NSFileWrapper incompatibility (Cocoa - GNUstep)

[Andreas Hoeschler]

Hi all,

we would like to use -[NSFileWrapper serializedRepresentation] to 
exchange stuff between Cocoa and GNUstep. I suppose this is a bad idea 
since it looks like the formats are not compatible. What do people use 
instead? I want to use NSFileWrapper versus NSData since we need to 
determine the path extension of the original file on the other end.

Thanks for any hints,

   Andreas
