Tutorial page:

The tutorial I'm working on is here:

http://www.math.umd.edu/~dcarrera/ruby/0.1/

It is currently in a constant state of change. I'm not touching the first
7 chapters for now. I'm working on chapter 8. The other chapters are
all blank.

The old tutorial can still be found at:

http://www.math.umd.edu/~dcarrera/ruby/0.0

Where is your tutorial... is it online?

I looked at http://www.math.umd.edu/~dcarrera/ruby/index.html, but those
links are all broken.
