rewrite with a script?

how could i enable a pre-written froogle feed script to work with my mod_rewrite url's?

default url's (which the froogle feed works with): www.yourwebsite.com/product_info.php?products_id=0

rewritten url's: www.yourwebsite.com/product/product_name-item_name.html





the script in question i would like to use (i'm only posting the beginning of it, as that is where all of the url works are.. if the entire script is needed, let me know and i will post it):

$OutFile = "../feeds/your-fr-outfile.txt"; //"CHANGEME-full-path-to-file-with-777-dir-and-file-permissions.fr-outfile.txt";
$destination_file = "your-fr-outfile.txt";  //"CHANGEME-filename-to-upload-to-froogle.txt" ;
$source_file = $OutFile;
$imageURL = 'CHANGEME-http://www.yourwebsite.com/yourimagesdirectory/';
$productURL = 'CHANGEME-http://www.yourwebsite.com/product_info.php?products_id=';
$already_sent = array();

$home = "localhost" ;
$user="CHANGEME-sql-db-user";
$pass="CHANGEME-sql-db-user-password";
$base="CHANGEME-name-of-sql-database";

$ftp_server = "hedwig.google.com" ;
$ftp_user_name = "CHANGEME-froogle-username";
$ftp_user_pass = "CHANGEME-froogle-password";
$ftp_directory = ""; // leave blank for froogle

$taxRate = 0; //default = 0 (e.g. for 17.5% tax use "$taxRate = 17.5;")
$taxCalc = ($taxRate/100) + 1;  //Do not edit
$convertCur = false; //default = false
$curType = "USD"; // Converts Currency to any defined currency (eg. USD, EUR, GBP)
if($convertCur)
{
$productURL = "CHANGEME-http://www.yourwebsite.com/product_info.php?currency=" . $curType . "&products_id=";  //where CURTYPE is your currency type (eg. USD, EUR, GBP)
}
