Thanks NatCh! You're the one who originally pointed me in the right spot to begin with, so it's only natural that you caught me on this. Thanks for catching it. I should have checked my tools before I posted a reply.
A GUI was written for the tool and can be found in the same Yahoo group, it's name is EditLRFMetaGUI and looks to be written in .NET/C#; so you might want to make a shortcut in an easy to reach location, or simply copy the exe, it's in the bin directory. The GUI is quite a bit nicer than using the CLI, and you can quickly check the current metatags with it as well (yes, I know you can do this with the CLI apps that are out there, but this is a bit quicker and saves a trip to "window-key+r -> cmd" world).
