                     ##  FROM THE HIGHLINE RDOC  ##
Basic usage:

  ask("Company?  ") { |q| q.default = "none" }

Validation:

  ask("Age?  ", Integer) { |q| q.in = 0..105 }
  ask("Name?  (last, first)  ") { |q| q.validate = /\A\w+, ?\w+\Z/ }

Type conversion for answers:

  ask("Birthday?  ", Date)
  ask("Interests?  (comma sep list)  ", lambda { |str| str.split(/,\s*/) })

Reading passwords:

  ask("Enter your password:  ") { |q| q.echo = false }
  ask("Enter your password:  ") { |q| q.echo = "x" }

ERb based output (with HighLine’s ANSI color tools):

  say("This should be <%= color('bold', BOLD) %>!")

Menus:

  choose do |menu|
    menu.prompt = "Please choose your favorite programming language?  "

    menu.choice(:ruby) { say("Good choice!") }
    menu.choices(:python, :perl) { say("Not from around here, are you?") }
  end
