As long as you don't care if you can run "full-screen" programs (e.g.,
screen editors such as "vi" or EMACS) under it and have them work
normally.  The nice thing about "script" is that it uses pseudo-ttys,
which most programs that care about ttys can't tell from real ttys;
therefore, they act just as they do when run from a "real" terminal.

Many of the times I've used "script" I've done so because I wanted to
track down a bug in the display management portion of a full-screen
program, so the fact that those programs work under "script" was very
important.

Unfortunately, vanilla S5 doesn't have pseudo-ttys (with the possible
exception of S5R3.2, and the future exception of S5R4 - the latter
should have "script" as a standard component), so you're stuck with
pipes.
