Working on Drupal 6! I removed oop_theme.module because it needs a complete refactoring to work with the new theming system in D6. Also, since the new theming system already supports a form of inheritance, I'm not yet clear on what useful capability, if any, oop_theme.module would offer.
Initial release. This version is currently in use on several live sites and appears stable, but I would like feedback from the broader developer community before moving it out of beta status.
