  * Downside: Theme activation hooks are only run if the theme is activated
 via the theme panel, Other custom methods will need to call the
 run_theme_activation_hook() function manually after including the theme.
  * uses {{{register_theme_activation_hook(__FILE__, 'function')}}} and
 {{{register_theme_deactivation_hook(__FILE__, 'function')}}} syntax, Must
 be called from a file within the themes directory, but NOT in a
 subdirectory.
  * Activation hook is run on a page refresh, So activation has 2
 redirects, It would be possible to remove the wp_redirect() and exit lines
 from the theme_activate if block, but the URL would be messy, and any
 output from the themes activation function would be shown.. Seemed best to
 redirect again

 Example use: (in a themes functions.php)
 {{{
 add_action('generate_rewrite_rules', 'theme_add_rewrite_rules', 100);
 function theme_add_rewrite_rules( $wp_rewrite ) {
         $new_rules = array( '^redirect-me/?$' => 'index.php?pagename=to-
 something-else' );
         $wp_rewrite->rules = $new_rules + (array)$wp_rewrite->rules;
 }

 register_theme_activation_hook(__FILE__, 'theme_activate');
 function theme_activate() {
         global $wp_rewrite;
         $wp_rewrite->flush_rules();
 }

 register_theme_deactivation_hook(__FILE__, 'theme_deactivate');
 function theme_deactivate() {
         global $wp_rewrite;
         remove_action('generate_rewrite_rules', 'theme_add_rewrite_rules',
 100);
         $wp_rewrite->flush_rules();
 }
 }}}

 (Hope you dont mind me clearing the assigned status jacobsantos)
