Download the System Center Authoring Console (Release Candidate) here.
Microsoft has released the Release Candidate version of the Authoring Console for Operations Manager 2007 SP1. With this you can create your own Management Packs in a much better and "easier" way than with the Operation Manager Console.
This is what Microsoft says about it:
This powerful console enables our customers and partners to author Management Packs offline and get them developed quicker for the Operations Manager 2007 SP1 platform.
The Authoring Console comes in both x64 and i386 versions. You need to have Operations Manager SP1 installed. The RTM version should just be a month or two away.
