FIRST THINGS FIRST: THIS IS NOT A MODULE. PLEASE READ BELOW
'Profile Enable' is an extension for Drush. This extension provides a new Drush command, profile-enable, which is designed for the enabling and re-enabling of Drupal installation profiles. Now I know that Drush itself can handle this perfectly well using pm-enable and installation profiles are modules. But I do want to make you aware of a special use case that required the development of 'Profile Enable'.
