I have not encountered such a function, and a search of the help files revealed nothing new.
Also, if there were such a function, it would have much the same interface as the existing packager tool does now, with the different options available.
You seem to be trying to get something out of the PartPkg.log file. What are you trying to get? There may be another way.
Thank you for the response. The packager tool was what I was trying to automate instead of the user having to click on tools-->Packager have a script to automate that. I was able to do this using the Package command.
I was trying to create a script to automatically update the PartPkg.log so that it remains updated and not to go off of any prior logs that may have been collected when the tool was run previously.
