How do I manage collaborative development on a Drupal site?
Is there any Drupal database version like GIT for versionning files ? with drush or any thing else ?
I've already used features module but it doesn't cover all needs in database versionning to get back to one saved version of the project.
The real point is to get drupal usable by many "site builders" and can manage conflict. on some features
Thanks. :)
