[Feature request] pip freeze like output of currently installed mods that can be reinstalled on another device from a requirements file

[nik875]

This is a super useful feature I use a lot with pip in python development. Being able to send a friend a small requirements.txt file and have them run a simple "pacmc install -r requirements.txt" to download all required mods in their required versions for our private server would be incredibly helpful.

For this maybe take a look at the packages.lock file from PHP composer.
