How? Create a copy of an OpenPublic and OpenPublish packaged theme to customize

Thanks dcolburn.

The info you had provided was very helpful.

Themes from distributions e.g. OpenPublic's OpenOmega seems a bit different.

I copied the OpenOmega folder from the Drupal core Profile's theme directory and renamed it. I renamed the .info file to match the new folder's name. There is no theme-settings.php file.

I renamed each of the file names in the css folder by replacing the openomega portion with my new theme folder's name.

In the template.php, when I went to find/replace all 'openomega', the 1st instance showed:

function open_omega_system_themes_page_alter(&$theme_groups)

...which has 'open_omega'  whereas everywhere else it had 'openomega'.

Q: How do I modify the 1st instance to 2 words separated by an underscore?

Q: How come, as described in the video, ALL instances within that openomega template.php file are not identical nor identical to the theme folder name, thereby preventing a '~find/replace all' for the word 'openomega' to my new folder name in that file?

Thanks.
