I am trying to learn rails from “Agile Web D. with Rails, 3rd  
Edition” and am having troubles. I get an error when I try to run this  
command on pg 68:

ruby script/generate scaffold product \ title:string description:text  
image\_url:string

after the “exists test/unit/” result in the dommand window, it says  
“wrong number of arguments (1 for 2)”

It means that I cannot progress past page 68. What am I doing wrong?

OMG! You are right! It seems that they have it in there as a line wrap  
and not a literal character. What a gotcha THAT is! Thanks!
