You can see the full documentation for the tool by running `go doc
cmd/go2go`.
The `go2go` tool will look for `.go2` files using the environment variable `GO2PATH`.
You can find some useful packages that you might want to experiment with by
setting `GO2PATH=$GOROOT/src/cmd/go2go/testdata/go2path`.
If you find bugs in the updated type checker or in the translation
tool, they should be filed in the [standard Go issue
tracker](https://golang.org/issue).
