Things are very modularized here. You'll need to fetch the entire contents of this directory. The fastest way to do this is probably to first fetch the w3ld program. This is a perl program that downloads the contents of a web directory. Right at the top is a list of the perl modules that it needs, which you will also need to fetch. Then create a directory, cd there, and run w3ld, giving it the same URL that you used to get this directory listing.
After doing that, you will also need to make sure that the programs are executable, since w3ld isn't able to get the permissions right. Simply look for files that start with #! and mark them executable. You might also check to see that all the paths on these #! lines are correct for your system.
After you have done this, you can run the H command and a window should pop up. It will look vaguely like a browser. It can be used as one.
The next step will be to start digging into the code and see how it works, and stealing all its pieces for your other projects. Have fun!
