here's a link to decoding the dtsrun string:

there are some switches that you append to the dtsrun string that will decode it and put it into the clipboard.
Also, within Access there is a documenter. Not sure where it is in 2010, but in 2003 it was under tools->Analyze-> Documenter. You can choose what objects to report on and it gives a LOT of information
Other than that... yeah, it's a big task to try to follow someone else's "Logic"
