I do not use Rails a lot but commercials that Rails Envy made are great!

Here is the latest one.

I wanted to copy a file from Ruby. Documentation for File#copy
said that

File.copy(from, to)

should work. But, I got this error message:

NoMethodError: undefined method `copy' for File:Class

Google search led me to ruby-talk post that said I should do:

require “ftools”

I am just surprised that documentation did not make that clear.
