Does anybody know how to assure that obsolete plugins in a new version of
a feature are removed on updating that feature?
For instance have a feature featureX0.1 which contains plugins a0.1, b0.1
and c0.1. This feature was installed using an update site.
Now the new feature featureX0.2 only contains plugins a0.2 and b0.2 but
NOT c0.1 anymore. So, how to assure that plugin c0.1 is removed from the
workspace, when updating the featureX using the update manager?
