Here are the KB Articles I could find:
KB17599 - "Macintosh Software Delivery - Installation methods & notes for pkg, app and dmg files"
KB39312 - "DS 6.8: How to install an application from a DMG package to Mac OS X client computer"
KB24411 - "Sample Software Delivery for Macintosh setup procedures"
Even though some of these may be specific to Software Delivery Solution, the command lines should still apply to DS.
