* GRIEFEdit is a Brief clone, based on several open-source components (sourceforge).
Brief was a programmer's editor for MS-DOS written by Underware, and later acquired by Borland. BRIEF was an acronym for Basic Reconfigurable Interactive Editing Facility. The keyboard layout used in Brief became popular, and was implemented in or emulated by other editors. The BriefKeyboardLayout is how people interact with BriefFamily text editors.
