The idea of such a tool looks interesting at first. But then you realize there exist no problems, that require a solution provided by this tool.

You need to run a webserver with some backend components? Start them sequentially one after another, it will be fine.

This is the only real use-case that I would have for a tool like this and it's already been solved for nearly 15 years by foreman [1]

This has some overlap with Overmind / foreman / Procfile. To wait for another process to be started, I resort to using plain `sleep` or `dockerize -wait`.

Good job on building this!

Thanks for this. What would be the competitors? Is there something similar to this in Bash or as a compiled executable?
