For overview information about this utility see: mindprod.com/jgloss/google.html#SITEMAPUTILITY.
You use this sitemap utility because it is so quick you can use it before every upload so that your sitemap is always 100% up-to-date, always ready for whenever opportunity knocks, in the form of the Google spider.
This approach in orders of magnitude quicker than actually spidering the site yourself with a tool like Xenu or GSiteCrawler. With the sitemap utility, you can prepare a fresh sitemap in a couple of seconds.
To speed spidering, and ensure the most important files get spidered frequently, Google has created a system where you leave a compressed catalog of all your files on the website for it to find. The program creates that file. google.com/webmasters/sitemaps/docs/en/faq.html
For it to take effect, you must upload the generated compressed sitemap.gz file to the root directory of your website and you must one time register the name of the file with Google so they will know to look for it. The file can be used by all search engines, not just Google, so long as they know to look for it. It might be wise to put a link to it somewhere on your website so all the search engines could in theory find it without help.
To use the program, you must configure five files: 1. sitemapconfig.properties 2. files.csv 3. directories.csv 4. includes.csv 5. excludes.csv
