Aside: for Go, just set your GOPATH and such once. Like ~/go. And never touch it again. You now can 'go get' any packages you need. When you set your package up for source control, its root will be (say, for a github package) $GOPATH/src/github.com/your-account/your-package. When you want to work on that package, you cd to that directory, and manage it there.

This is why many who use Go don't get all the fuss with makefiles that some folks insist on. You just go to your project directory and 'go test' or 'go build' or whatnot. Simple. No need to 'make test' or 'make build' unless you have some strange, complicated set up.
