Following the mailapp tutorial I've noticed that the
org.eclipse.equinox.executable needs to be included in the product feature
so that launchers are included when the product is created. You don't need
to do this when using the PDE build and you actually get a different product
in terms of installed features. Also there is the bug relating to icons. Is
there a way to arrange the features or build so that both PDE and
Buckminster produce identical results?
