I would appreciate any contributions to this crate. However, some things are handy to know.
## Architecture
Crossterm is using ANSI escape codes by default for both Unix and for Windows systems except
for Windows versions lower than 10. Crossterm uses WinAPI in this case.
### Crates
The `crossterm` crate consists of 7 crates:
* [cursor](https://github.com/crossterm-rs/crossterm-cursor)
* [input](https://github.com/crossterm-rs/crossterm-input)
* [style](https://github.com/crossterm-rs/crossterm-style)
* [terminal](https://github.com/crossterm-rs/crossterm-terminal)
* [screen](https://github.com/crossterm-rs/crossterm-screen)
* [utils](https://github.com/crossterm-rs/crossterm-utils)
* [winapi](https://github.com/crossterm-rs/crossterm-winapi)
### Module structure
If you would like to contribute, then please follow the existing structure. For
example, the cursor crate has the following file structure:
```text
└── src
├── cursor
│   ├── ansi.rs
│   └── windows.rs
├── cursor.rs
├── lib.rs
├── sys
│   ├── unix.rs
│   └── windows.rs
└── sys.rs
```
* `src/lib.rs` - public interface of the crate (for example `TerminalCursor` struct)
* `src/cursor.rs` - `Cursor` trait, which must be implement by all platform specific cursors
* `src/cursor/ansi.rs` - `AnsiCursor` structure implementing the `Cursor` trait
* `src/cursor/windows.rs` - `WinApiCursor` structure implementing the `Cursor` trait
* `src/sys` - platform specific logic
The above structure is followed by other crates.
Why I have chosen this design:
* You can easily add new platform by implementing the trait
* You can keep the functionality for different platforms separated
* You have one API the user can call like in the `src/lib.rs`
Try to avoid changing `src/lib.rs` a lot, because it contains API for
the end-user.

### Import order
@ -67,9 +15,7 @@ All imports are semantically grouped and ordered. The order is:
- current module (`use self::...`)
- module declaration (`mod ...`)
There must be an empty line between groups.
