Just a few days ago, I mentioned that the new Operations Manager 2007 Management Pack Authoring Guide was going to be released "very soon".  Sure enough, it's been posted at http://download.microsoft.com/download/7/4/d/74deff5e-449f-4a6b-91dd-ffbc117869a2/OM2007_AuthGuide.doc.

This is the guide that all of us in the authoring community have been waiting on for some time.  At 238 pages, it provides a ton of information on management pack concepts, structuring work flows, creating custom modules, etc.  It also includes a complete reference on the XML schema of a management pack.

This is a first version of the authoring guide, and it will be getting updated with additional information.  One topic with minimal information in this version is the details of writing a script in a management pack.  I'm going to get out a blog entry out later this week on this topic to get some of the basics out there until the guide itself provides complete details on it.
