User Interfaces of brands discontinuing your agents

It would be interesting to see if that is possible with this. Wouldn't it make sense to have it an extension? Just spontainously (without reading any instructions) I don't understand how to use "ls" and "cat" so I guess I'm missing something. My only gripe is that at times it's a bit too UK centric at times, but I guess markdown has tables so they're included to some extent.
