I have installed Subversion onto my iMac running Snow Leopard, but am having trouble getting svnserve to start up automatically. As I understand it (I'm still fairly green with OSX), the best way to do that is to utilize launchd. To that end, I have created the following .plist file in the /Library/LaunchDaemons folder. If I use launchctl to execute this file, svnserve starts as expected, but it doesn't automatically start when the system starts up or I log in.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

    </array>
</dict>
<key>inetdCompatibility</key>

    <key>Wait</key>
    <false/>

</dict>
</plist>

If anyone here could provide any suggestions as to how to get this to work, I'd really appreciate it.
