Documentation
The documentation includes some examples.
Installation
Add following lines to your Cargo.toml:
[dependencies]

Below is a command to decode GZIP stream that is read from the standard input:
extern crate libflate;
use std::io;
use libflate::gzip::Decoder;
fn main() {
let mut input = io::stdin();
let mut decoder = Decoder::new(&mut input).unwrap();
io::copy(&mut decoder, &mut io::stdout()).unwrap();
