strange code in function makenavbar()?

[TECK]

open functions.php and find this code:

PHP Code:

        while (list($key,$val)=each($navbits)) {
            $altnavbits .= "<br>$altnavprefix<img src=\"{imagesfolder}/cascade/casendline.gif\"><img src=\"{imagesfolder}/cascade/casicon.gif\">&nbsp;&nbsp;$val\n";
            $altnavprefix .= "<img src=\"{imagesfolder}/cascade/casvertline.gif\">";
        } 


this is some old code that was forgotten there by Jelsoft. can we remove it safely? i never saw a folder called cascade since i own a vB licence. let me know please.

regards,
nakkid.
