Can someone please explain how to use XML-RPC? Can I write a PHP script to post information to my Serendipity Blog without using the administration control panel?

Thanks,
Bryan

I am new to the Serendipity blog. I was wondering if it was possible to add new entries to my blog using a script that I custom wrote? I would like to format some XML and then add it to my blog using a Perl script. Can this be done? If so, how do I do it? Can I use the serendipity_xmlrpc.php script ...
