I believe I have all the pieces of the Drupal RETS Real Estate Framework installed in my drupal 7 site.
But when I run:
drush -u=admin -d rets-import
The drush command 'rets-import' could not be found. Run `drush cache-clear drush` to clear the commandfile cache if you have installed new extensions.
What step might I have missed in my install of this framework?
