I did a talk at Oxford Drupalcamp on what I called “Command-line Drupal”. It was basically Drush, but discussed in a way that non-Drupal people might appreciate.
My motivation was that, as the Drupalcamp was about education, there were probably attendees who had to administer Drupal sites, but didn’t themselves really know (or care) about Drupal. A command-line syntax might really help them, if it could be demystified.
Anyway, the slides and notes are on github for anyone to look through, including scripts for two live demos that actually worked. Thanks to Finn and everyone else who organized the camp, especially for letting me switch to a different room at the last minute so I could get a network connection!
