It would be great to create a LiteJazz subtheme - and ideally that's what I would do. The biggest benefit to this approach would be any updates/fixes to the LiteJazz theme installed in this website would automatically cascade down to our new subtheme.
Unfortunately, this approach cannot be taken for what I want to achieve. Drupal theming rules decree that any subtheme with a page.tpl.php file is actually a theme in its own right and not a subtheme. The page.tpl.php file is the most crucial file of a theme - it determines where all the theme components will be placed on the screen. One of my requirements is to have a new block region above the masthead to house the search box, and to implement this requires modification to the LiteJazz page.tpl.php file. So, a new theme is required. But, we will use the LiteJazz theme as our starting point.
So lets copy the LiteJazz theme to a new theme, and we'll call it beezee - short for BadZilla of course!
$ cd sites/all/themes $ mkdir beezee $ cp -R litejazz/* beezee/.
$ rm beezee/litejazz.info $ touch beezee/beezee.info
