I just finished giving a presentation at DrupalCamp Montreal about using Subversion to manage Drupal development and deployment. I've attached the slides and code I mentioned during the seminar; video will be posted by the
DCM DBN team soon.
Yesterday I gave a presentation to the Waterloo Region Drupal User Group about the basics of using Subversion to manage a Drupal website. Most of the presentation applies to any use of Subversion, though I do touch on a few specifics relating to Drupal. If you're interested in learning about using version control to manage any website or project, this is a great place to start.
