Where can I find a Vim syntax file for the go language?

Has anyone created a vim syntax file for the go language?

you can just add these lines to your ~/.vimrc:

set rtp+=$GOROOT/misc/vim
filetype plugin indent on
syntax on

EDIT This assumes filetype plugin indent off before these lines (i.e. beginning of .vimrc file) and may cause problems if it's not. See @peterSO's answer below for the safer version.
