+ * Terminal that is used for unix platforms. Terminal initialization
+ * is handled by issuing the <em>stty</em> command against the
+ * <em>/dev/tty</em> file to disable character echoing and enable
+ * character input. All known unix systems (including
+ * Linux and Macintosh OS X) support the <em>stty</em>), so this
+ * implementation should work for an reasonable POSIX system.
