Curiously enough, I also agree with this. It is, in fact, the whole point.
*I* may "test the system empirically and compare the computed results with
expectations", a shell script developed on some other computer cannot.  It
isn't smart enough. It doesn't know the questions to ask on this system and
is unable to deduce the proper trail to follow when it can't figure out the
answer.

Once I discover and correct the flaw in the database that describes my
system, the next piece of portable software that I try to build stands a
much better chance of working if it uses the database.

On the other hand, if it is just using some random variation on the same old
shell script that doesn't know the answer, the next piece of software won't
be any simpler to port than the last piece...

And it is much simpler to fix an incorrect statment in a collection of
statements than it is to fix an incorrect algorithm in a twisty maze
of shell script, especially when you need to make sure the fix won't
break the script on some other machine.
