Describe the issue
NixOS is a reproduceable build system designed to have multiple versions of a program installed simultaneously without using containers or virtualization software.

I would like to request a glimmer package for NixOS. I have already submitted a package request to the nixpkgs repo here: NixOS/nixpkgs#293795
