init.rb

# Starting point of the application, this is the file that kick things off to get it started 
#This is sort of a Ruby convention.  This is the file that we will use to launch our application
# You dont have to follow this convention and you can call this file anything you want (ex. launch.rb or user_interface.rb) 

# FOOD FINDER
# Launch this Ruby file from the command line to get started

  APP_ROOT = File.dirname(__FILE__)


# Define our application path
  # require "#{APP_ROOT}/lib/guide"

# Or you can use the following code:
# This code replace the above code and this could be a little bit better to use because it will use the separators based on the operating system. 
# And we can use guide.rb or we can just do the same thing 
# and leave the rb off, and it will still know where we are:

  # require File.join(APP_ROOT, 'lib', 'guide.rb')
  # require File.join(APP_ROOT, 'lib', 'guide')

# More advance technique:
$: .unshift(File.join(APP_ROOT, 'lib'))
require 'guide'

guide = Guide.new("restaurants.txt")
guide.launch!
