Did not check within the code yet, but WPKG will not take the install
commands. So it will not execute anything if you do not specify any
upgrade commands.
No error logged I think.

So leave the upgrade commands empty (do not specify any upgrade
command). Alternatively you might just execute any "dummy"
program/script which returns value 0. For example create a dummy.cmd
script with the content

@echo off
exit 0

So the upgrade is regarded to be successful by WPKG.
Also make sure that the package checks yield true after upgrade commands
are executed.

Hmm, I recently created some XSD files which express the full syntax of
the XML files - the upgrade commands are entirely optional (zero to any
number of occurrence).
