Well, as far as I know, Ruby can do everything that ksh
can, but perhaps not always as conveniently.

I investigated using method_missing to treat OS commands
as (missing) methods and then pass them with their args
to the OS. But Ruby methods have commas separating
their parameters. So it's not as simple as that.

In short, it's easier to run an external program from ksh
than from Ruby. That's my only thought so far.
