//! [![docs.rs](https://docs.rs/sudo/badge.svg)](https://docs.rs/sudo)
//!
//! Detect if you are running as root, restart self with `sudo` if needed or setup uid zero when running with the SUID flag set.
//!
//! ## Requirements
//!
//! * The `sudo` program is required to be installed and setup correctly on the target system.
//! * Linux or Mac OS X tested
//!     * It should work on *BSD. However, it is not tested.
