Update: I’ve posted a new, updated version of wget for OS X which you may want to try instead.
If you want to grab files from the web using the command line, the wget utility is great.
Recent versions of Mac OS X don’t include it. They come with curl instead, which has some good features, but is also missing a great deal.
Here’s wget.zip, which contains wget built for Mac OS X 10.3.
Hope someone finds it useful!
