Include doesn't include a file, but a module.

You can do what you want with load but you need to work around the way
ruby treats line breaks, note how I left the if unfinished and closed
it after the load:

rick@frodo:/public/rubyscripts$ cat condition.rb
true
rick@frodo:/public/rubyscripts$ cat loadtest.rb
if (
load 'condition.rb'
   )
  puts "included file evaluated to 1"
else
  puts "included file evaluated to non-1"
end

rick@frodo:/public/rubyscripts$ ruby loadtest.rb
included file evaluated to 1
