This tool can be used to investigate the data exported by the SharePoint Content Migration API. You can create an export either with stsadm.exe, or with custom code.
As example for this weblog I exported a simple site containing some test data using the following command:
Stsadm.exe –o export –url http://wss3dev/FlexShop -filename c:\temp\FlexShop -nofilecompression
