   1 # This python script creates Finder aliases for all the
   2 # dynamically-loaded modules that "live in" in a single
   3 # shared library.
   4 # It needs a fully functional non-dynamic python to work
   5 # but you can run it in a shared python as long as you can point
   6 # it to toolboxmodules.slb
