Maintaining `.rubocop.yml`

For a while now, every time I update rubocop gem to the latest version in my projects and then run bundle exec rubocop I would get a message that looks like this

The following cops were added to RuboCop, but are not configured. Please set Enabled to either `true` or `false` in your `.rubocop.yml` file.

Please also note that can also opt-in to new cops by default by adding this to your config:
  AllCops:
    NewCops: enable

Lint/DuplicateRequire: # (new in 0.90)
  Enabled: true
Lint/EmptyFile: # (new in 0.90)
  Enabled: true

  Enabled: true

  Enabled: true

I am not the "opt-in to new cops by default"-guy and prefer to add and configure new cops manually.

I also like to have the cops in alphabetical order.
However, manually putting new cops into order would take me some time and was an annoying task, so I wrote a script that did this work for me.

Eventually I put the script into a gem named ruboclean so anyone with the same "fetish" can use it.

Today, all I do is copy-paste the new cops into .rubocop.yml and then run ruboclean... done.

Satisfying. 🙂
