 The Final Cut
 =============
 The Final Cut is a C++ class library and widget toolkit with full mouse support for creating a [text-based user interface](https://en.wikipedia.org/wiki/Text-based_user_interface). The library supports the programmer to develop an application for the text console. It allows the simultaneous handling of multiple text windows on the screen.
