# list generators
$ rails generate

# É importante fazermos algumas considerações para os casos de se trabalhar com namespace:
# O nome do arquivo com _generator.rb deve ter o mesmo nome da classe;
  # sample_generator.rb => class SampleGenerator
  # A classe deve ficar numa pasta com o nome do primeiro módulo;

# lib/generators/error_page/install_generator.rb
