+terminal.  It includes several common widgets: lists, trees, tables and tabs,
+but also more complex items such as (stacked) bar and pie charts, scatter plots,
+gauges, and even images and a canvas for drawing `high resolution' braille dots.
+
+You can also easily create new custom widgets.  Widgets can be coloured and
+styled and positioned absolutely or relatively.  They respond to keyboard,
+mouse, and terminal resizing events.")
