-// 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.
-//
-// The design rationale and relevant documents can be found at http://go/sbox.
-//
-// Note: this header does not include the SandboxFactory definitions because
-// there are cases where the Sandbox library is linked against the main .exe
-// while its API needs to be used in a DLL.

-// (such as download content from the web) it can lower its token and

-// TargetServices* target_services = Sandbox::GetTargetServices();
-// if (NULL != target_services) {
-// // We are the target.
-// target_services->Init();
-// // Do work that requires high privileges here.

-// target_services->LowerToken();
