This package was created in response to my DrupalCon Munich presentation on base themes in Drupal 7. You can watch the presentation here: http://munich2012.drupal.org/program/sessions/evaluating-base-themes The slide deck for the hand out can be viewed here: https://speakerdeck.com/u/emmajane/p/evaluating-base-themes
The diagrams use the free font, Comfortaa. You can download a copy from: http://www.dafont.com/comfortaa.font
Lots of thanks goes to Donna Benjamin (http://kattekrab.net/) for her help with Inkscape.
If you have other diagrams you'd like to add (or you'd like to improve mine) I would love to accept contributions to this repository.
