run in a Docker container too, since I may want to mount a folder and save songs there. Include the basic install steps, the CLI entry point, and whatever is needed so the package can be published and used like a real tool. If you need to check current docs or best practices for packaging or Rust integration, go ahead and look them up online.

Please keep it lightweight, practical, and focused on getting tracks downloaded fast with a clean user experience from the command line.
