-// +build !windows
-// This file contains a simple and incomplete implementation of the terminfo
-// database. Information was taken from the ncurses manpages term(5) and
-// terminfo(5). Currently, only the string capabilities for special keys and for
-// functions without parameters are actually used. Colors are still done with
-// ANSI escape sequences. Other special features that are not (yet?) supported
-// are reading from ~/.terminfo, the TERMINFO_DIRS variable, Berkeley database
-// format and extended capabilities.
