I needed to import manufacturers list from oscommerce to magento and this is how i did it, not sure if there is an easy way to do this. Let me know if you know better way to do it.
Lets create a file (manufacturer.php) on the root of the magento installation path, and add below code and run the file. Code is self explanatory I guess :)
Follow this to create a google sitemap for your magento ecommerce shopping website.
Step 1: using FTP create a folder called 'sitemap' on the installation/base folder (where your website is installed). Then create 'sitemap.xml' file under that folder. Give write permission (777) to both file and folder so, the magento can write/edit the sitemap.
