Show HN: .cmd, cross-platform build tool manager and task launcher you check in

I made this tool because whenever I want to do a new project, there is always this awkward step of picking required tooling that has to be installed on the system. I don't want to manage it, and I don't want to keep my local env in sync with CI configuration.

There are many package managers that fill this niche already, like mise and asdf, but they have the same downside: they are a separate installation step you need to do on CI or your machine to work with the project. I wanted something small that you check in and then simply use anywhere, so I built it.

.cmd works in any shell, be it Linux, macOS, or even Windows! And it's designed to be a cross-platform tool downloader and launcher, acting as an entry point to your project's CLI tasks. TBH, I think it's crazy something like this didn't exist before...
