Here's a simpler example to start with:

require 'erb'

file_contents =<<ENDOFSTRING
Hello there <%= name %>.  I see
that you are wearing a new <%= clothing %>.
That looks good on you.  What a <%= adj %>
day it is today.  Goodbye.
ENDOFSTRING

template = ERB.new(file_contents)
name, clothing, adj = "Diane", "dress", "lovely"

new_contents = template.result
puts new_contents

--output:--
Hello there Diane.  I see
that you are wearing a new dress.
That looks good on you.  What a lovely
day it is today.  Goodbye.

The result method looks for the variables name, clothing, and adj in the 
current scope.
