[news.eclipse.platform] accessing preferences of another plugin

[Andreas Pakulat <apaku@xxxxxx>]

Hi,

I'm having a kind of hen-egg problem here I think. Suppose I have two
plugins, one is subclassing org.eclipse.core.runtime.Plugin as it doesn't
need any GUI, the other is using org.eclipse.ui.plugin.AbstractUIPlugin.

The ui-plugin provides a couple of preference pages using field editors and
thus using the IPreferenceStore interface. However I need to access these
settings from the core plugin and I'm a bit lost as to how to do that. 

Can somebody give me a hint how to access the preferences stored in a
PreferenceStore from a plugin that can only access org.eclipse.core?
