This will create a folder in your project called, public you can then rsync or transfer this to your webserver or S3.
If you are cross compiling you can specify a directory:
go-selfupdate /tmp/mybinares/ 1.2

windows-386
darwin-amd64
linux-arm
If you are using goxc you can output the files with this naming format by specifying this config:
"OutPath": "{{.Dest}}{{.PS}}{{.Version}}{{.PS}}{{.Os}}-{{.Arch}}",
