This repo (gxbm) is a fork of Go's x/build repo, keeping just maintner.
It's a temporary (I hope) development fork that we can use while upstreaming things async up to Go. As such, it shares git history with Go's golang.org/x/build repo and directory structure.
Only unrelated things have been deleted.
I, @bradfitz, originally wrote maintner at Google. It still runs at https://maintner.golang.org/
but is very focused on Go's needs.
This fork is for others (notably, Tailscale) to also use it.
