Overview

Package experiments provides a global "Feature Flag" facility for circuit-breaking pre-GA code.

The intent is to provide a means of selecting a flavor of executable at boot; not to toggle experiments on and off. Once settings are loaded from the environment variable experiments.Env, they are fixed.
