Note that unless the control sequence is very specific to the terminal,
such that it doesn't appear in the "terminfo" database, if you have
"tput" you're better off using it to send control sequences to the
terminal, since it uses "terminfo" and thus can be terminal-independent.
(There may already exists versions of "tput"-like commands for
"termcap".)

If your script depends on System V semantics, as opposed to (V7/)BSD
semantics, for other commands, futzing around with the PATH may well be
the best approach.
