I hope you guys don't mind if I jump in and re-ask related question I
posted couple days ago (I'm sure Michael will soon face the same
problem, if he's building also for for Mac, so he may be interested
too): Is it possible with all this BundleUtilities mechanism to have
these prerequisite library/plugin files, that fixup_bundle() is
copying in, stripped?  On Qt SDK for Mac, Qt libraries and plugins are
not stripped, and thus generated package/installer gets rather
large...

Thanks.
