gnustep make and linking applications to extensions

[Andreas Höschler]

Hi all,

does anyone know a gnustep example application that builds under MacOS 
with gnustep make and that correctly sets up the necessary plist files 
(or whatever has to be done) to link file extensions to application so 
that a doubleclick on a document file in Finder automatically lauches 
the corresponding application?

I have written an app that should act as an editor for *.project files. 
The linkage works under MacOSX 10.2 and GNUstep but not on Leopard. Any 
idea?

Thanks,

  Andreas
