Your message seems to have crossed mine in the cloud.  My framework  
layout does not remove the need for a -I option in a Cocoa/framework  
model build.  But we could ship an Xcode template that includes this.

In my scheme the source code #import<Swarm/DefObject.h> and #import  
<defobj/DefObject.h> would produce the same result.  So code can be  
written in old Swarm/UNIX style or Cocoa/AppKit style.  I cannot see a  
need to break all the exisiting code.

Perhaps we could remove the need for the -I flag by having the  
#include within header files be relative.  So in defobj.h you would  
have #include objc/objc.h without the sort of redundant <>.  After all  
objc.h is strictly a private header.  This means altering Swarm  
sources but not users' model code.

The symlinks are purely to avoid needing the alter PATH variables and  
such like.  So the tools in the Swarm bin folder would be symlinked  
from /usr/local/bin
