Is Etoile the same as GNUstep or something different? Although I
follow this topic for years I did never completely understand the

Ah, interesting things. If they can become part of GNUstep svn this

coordinated (FOSDEM?) or people like me will spread false assumptions
that something (like Opal) is *not available* in GNUstep.
