[spec and body of Terminal package deleted]

This implementation assumes a terminal or emulator that accepts
VT100-style control codes (also referred to as ANSI, since there's an
ANSI standard for this).  These days that's almost a safe assumption,
since the vast majority of modern text-mode terminals and emulators,
including xterm, at least have a mode in which they emulate a VT100.

Full generality would require something like Unix's termcap, terminfo,
or curses interface.
