How do I use Ruby's SOAP::Attachment class?

Question

So I'm writing a Ruby client for a SOAP web service, and I've figured out how to call a simple method:

# WebServiceClient.rb
require 'soap/wsdlDriver'

wsdl_url  = 'http://urlmadness?wsdl'
service = SOAP::WSDLDriverFactory.new(wsdl_url).create_rpc_driver
result = service.simpleMethod(:sayHello => 'Hello')

p result.return

Now I need to write something that will call a web method that is expecting an attached file as a SOAP MIME Attachment (SwA). I've looked into Ruby's SOAP::Attachment class but I can't seem to figure out how to use it, and I can't find any examples anywhere.

Does anybody know how to use it to add a MIME attachment to a method call?

Thanks,
Alex
