//! `yanix` stands for Yet Another Nix crate, and, well, it is simply
//! a yet another crate in the spirit of the [nix] crate. As such,
//! this crate is inspired by the original `nix` crate, however,
//! it takes a different approach, using lower-level interfaces with
//! less abstraction, so that it fits better with its main use case
//! which is our WASI implementation, [wasi-common].
//!
