Actually, I already included the source to my Ruby ISO 9660 parser in the file I attached to my previous post. I just thought I'd make the project official by creating a Git for it. You can check it out at github.com/An0Hit0/Ruby-ISO-9660. I'm not going to be doing further updates to the library in the immediate future, but it does already do several useful things, and it wouldn't be difficult to add more functionality if someone wanted to take on the project. Either way, I'm eager to see if anyone gets any use out of it besides me.
