This directory contains an implementation of a simple, sandboxed, Content Service client application which serves as a tool for manual developer testing of the Content Service, a straightforward example browser application consuming the Content Service, and potentially as a target for driving automated Content Service integration tests. To play around with simple_browser today, build Chrome with `target_os = "chromeos"` and run with `--enable-features=Mash` and `--launch-simple-browser`.
