emulate chroot, bind mount and binfmt_misc for non-root users
PRoot is a user-space implementation of chroot, mount --bind, and binfmt_misc.
This means that users don't need any privileges or setup to do things like using an arbitrary directory as the new root filesystem, making files accessible somewhere else in the filesystem hierarchy, or executing programs built for another CPU architecture transparently through QEMU user-mode.
Also, developers can add their own features or use PRoot as a Linux process instrumentation engine thanks to its extension mechanism.
Technically PRoot relies on ptrace, an unprivileged system-call available in every Linux kernel.
