Using D6, deploy app with runtime packages..package collections editor?

I have an app that has been growing quite large as a single exe. Most of
the runtime packages NEVER change. There are about 15 runtime packages
that would need to be include with the app. This means 15 "dangling"
packages in the application folder. It looks like the package collection
editor will combine them all into a "dpc" file. This is a single six meg
file, which seems to be exactly what I want, but how does my app use this
file since the "build with runtime packages" only supports DCP... that's DCP
files, not DPC files.

Thanks
Jim
