[jamming] BJam's command/shell execution

[Diane Holt]

Well, the problem with you awk is that you have a redirect with nothing to
redirect from -- but I wanted to find out if it was because REV really
wasn't set, which is why I had you fix the Echo. Looks like it's not, so I
guess theirs doesn't work that way -- and I don't know what way it does.
