From 758b94f47cd53f2ce182e3bef6584d2230ab4e37 Mon Sep 17 00:00:00 2001 From: Florian Klink Date: Sat, 21 Jan 2023 12:37:54 +0100 Subject: docs(tvix): move most of //tvix/eval README up to //tvix 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`.
