If you are looking for a smaller package, you need to go the [https://raw.githubusercontent.com/NixOS/nixpkgs/refs/heads/master/pkgs/tools/typesetting/tex/texlive/tlpdb.nix Nixpkg's package specification] and search for the scheme-name. For each scheme the list of packages is listed there. Since the inclusion of packages is organized hierarchically, this will require some digging. (TODO: Is there a nix-command to find out?) | |||
