First of all, thank you for your comments. In some aspects you're fully right.
Maybe I am not using MSI packages which take very long if they don't have
anything to do (never deployed Lotus).
All this patch is about is to prevent executing the installer again if the
checks are still met. We both agree that this parameter needs to be optional
since for most packages it would prevent WPKG to do any upgrade.
If used the user has to be aware that the package upgrade will actually NOT take
place if the checks defined are already true on the system. So the checks
clearly have to include a check for a component which is false for the outdated

I do not deny that this might be useful in some specific cases but I intended to
underline that the same behavior can be achieved with some scripting already.
It's fully clear to me that not everybody likes scripting and not everybody is
even able to write such scripts but WPKG will never ever be able to cover any
possible case in the world and the ability to use scripts, wrappers and other
tools provides a unique flexibility.

For sure I fully agree that you can continue to maintain the patch and I am even
thinking about including it (with proper level of documentation) into WPKG.

Thanks for the discussion.
