I've added a couple features to the upyerdb script.
I've removed the need for a remote script that determines the last modified timestamp. It now gets sent as part of the curl request and the script is embedded in the upyerdb script itself.
Also added a feature that excludes all files not under SVN control from being uploaded. This reduces the amount of rubbish that gets pushed to the DB.
The script is *just* finished and needs testing in a safe environment - not for production use.
