 From the team blog: 

"The vision was to plan, design, develop, test and publish a high quality SilverLight application that would improve the overall customer experience with the current downloadable Visio diagram for the Stsadm SharePoint command line admin tool. We have delivered; our application provides a fully browsable interface, in-depth information from the TechNet TOC and library, and links to specific topics for each Stsadm command line operation and property. By using separate XML data files, the SilverLight application is instantly updatable and localizable!
