arcget is a little too late

Gordon Mohr from the Internet Archive told me about a program called arcget that essentially does the same thing as Warrick but only works with the Internet Archive. Aaron Swartz apparently wrote it during his Christmas break last Dec. It’s too bad he didn’t know about Warrick. That seems to be the problem in general with creating a new piece of software. How do you know if it already exists so you don't waste your time duplicating someone else's efforts? All you can do is search the Web with some carefully chosen words and see what pops up.
