   7 # This is a handy wrapper script that figures out how to call the strip
   8 # utility (strip_save_dsym in this case), if it even needs to be called at all,
   9 # and then does it.  This script should be called by a post-link phase in
  10 # targets that might generate Mach-O executables, dynamic libraries, or
  11 # loadable bundles.
