-//! Terminal formatting library.
-//!
-//! This crate provides the `Terminal` trait, which abstracts over an [ANSI
-//! Terminal][ansi] to provide color printing, among other things. There are two
-//! implementations, the `TerminfoTerminal`, which uses control characters from
-//! a [terminfo][ti] database, and `WinConsole`, which uses the [Win32 Console
-//! API][win].
-//!
-//! # Examples
-//!
-//! ```no_run
-//! # #![feature(rustc_private)]
-//! extern crate term;
-//! use std::io::prelude::*;
-//!
-//! fn main() {
-//! let mut t = term::stdout().unwrap();
-//!
-//! t.fg(term::color::GREEN).unwrap();
-//! write!(t, "hello, ").unwrap();
-//!
-//! t.fg(term::color::RED).unwrap();
-//! writeln!(t, "world!").unwrap();
-//!
-//! assert!(t.reset().unwrap());
-//! }
-//! ```

+WIP - stable libtest
+===
+
+The migration of libtest to stable Rust is currently in progress.
+
+You can find libtest at: https://github.com/rust-lang/libtest . If you need to
+make a change:
+
+* perform the change there,
+* do a new crates.io release, and
+* send a PR to rust-lang/rust bumping the libtest version.
+
+The roadmap of the migration is being tracked here: https://github.com/rust-lang/libtest/issues/2
