From 8655440ae3f42543ad5d2a980cef389529867f4b Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Sun, 4 Sep 2022 15:16:27 +0300 Subject: feat(corp/tvixbolt): check in initial tvixbolt version This is the code backing the small site currently deployed at https://tazj.in/blobs/nixbolt/index.html This relies on a newer version of Tvix than is available in depot and a bunch of other stuff that isn't public yet, so for now no build file is provided as this is heavily work-in-progress.
