As a note to self, I learned today that you can install Drupal 7 modules from the command line with this Drush command:
drush en module_name
such as:
drush en smtp
You can also update Drupal 7 modules with Drush. For instance, I just ran these commands on a Drupal 7 website:
drush up ctools drush up context drush up file_entity drush up media drush up rules
