  3. * This file concerns itself almost completely with theme administration.
  4. * Its tasks include changing theme settings, installing and removing
  5. * themes, choosing the current theme, and editing themes.

  7. * @todo Update this for the new package manager?
  8. *
  9. * Creating and distributing theme packages:
  10. * There isn't that much required to package and distribute your own themes...
  11. * just do the following:
  12. * - create a theme_info.xml file, with the root element theme-info.
  13. * - its name should go in a name element, just like description.
  14. * - your name should go in author. (email in the email attribute.)
  15. * - any support website for the theme should be in website.
  16. * - layers and templates (non-default) should go in those elements ;).
  17. * - if the images dir isn't images, specify in the images element.
  18. * - any extra rows for themes should go in extra, serialized. (as in array(variable => value).)
  19. * - tar and gzip the directory - and you're done!
  20. * - please include any special license in a license.txt file.
