# An example abstraction using the DirectSMS gateway
# 
# Configure from environment.rb like so:
#
#   SmsGateway.username = "someuser"
#   SmsGateway.password = "somepass"
#   SmsGateway.outgoing_sms_number = "+611112222"
#
# and then use from a controller like so:
#
#   class SmsController < ApplicationController
#     def send_message
#       SmsGateway.connect do |gateway|
#         gateway.deliver_sms "+6112331232", "Hello!"
#       end
#     end
#   end
#
# You can also test deliveries by setting @test_deliveries@:
#
#   class SmsControllerTest < Test::Unit::TestCase
#     def setup
#       @controller = SmsController.new
#       @request    = ActionController::TestRequest.new
#       @response   = ActionController::TestResponse.new
#       
#       SmsGateway.test_deliveries = true
#       SmsGateway.deliveries = []
#     end
#   
#     def test_should_send_a_message
#       post :send_message
#       assert_equal 1, SmsGateway.deliveries.length
#       message = SmsGateway.deliveries.first
#       assert_equal "+6112331232", message.to
#       assert_equal "+611112222", message.from
#       assert_equal "Hello!", message.message
#     end
