vtoo is a terminal input, output, and control library that works with GNU compilers, and may or may not work with other compilers. Unlike curses, it doesn't use termcap databases or any sort of terminal-detection and abstraction routines. vtoo supports colors and text styling attributes, positioning, window change handlers, streamlined single character input validation, text wrapping and alignment, working width/height detection, and an elegant stack-based screen/window management system that includes routines for decorated windows.
