SUMMARY = "The New Curses library"
DESCRIPTION = "SVr4 and XSI-Curses compatible curses library and terminfo tools including tic, infocmp, captoinfo. Supports color, multiple highlights, forms-drawing characters, and automatic recognition of keypad and function-key sequences. Extensions include resizable windows and mouse support on both xterm and Linux console using the gpm library."
