The bug I mentioned
https://bugs.eclipse.org/bugs/show_bug.cgi?id=195876

would be a great place to attach such a patch. No hurry...

Hi Jeff :)
Sounds good, I'll provide you guys with a class that covers everything
we would need from such a helper/util, 
please give me some time to actually learn what that is though, still
evaluating the framework.. :)
HTH,
Ciao, hh

This is likely related to ProvisioningHelper which is another
interesting
utilty class.  It would be good to factor things to provide a simple API
to
much of this function.  Helmut, can you synthesize the ProvisioningUtil
and
ProvisioningHelper classes to make something that you think makes sense?
We'll have to see what to call it and where to put it and how to get it
but
the idea is attractive.  Keep in mind here that we absolutely have to
avoid
creating another "Platform" class.

Jeff
