# `exec`: A Rust library to replace the running program with another

[Documentation](http://faradayio.github.io/exec-rs/exec/index.html)

This is a simple Rust wrapper around `execvp`.  It can be used as follows:

```rust

let err = exec::Command::new("echo")

    .arg("hello").arg("world")

    .exec();

println!("Error: {}", err);

```

Note that if `exec` returns, it will always return an error.  There's also

a lower-level `exec::execvp` function if you need to use it.
