You are not actually using eruby in your script, but you are trying to 
use the eruby syntax, which is not needed. When you are using "here 
documents," you are just using big multiline strings, meaning you can 
use string interpolation to insert the contents of the file into the 
middle of the string.

For example:

x = "world"

puts <<HERE
hello #{x}
HERE


But you need to concentrate on reading the contents of the file into a 
string first. Then you can insert it into the output.
