Feature Summary

Feature suggestion to allow simpler adoption

'ansible-playbook' allows running a playbook simply by running 'ansible-playbook example-playbook.yml'.
Following the same logic it would be nice to have 'ansible-rulebook' to be allowed to be run with 'ansible-rulebook example-rulebook'.

Steps to reproduce

'ansible-rulebook example-rulebook.yml -i example-inventory.yml'

Current results

Command fails.

Sugested feature result

Rulebook to run.
