+//! Terminal formatting module.
+//!
+//! This module 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].
