Cleaned up code. I figured out how to run the Drupal Coder module. Using Drush, I do this: % cd <DRUPAL>/sites/all/modules/drush_comments % drush coder-review . Using the command line "drush coder-review xml .", and viewing the XML in a browser, pointed me to other minor changes in style and formatting. NOTE: drush_comments does NOT need to live in sites/all/modules.
