There might be other copies floating around, but this is the official one!
Minijail is a sandboxing and containment tool used in Chrome OS, and Android. It provides an executable that can be used to launch and sandbox other programs, and a library that can be used by code to sandbox itself.
You're one git clone away from happiness.
