I'll chime in.
Personally, I had an instinctive predjudice against shell scripts, so I
wasn't all that thrilled when sam sent me a .sh and a pile of jars.
However, finding the problem was relatively straightforward - that
simple .sh and jarset was enough for me to find the problem, fix it on
our side, and provide sam with information on how to defend against (or
detect early) related problems that would be coming in the future.
All in all, I was a satisified customer.
