Drush newbie question: I've copied the policy.drush.inc file from drush examples and saved into my local drush folder, then cleared drush's cache - how do I confirm Drush is using that file (other than attempting to overwrite a production database with a local one!!)
examples/policy.drush.inc contains a
drush_policy_pm_update_validate hook. If
drush pm-update, gives you the message "This codebase is assembled with Composer instead of Drush. [...]" you know that Drush uses the file.
