mac osx - Automatically starting svnserve on Snow Leopard

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.

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