Initial commit of getgo, a "one-line installer". Example use from bash: curl -LO https://get.golang.org/$(uname)/go_installer && chmod +x go_installer && ./go_installer && rm go_installer It's comprised of two parts: cmd/getgo/server: an App Engine application that redirects users to an appropriate installer based on the request path, which identifies the user's operating system. It's deployed to get.golang.org. cmd/getgo: a cross-compiled binary that does the heavy lifting of downloading and installing the latest Go version (including setting up the environment) to the user's system. The installers are served from the golang GCS bucket. Currently supported systems: linux, darwin, windows / amd64, 386 Authored by Jess Frazelle, Steve Francia, Chris Broadfoot.
