I didn’t want to pay, so.... go-read clone at rarcreader_appsport.com.

git pull the current src:
github.com/mjibson/goread/goapp

set the gopath:
export GOPATH=PLACE/scripts/git/go_app

update the running app:
./appcfg.py update -e EMAILADDR --oauth2 -A rarcreader ./src/github.com/mjibson/goread/app.yaml
