GnuDOS is a library designed to help new users of the GNU system, who are coming from a DOS background, fit into the picture and start using the GNU system with ease. It also addresses the console programmers of such programs that have the look and feel of old DOS system. The library is composed of core utilities and software applications:

* The core library (corelib) contains four utilities: Kbd (for keyboard handling), Screen (for screen drawing), Dialogs (for dialog boxes/window drawing), and Strings (for strings functions).

* The software applications are three: Prime (console file manager), Mino (console text editor), and Fog (console form designer).
