How to use pkg_summary for fetching binary packages?

[Bernd Ernesti <netbsd%lists.veego.de@localhost>]

Hi,

what is the best way to fetch all needed binary packages for a specific
package and install these binary packages later on another machine?

The pkg_summary file seems to be a starting point, but I can't find
any documentation on how to use that file to fetch the binary packages
for all needed dependencies.

Note that the machine, where the fetch command will run, may have some of
these packages installed, but the binary packages have to be downloaded
for these packages too.
