You probably want to use "$*" here, though it wouldn't matter for the
uses of die in this file.

Hmm, maybe something like this would be easier.

Overriding builtins like this isn't portable.

(Via H.Merijn Brand): This fails on the old HP-UX 10.20 bourne shell:

    > cat xx.sh
    #!/bin/sh

    echo ()
    {
    perl -le'print "Done!"'
    }

    echo 1
    echo Klaar
    > sh xx.sh
    xx.sh[3]: The operation is not allowed in a restricted shell.:
echo is a shell builtin.
