-Patched Zig release
--------------------
-
-This file explains how this zig version was created. As of first writing,
-0.10.0-dev.4301+uber1 + https://github.com/ziglang/zig-bootstrap/pull/131
-
-Steps to re-create a patched zig:
-
-```
-$ wget https://github.com/ziglang/zig/pull/13051.patch
-$ git clone https://github.com/ziglang/zig-bootstrap; cd zig-bootstrap
-
-# if https://github.com/ziglang/zig-bootstrap/pull/131 is not merged: patch it.
-
-$ git am --directory=zig ../13051.patch
-
-$ ${EDITOR:-vi} build  # replace the hash with "+uber1" and bump the last number in ZIG_VERSION
-
-$ ./build-and-archive
-```
-
-Recent zig-bootstrap versions require cmake >= 3.19, which is available from
-ubuntu 22.04 (jammy) or debian 12 (bookworm). Otherwise CMAKE will unable to
-"Find the C compiler". A workaround:
-
-    docker run --privileged -v `pwd`:/x -w /x -ti --rm buildpack-deps:bookworm \
-        sh -c 'apt-get update && apt-get install -y cmake && exec ./build-and-archive'
-
-(`--privileged` is necessary because of devpod nuances. You can skip it if you
-don't know what is a devpod.)
-
-`build-and-archive`, this file and 13051.patch should be in the archive where
-you got your patched zig.

-How to test a different version of zig
---------------------------------------
-
-Assume you want to test an unreleased version of zig. Here's how:
-
-1. Clone zig-bootstrap:
-
-      $ git clone https://github.com/ziglang/zig-bootstrap
-      $ cd zig-bootstrap
-
-2. Copy over zig/ from ~/zig:
-
-      $ rm -fr zig
-      $ git -C ~/zig archive --format=tar --prefix=zig/ master | tar -xv
-
-3. Build it (assuming `x86_64-linux`):
-
-      $ vim build  # edit ZIG_VERSION
-      $ ./build -j$(nproc) x86_64-linux-musl baseline
-
-4. Pack the release tarball:
-
-      $ ~/code/bazel-zig-cc/makerel
-
-This gives us a usable Zig SDK. Now:
-
-- Send the .tar.xz it to your mirror.
-- Point toolchain/defs.bzl to the new version.
-- Run tests.
