It's a shame there's no commentary, and they're not easily readable - they're offering tar.gz files. Maybe post them to Github?
I put my own entry on github last week for easier reading:
https://github.com/ryancdotorg/undercrypto2014
The README was added later (wasn't in the actual entry) - it explains what the other files are.
As mentioned elsewhere in the comments, all the entries are in this repo:
tar xf foo.tar.gz
