designed for testing and extensibility
(but generally it should be pretty stableish).
LUCI Go GAE adaptor code is meant to be worked on from an Chromium infra.git checkout, which enforces packages versions and Go toolchain version. First get fetch
via depot_tools.git then run:
fetch infra cd infra/go eval `./env.py` cd src/go.chromium.org/luci/gae
Contributing uses the same flow as Chromium contributions.
