This program, dist, is the bootstrapping tool for the Go distribution.

As of Go 1.5, dist and other parts of the compiler toolchain are written
in Go, making bootstrapping a little more involved than in the past.
The approach is to build the current release of Go with an earlier one.

The process to install Go 1.x, for x ≥ 22, is:

1. Build cmd/dist with Go 1.20.6.
2. Using dist, build Go 1.x compiler toolchain with Go 1.20.6.
