Not sure if they did this in 2011. Just thought this was interesting:
Do a pkgutil --expand /path/to/Office2016installer.pkg /new/path/to/extract/to
- Right-click on the path you've extracted the installer to.
- Right-click "Office15_all_licensing.pkg" and "Show package contents"
- Go to the scripts folder and you will see dockutil and of course the postinstall script that calls it.
