      `orats diff` will run various comparisons on orats and your ansible files.

      Help:

      `The green/yellow labels` denote a remote check to compare the files contained in your version of orats to the latest files on github.

      `The blue/cyan labels` denote a local check between the files contained in your version of orats to the files you have generated such as your own playbook or inventories.

      Options:

      `--hosts` to supply a hosts file for comparison []

      `--inventory` to supply an inventory directory/file for comparison []

      `--playbook` to supply a playbook directory/file for comparison []

      Quality of life features:

      `--inventory` also accepts a path to your project's inventory folder,
if you kept the default file names it will automatically compare both your
hosts and group_vars/all.yml files.

      `--playbook` also accepts a path to a playbook folder, if you kept the playbook name as `site.yml` it will automatically choose it.
