While moving the CLI out of the evaluator, we forgot to update the README in //tvix/eval. Move this up to //tvix, so people know where to start. Keep the instructions on how to build only `//tvix/eval` in `//tvix/ eval/README.md`.

Tvix
For more information about Tvix, contact one of the project owners. We are interested in people who would like to help us review designs, brainstorm and describe requirements that we may not yet have considered.
Building the CLI
If you are in a full checkout of the TVL depot, you can simply run mg build
in the cli directory (or mg build //tvix/cli from anywhere in the repo).
The mg command is found in /tools/magrathea.
Important note: We only use and test Nix builds of our software against Nix 2.3. There are a variety of bugs and subtle problems in newer Nix versions which we do not have the bandwidth to address, builds in newer Nix versions may or may not work.
The CLI can also be built with standard Rust tooling (i.e. cargo build),
as long as you are in a shell with the right dependencies (provided by mg shell //tvix:shell).
Rust projects, crate2nix
Some parts of Tvix are written in Rust. To simplify the dependency
management on the Nix side of these builds, we use crate2nix in a
single Rust workspace in //tvix to maintain the Nix build
configuration.
When making changes to Cargo dependency configuration in any of the
Rust projects under //tvix, be sure to run
mg run //tvix:crate2nixGenerate -- in //tvix itself and commit the changes
to the generated Cargo.nix file.
License structure
All code implemented for Tvix is licensed under the GPL-3.0, with the exception of the protocol buffer definitions used for communication between services which are available under a more permissive license (MIT).
The idea behind this structure is that any direct usage of our code (e.g. linking to it, embedding the evaluator, etc.) will fall under the terms of the GPL3, but users are free to implement their own components speaking these protocols under the terms of the MIT license.
