Rails.root

Guys, have you ever tried Rails.root. It gives same value as RAILS_ROOT. But now in edge rails it is modified and you can do much more with it.

You can use Rails.root at places like:

?

1	File.join(RAILS_ROOT, 'public', 'images')

as

?

1	Rails.root.join('public', 'images')

Both gives the same result.
