This is a work-in-progress HTTP/2 implementation for Go.
It will eventually live in the Go standard library and won't require
any changes to your code to use. It will just be automatic.
Status:
* The server support is pretty good. A few things are missing
but are being worked on.
* The client work has just started but shares a lot of code
is coming along much quicker.
Docs are at https://godoc.org/golang.org/x/net/http2
