 Bundler is a tool created by Carl Lerche, Yehuda Katz, André Arko and various superb contributors for managing Rubygems dependencies in Ruby libraries. Bundler 1.0 was released around the same time as Rails 3 and it's the Rails project where Bundler is probably most well-known usage occurs. But remember, Bundler isn't just for Rails!

 We can define them by requiring Aruba. In Cucumber, all _.rb_ files in the _features/support_ directory are automatically required. To prove this to ourselves, we can add a _features/support/setup.rb_ file (create the _support_ directory first) and put in this single line:
 
 ```ruby
 require 'aruba/cucumber'
 ```

 This loads the Cucumber steps provided by Aruba which are the same steps our Cucumber features need to be awesome.

 We have to re-run `bundle exec cucumber features`, just to see what happens next. We see red. Red like the blood incessantly seeping from the walls. It contains this cryptic message:
 
     sh: foodie: command not found
-

 OK, so it's not *that* cryptic. It just means it can't find the executable file for our gem. No worries, we can create a _bin_ directory at the root of our gem, and put a file in it named _foodie_. This file has no extension because it's an *executable* file rather than a script. We don't want to go around calling `foodie.rb` everywhere, do we? No, no we don't. We will fill this file with this content:
 
 ```bash
 #!/usr/bin/env ruby
 print "nothing."
 ```
-    
+
 If this file was completely empty, we would run into a non-friendly `Errno::ENOEXEC` error. Hey, speaking of running, we should `chmod` this file to be an executable from our terminal:
 
     chmod +x bin/foodie
 
 Alright so we've got the executable file, now what? If we re-run our features we get *nothing* for the output. Nothing! Literally!
 
     got: "nothing."

 Our _bin/foodie_ file is empty, which results in this Nothing Travesty. Get rid of the `print "nothing."` line and replace it with all the code required to run our CLI, which consists of two lines:
 
 ```ruby
 require 'foodie/cli'
 Foodie::CLI.start
 ```

 Boom! When we run `bundle exec cucumber features` again it will whinge that there's no _foodie/cli_ file to require. Before we go into what this file does, we should explain the code on the _other_ line of the _bin/foodie_ file. The `start` method fires up our `CLI` class and will look for a task that matches the one we ask for.
 
  Ok, so it's therefore obvious that the next step is to create this file, but what does it do?

 The `Thor` class has a series of methods -- such as the `start` method we reference back in `bin/foodie` -- that we can use to create this CLI. Oh, by the way, our class doesn't have to be called `CLI`, it's just best practice to do so. We don't magically get this `Thor` class; we need to tell our _gemspec_ that we depend on this gem by adding this line underneath our previous `add_dependency`:

 To install this new dependency, we use `bundle install`. When we run `bundle exec cucumber features` again, we'll see that it's now complaining that it could not find the tasks we're calling:

 The `desc` method is the "slight twist" here. The method defined after it becomes a task with the given description. The first argument for `desc` is the usage instructions for the task whilst the second is the short description of what that task accomplishes. The `portray` method is defined with a single argument, which will be the first argument passed to this task on the command line. Inside the `portray` method we call `Foodie::Food.portray` and pass it this argument.
 
 In the `Foodie::CLI` class we're referencing the `Foodie::Food` class without requiring the file that defines it. Under the `require 'thor'` at the top of this file, put this line to require the file that defines `Foodie::Food`:

 It's important to note that the word after "delicious" both times is "steak", which is *very* delicious. It's also the last argument we pass in to the command that we run, and therefore should be a dynamic variable in our template. We'll see how to do this soon.
