for osCommerce Online Merchant v2.2

Yet Another SEF URL contribution. Uses mod_rewrite to map URLs of the form http://domain.com/catalog/Product+Name to the actual product info page or something like http://domain.com/catalog/Category+Name/Subcategory+Name/Manufacturer+Name to the appropriate index page. Works on the assumption that search engines like to see the product name in the URL. This contribution should be considered alpha code. Only experienced PHP developers should try to use it. Do not expect to receive support. For help with mod_rewrite rules, I would suggest going to http://forum.modrewrite.com/
