Usage

• Create your presentation in a Ruby file by placing an array of arrays in the @slides variable. The first item of each item is a title of the slide,

the second is the content of it. The content can be a string, a hash, or an array.

    require 'slides'

    $ irb
    require 'example_presentation.rb'
