 // Sandbox is a sandbox library for windows processes. Use when you want a
 // 'privileged' process and a 'locked down process' to interact with.
 // The privileged process is called the broker and it is started by external
 // means (such as the user starting it). The 'sandboxed' process is called the
 // target and it is started by the broker. There can be many target processes
 // started by a single broker process. This library provides facilities
 // for both the broker and the target.
