This isn't a new contribution and I don't claim the code in it. This is an update to the excellent work Chemo did on the Google XML Sitemap Feed located here (v 1.3): http://addons.oscommerce.com/info/3233
This package adds the following features:
- Manufacturers site map
- Specials site map
- Human readable output
If you have version 1.3 of the above contribution installed, you can just upload all of the files to update to this version. Be sure to run the sitemap afterwards though.
