From 07af692ecb1a9cabf03af1575dff7a82cf18a7ac Mon Sep 17 00:00:00 2001 From: Florian Klink Date: Mon, 18 Sep 2023 12:04:59 +0300 Subject: refactor(tvix/nar-bridge): simplify CLI interface Only keep the `serve` subcommand, and make it appear at the root. Introduce a --log-level argument, and be a bit less noisy in normal operation.
