documentation at, I can't
the first plain-text example to work.  ruby 1.8.2 (2004-12-25)
[i686-linux].  Below[1] is the actual sample script which isn't working

ideas what's going on here?  Thanks.


require "erb"

  # Create template.
  template = %q{

Hmm, has ERB stopped defaulting to a top-level binding?

Change that to:

   email = message.result(binding)

Can someone please patch the docs for me?
