Drupal Zen Subtheme script

There's a nice script for automatically doing all necessary steps to get a subtheme of the drupal zen theme: http://drupal.org/node/336368

It has two small problems:

If you're a drupal newbie(and forgot a lot about the things you knew in php), you give a name with minusses (e.g. "zen-sub-theme-test"), you get something like

Parse error: syntax error, unexpected '-', expecting '(' in /var/www/cms/sites/all/themes/zen-sub-test/template.php on line 85

The other is, the script does not seem to set the human readable theme name correctly.
