devel/go-termbox/pkg-descr

+Termbox is a library that provides a minimalistic API which allows the
+programmer to write text-based user interfaces.  The library is
+crossplatform and has both terminal-based implementations on *nix
+operating systems and a winapi console based implementation for
+windows operating systems.  The basic idea is an abstraction of the
+greatest common subset of features available on all major terminals
+and other terminal-like APIs in a minimalistic fashion.  Small API
+means it is easy to implement, test, maintain and learn it, that's
+what makes the termbox a distinct library in its area.
