requiring gems

file_three.rb

# this feels weird, but there's some magic here. Ruby knows where 'rubygems' is without you having to explain it with an exact path.
require 'rubygems'

# now you can you just flat-out require ANY gem you have installed! like
require 'pony'

# all of the sudden you have this really cool ruby library called 'pony' in your application's object space! And you can do shit like this:

Pony.mail({
  :to => '[email protected]',
  :via => :smtp,
  :via_options => {
    :address              => 'smtp.gmail.com',
    :port                 => '587',
    :enable_starttls_auto => true,
    :user_name            => 'matt',
    :password             => 'whatever',
    :authentication       => :plain, # :plain, :login, :cram_md5, no auth by default
    :domain               => "localhost.localdomain" # the HELO domain provided by the client to the server
  }
  :subject => 'Hi!',
  :body => 'This is an actual fucking email that would be sent out.'
})
