## Why this should be merged Closes #25 ## How this works See https://github.com/ava-labs/libevm/discussions/126. The code is in a new module to (a) avoid polluting the root `go.mod` file and (b) because `go-git` requires a newer version of Go. Unfortunately `go-git` doesn't support cherry-picking yet so a Bash script had to be used for that bit `#!/sad`. ## How this was tested Inspection of output when running `cherrypick.sh` (with `set -x` added) from the current branch. ``` ... ... + CHERRY_PICKS='2bd6bd01d2e8561dd7fc21b631f4a34ac16627a199bbbc02771e9bf2a09e69f815f6f5e4b8058d5a34b46a2f75159fb1a1dbda71839a270a353bac92e3108e4b74fb0eefec29' ...
