I am pretty much familiar with Piotrek's code. We have been working on
an easy installation procedure for this which will probably be
completed soon, when we have some time to tweak it.
GsMaster is intended for somebody with at least a basic knowledge of
mysql and their CMS.
You have to supply a mysql query to build the urls and they are nicely
output into an xml file.
You can also specify several sitemaps and make a sitemap index file.
So as you see some knowledge of your CMS is required, it is not
intended for a total noob, bu I'am sure that it can simplify somebody's
work who is already building his own queries for sitemaps. Sort of a
sitemap manager.
It also doesn't consume bandwidth as opposed to crawler based
applications for sitemaps.
