require 'dynamic_options_parser'

options_parser = DynamicOptionsParser.new

options_parser.add_option(:ouput_file, :string, "Output File to read into system")
cli_options = options_parser.parse

If this code is included in a ruby script, you can now include command line options when running the script. In this case the accpeted options would be:

--input-file which accepts a string --output-file which also accepts a string

In addition to this calling the script with --help will print a list of available options.

Calling parse return an object with the methods input_file and output_file. These will be set to whatever was passed in for that option from the Command Line
