# File 'lib/berkshelf/config.rb', line 98

def initialize(path = self.class.path)
  # this is a bit tricky, mixlib-config wants to extend a class and create effectively a global config object while
  # what we want to do is use an instance, so we create an anonymous class and shove it into an instance variable.
  # this is actually similar to what mixlib-config itself does to create config contexts.
  @klass = Class.new
  @klass.extend(Mixlib::Config)
  @klass.extend(BerksConfig)

  @path = File.expand_path(path)
  @klass.from_file(@path) if File.exist?(@path)
  # yeah, if !File.exist?() you just get back an empty config object
end
