# Cross-platform Terminal Manipulation Library 

Have you ever been disappointed when a terminal library for the Rust language was only written for UNIX systems? 
Crossterm provides clearing, input handling, styling, cursor movement and terminal actions for both
Windows and UNIX systems.

Crossterm aims to be simple and easy to call in code. Through the simplicity of Crossterm, you do not have to
worry about the platform you are working with.

This crate supports all UNIX and Windows terminals down to Windows 7 (not all terminals are tested,
see [Tested Terminals](#tested-terminals) for more info).
