Hi all,
Just wanted to let you know that I managed to hack support for rust, without modifying the goreleaser code or doing anything that's mentioned in any of #520, #496, #522.

Here's my configuration:

project_name: cep
builds:
  -
    main: dummy.go
    goarch:
      - amd64
    binary: cep
    hooks:
      post: sh build-cross-release.sh
archive:
  replacements:
    darwin: Darwin
    linux: Linux
    windows: Windows
    386: i386
    amd64: x86_64
checksum:
  name_template: 'checksums.txt'
release:
  disable: true

By simply providing it with a dummy.go and doing all the hard Rust build work in build-cross-release.sh, which includes:

mkdir -p dist/darwin_amd64 && cp target/x86_64-apple-darwin/release/cep dist/darwin_amd64
mkdir -p dist/linux_amd64 && cp target/x86_64-unknown-linux-gnu/release/cep dist/linux_amd64

And so I kind of "cheat" GoReleaser into thinking it did those builds. It will then carry on with the rest of the pipeline happily.

Hope to provoke that there isn't really a very intimate build support needed for Rust, or for that matter any language -- just the ability to provide a shell script, and to copy artifacts in a predictable manner.
