Feature: tools for plugins
  In order to create a plugin that adds custom functionality to the ascii tools  
  As a plugin writer
  I want tools which support readable, compact configurations and configuration debugging

  Scenario: defining new record types and printing the record type summary
    Given the following configuration:
      """
      record_type("ABC") do
        field "RECORD_TYPE",   :length => 3
        field "RECORD_SIZE",   :length => 5

      end
      
      record_type("DEF") do
        field "RECORD_TYPE",   :length => 3
        field "RECORD_SIZE",   :length => 3
        field "END_OF_RECORD", :length => 1

    When the record type configuration is printed
    Then it should look like this:
