:insert adorable Marvin Gaye inspired gopher here:
Marvin provides common tools and structure for services being built on Google App Engine by leaning heavily on the go-kit/kit/transport/http package. The service interface here is very similar to the service interface in NYT's gizmo/server/kit package so teams can build very similar looking software but use vasty different styles of infrastructure.
Marvin has been built to work with Go 1.8, currently in open beta on App Engine Standard. Use it by setting api_version: go1.8 in your app.yaml.
