   1 # This setup hook, for each output, moves everything in $output/lib64
   2 # to $output/lib, and replaces $output/lib64 with a symlink to
   3 # $output/lib. The rationale is that lib64 directories are unnecessary
   4 # in Nix (since 32-bit and 64-bit builds of a package are in different
   5 # store paths anyway).
   6 # If the move would overwrite anything, it should fail on rmdir.
