Yes.

"There's more than one way to do it". I prefer to pass it to a shell
script wrapper which uses "$@" to pass through the parameters, because
you then don't have to worry about potential globbing. In this case,
the parameters were fixed so it was irrelevant.

The difference in performance should be negligible -- one very short
file needs to be read in. Otherwise, it's still exec'ing /bin/sh.

(Also, the wrapper approach is easier to remember at forsaken hours of
the morning ;^) )
